The Impossible Bolt uses 2 Spitals, one large for the Bolt with large Spiral and one unvisual little one to the other direction wich can only geht taken by the Bolt with little Spiral

[@saipavangantla]

Ok.. I tried💪 1 it may grown like that or it may made carefully.🤔 2 Those two bolts has different. threads which makes them to move like that. 3 by slightly heating the jar we can also do that. 4 may be the bottle has a cut at other side or it may manifactured like that. 5 it's because of center of gravity. 6 it can be opened by taping hardly on the top and then moving the top part to one corner. 7 we can move them by rotating or spinning the toy on floor 8 the three may grown like that! 😂 9 there is answer it self in question it's all because of Jacob's ladder trick 10 hmm....I don't know.😉 11 by blowing air with straw!!!

Arrow and nut puzzle: insert the nut into the branch and wait for the plant to grow until the branch becomes thick enough to make the arrow.

[@yendavarunkumar6824]

Hai sir, I'm from India

[@bigredc222]

It says nothing was cut or glued. If the arrow put in a steamer for a while, it may be able to be squeezed enough to fit through. That's how they get the nail in the board, they put it in a steamer, and it will bend enough to get the nail in.

[@yencheonglee5940]

When the plant is still small we insert the nut into the branch and wait until it grows bigger then cut it out to make the arrow.

@Rab ton Daro It's stainless steel.

[@_.Infinity._]

7:19 it is because metals have faster rate of heat transfer than non metals. If you touch a metal and a piece of wood at room temperature, the metals feels cooler right? If you check it using an Infrared thermometer you'd find they're at the same temperature. What we humans feel is the rate of trnasfer if heat. When we touch the metal heat from our hand starts to flow towards the metal to achieve equilibrium and thus it feels cooler.

[@americansupervillain4595]

The impossible bolt is rather simple, two types of threads, fine and course. The fine threads are cut onto the surface of the course threads, just counter clockwise. One nut is threaded to use the fine threads and the other is threaded to use the course threads. I can program a CNC lathe to make these.

4:43 Spin it really fast at the centre

[@studyboy6335]

I have done it without seeing hind and ofcourse the comments. 1. The nail is carved from the wood....the nail was inside the wood ( maybe it kept with the seed) 2. Their are two bolt...one bolt is clockwise and the second bolt is fixed on 1st bolt ( maybe by glue or something else) which is counterclockwise 3. The golf ball was put on the top of the jar first, secondly it air was passed from the between of ball and the jar and it went inside 4. The deck of cards are placed on the bottle one by one by folding the cards...it is done very finishely...and then the padlock kept inside bottle tied with the cork Or The bottle was cut from bottom and the deck of cards were glued and the padlock were tied on the cork ( it was open when it went inside the bottle then locked and tied to cork very finishely) 5. It's an center of mass ( c.o.m) concept ...the net c.o.m were on the side of glass so it is balanced 6. The good thing about the object is that how the red thing were fixed inside the wood.

[@SoulEaterGT]

4:13 Impossible Dovetail solution is that the parts move diagonally to solve the puzzle. 4:35 solution is the centripetal force. To get the four balls on the corner, we need to spin it and the balls will go to the edges. 5:58 The ribbon changes its place whenever u change the sides.

[@AbhishekGaurVioletVenom]

Great answers. But the force is centrifugal not petal.

[@SoulEaterGT]

@@AbhishekGaurVioletVenom yeah, i thought i was writing it wrong. Btw thnx for correction

[@salokin1]

@@SoulEaterGT You weren't completely wrong ... a body requires a centripetal force, and therefore an acceleration towards the centre, to enable it to travel in a circle (i.e. stay in its original position when the block is spun). Because there is no such centripetal force it tries to move in a straight line but is constrained by the channel in which it sits, so moves to the outside. There is no actual "centrifugal force", just the absence of a centripetal force!

[@MrJdsenior]

@@salokin1 Thank you. Engineers/Physicists are FOREVER explaining this, "centrifugal force" is really a fictitious force, with the opposite sense to the REAL one...so why all those so called centrifugal pumps, etc.? WHO is the engineer/inventor/whatever that was asleep at the wheel, nomenclature wise? Or was it all in the translation? :-P Now what about the "force" of gravity. Obviously gravity can generate measured forces between masses, but is it ITSELF really a force, or just some space time gobbledygook, as that squirrelly haired fellow once posited? And, as they say, "What about Naomi?"

[@covfefewithdave2571]

1. wood was soaked, squeezed in a vise, then nail put in. Left to dry, the wood returns to its former size. 2. One nut has left, the other has right-hand threads. 3. Jar heated with hot water, then dumped out, golf ball placed on top sucked into it by steam cooling off. 4. Bottle built around the contents. 5. forks are balanced like tensegrity. 6. Dovetail joints really slide off. not how it looks. 7. spin it on the table. 8. same technique as #1 9. straps are folded under the bill when wallet is flipped. Straps NOT anchored in the center fold. 10. not enough detail is visible on my phone. Guessing, the strap is really an O-ring. 11. Wood is an insulator, aluminum is not.

[@TangoNevada]

4. Bottle built around the contents.? How does one do that without burning said contents?

[@im1who84u]

1. Already knew it. 2. Figured that one out. 3. Didn't know this one. 4. If that's how they did it. I call foul. 5. Knew this one already. 6.Figured this one out. 7. Knew it. 8. Knew it. 9. Have no idea what a "Mobius Strip" is. Never heard of it. 10. For this one I was thinking to poor water into the bottom part and then the wood cone topped cylinder will float up and you can just grab it and take it out.

[@Tsurnari]

The first one is made by placing one end of the wood in boiling water till it softens. Then you compress the wood so you can drive the nail in after which you place back in boiling water so the wood can reform. Let it dry, job done

[@bencrawshaw1227]

Yeah that's what I think

[@macieksoft]

3: Jar was heated and streched, they put the ball in, heated the jar again and shrunk it. Glass is elastic when heated and you can change the shape of it. You can do it multiple times, 4: They cut the bottle in half, put the stuff in, then they heated the glass to stick the 2 pieces back together. 5: Simple thing there. It is all about center of gravity. The place where toothpick touches glass is right at the center of mass of the whole fork contraption. 6: Turn the thing brown side down (to prevent bearing ball from locking it) and then slide it open. 7: Put the thing on the turntable and use centrifugal force. 11: Maybe hit the table with you'r fist hard enough for it to jump out? Use glue to remove it? Use vaccum?

[@themvids6087]

1st puzzle, the wood is soaked in hot water then both end pieces are squeezed with a vice allowing the nail to be hammered thru the centre lugs!

[@frankyw8803]

nope .

[@faradayfelix]

Only one end needs to be compressed, as you only drive the nail from one side. But, yes.....you hit the nail on the head 😅

[@chrisbresler5444]

I think one would have then been able to see at least some signs of that then, but the wood is totally smooth with no indication of any tampering. My take on this is that the nail just looks solid, but actually are in three pieces.

#1: Cut the wood, then soak it in water and clamp the end so the nail can be inserted. #2: The thread depth on the nuts is different so one travels clockwise and the other counter-clockwise. #3: Perhaps under high pressure the golf ball could be made small enough to go into the jar... #4: I'm not sure on this one... possibly the glass blown "around" the items? #5: Old trick... the balance is maintained because of the handle of the forks. #6: Cute.. nice use of dovetails. #7: Spin the cube. #8: Was the arrow put through the nut, or was the nut put on a branch and allowed to grow? #9: I want one. :D

HINT: When wood is wet, it can be compressed,. When dried it will come to its original shape! HINT: Ball into outer corners, just spin it!

[@mkllove]

@@BHAKTIBROPHY and CYCLOPS RESEARCH I had another solution, magnetism... if they are all staying in middle, just place a (circular if aval) magnet close, and just above them long enough to impart a polarity on them, then flip magnet from top to bottom, reversing magnet orientation to repel the balls away from magnetic field. A strong enough magnet would pin them away from center, perhaps using an electromagnet to be sure it worked ?

[@SupermarketSweep777]

The arrow and the bolt. The arrow was soaked in water for a while making the wood soft. It was then forced through the center of the bolt. Lastly the wood is allowed to dry back up.

It's done the same way you seal canning jars. Boil the glass, and the ball, leave the jar about half full of boiling water, quickly put the ball on top and push it in a little, when the water cools, it creates a vacuum, sucking the ball inside, then dump out the water and let it dry.

[@tom-kz9pb]

Pound a nail into a tree, wait a few years until the tree grows more and embeds the nail, then carve the whole thing out carefully, using something like a magnetic stud detector to see where the nail is. Or maybe melt the steel and pour it into a heat-resistant mold that is embedded in the wood, let it harden, and remove visible pieces of the mold (if you managed not to set the wood on fire).

[@NicholasMoore-hv6ho]

soak the wood, compress one end in a clamp, hammer the nail in and then re-soak and the wood expands back to its original state.

[@hainingshan2430]

no.8 This gadget uses a wood-enhanced hardness processing technology that is already energy-produced. It continues to press the wood with a mold in a dry environment of 100C. The limit is 24 hours to reduce the thickness of the wood to 1/5 of the original. Here, first make an I-shaped wooden stick with a thin middle and two thick ends, and use a mold to press the big end into the nut in a high temperature environment. Then put it in boiling water and cook it until it returns to its original size. After drying, carve the two ends into an arrow shape.

Its not enough for the threads on the nut to be different. There has to be two different threads on the bolt as well. They do this by making one much bigger than the other so you cant see the fine thread.

The coarse threads have fine threads cut into the peaks.

On the first one is the hole is drilled before the nail is inserted, if its hammered in, the wood might split. This makes it more mysterious since the nail can slide proving it is one piece.

[@doodle1726]

You're right aluminium is a good heat conductor while wood is not.

[@calvissuperman]

@@megangilbert9043 no, it's exactly what diane greene said. Metal always "feels" colder than wood, even though it's the same temperature. That's because the temperature is USUALLY lower than your own body, and thus heat transfer takes place. This is how you feel temperature, which this test shows you isn't the most accurate. The wood feels less cool than the metal because it transfers heat very slowly. This means it acts like an insulator and keeps the ice cold for longer, wheras the metal pushes all the heat it has into the ice very fast because it conducts heat very well.

4:32 !👍on rotating ,all 4 marbles will move to the end

[@miltonhalder2041]

Well I think there's an easier method. They mentioned that the centre is kept at slight lower level than the edges so that the marbles tend to approach the centre. So, if we flip the whole object upside down then the centre will be at higher level and the marbles will automatically go towards the corners which ar at lower level now. Well you can flip it by holding it above your head so that you can see the marbles moving to the corners....you know for self satisfaction😌

[@deepesh16b]

You are right 👏

[@knuckles1006]

The bolt and the fine thread nut are both left handed threaded. Also the thread pitch of the fine threaded nut looks to be 3 times that of the bolt. The inside diameter of the nut is only slightly smaller than the outside diameter of the bolt so that 3 threads of the nut sit perfectly inside each single thread of the bolt and goes on and off in the normal but left hand way. The coarsely threaded nut is threaded right handed. Its inside diameter is essentially the same as the bolts outside diameter so the nut goes on and off simply because of friction. For the golf ball in jar, just press the gulf ball into the jar.

1-??? 2- If my eyes are not wrong, the first nut had anti-clockwise fine threads, while the second one had much larger clockwise threads. 3- Hot water was kept inside and the bottle was shaken well. The water was taken out and the golf ball kept on the mouth of the bottle. The bottle was then kept in room temperature(or lower). The ball got sucked in. That, of course, is possible if the ball is not rigid. 5-The toothpick was kept on the rim of the glass in such a manner that the overall Centre of Gravity of the forks and the toothpick resided (theoretically ) inside the glass above it's base of support,provided there is enough friction between the toothpick and glass. 6-Push the upper block diagonally, after banging hard on top . 7-Spinning the box speedily over some point on it's bottom would employ centripetal force to do the rest. 8-The nut was passes through a young branch of a tree. When it grew up, carving was done to produce the puzzle herewith. I am a fan of Bobby Duke arts so this one was easiest for me. 9-I have built a Jacob's ladder. On opening the wallet from the other side, the ribbons exchange sides. So the cross comes to the left, holding the note, and the parallel ones on the right. 10-It would take my whole life to figure that one out. 11-Blow real hard on the box, towards the edge of the cone-tipped cylinder. This will cause the air to go inside and push the cylinder up. And if this is hard, Just tape an end of a thread to the cylinder, AND PULL IT!!!

The only way you could get the nail in the wood I can think of is steaming the wood to bend it.

[@arkansasmountainman]

You're close.. you place one end of the cut wood in boiling water for about 20-30 minutes, place that end in a vice and smash that end. Then you drill through the center pieces, insert the nail and return it to the boiling water for another 20-30 minutes. The wood becomes compressible when boiled and expands from being compressed when you return it to the boiling water. The same basic principle used to bend wood. Bending is done with steam but the thickness of this would take a very long time to steam it to be able to smash it enough to compress it enough. I didn't figure it out, I saw it on a KZbin channel. I know how some of the other ones work too. Just too long to explain in writing. The square with the X and you have to get the 4 balls out at the same time, simply spin it, centripetal force does the trick.. Good luck with the rest.

@@Zociety6477 take another look at the bolt. It has a left hand thread for its whole length. A right hand threaded nut wouldn't even fit on it. So why does one nut screw on toward the head while to other on screws away from the head when they're both turned the same direction? I know how it's done but it's not anything how you would guess.

In 3rd case The low air pressure inside the bottle pulls the golf inside to fill the empty space A vacuum can be created by removing the air from a space using a vacuum pump or by reducing the pressure using a fast flow of fluid, as in Bernoulli 's principle....

[@DUBSTEPPERRS]

The impossible nail is easy if you have the right tools. Like other tricks including wood, you just soak it till it’s pliable, use a vice to squeeze down one of the pegs on either edge (your choice) then hammer the nail through the two middle pegs. Allow the wood to dry and expand back to normal and voila!

[@nicbetgore3481]

I know the first one. You put the piece of wood in I think hot water and have pressure on the side pieces so it will shrink the sides and then you can put the nail in and let it dry and your done. Same kinda thing with number 8

3: heating the glass jar and opening it just enough for the ball to get in then form it back and cool it.

[@mkllove]

Glass doesn't expand or contract that much, the ball is compressible however, being hard plastic and a mostly rubber core.. so I believe you would place a glass jar with the ball sitting in mouth, perhaps supported by a tiny toothpick or item to keep pressure in bottle from differing from pressure around it.. then place in a pressuriz chamber to compress ball under hundreds of psi gas pressure so it falls into jar. Had thought maybe freezing ball and heating jar to achieve same effect but realized temp shock would break glass. This may also work under hydraulic pressure as well..

2. The "hint" is more of a complete reveal. 3. Heat creates a vacuum in a sealed chamber as it cools. Heat expands and heat softens. The ball is *only slightly* bigger than the mouth of the bottle. 4. That one is ... knot ... so difficult, especially for an experienced sailor. The deck of cards? Well that's just pure magic. 5. The actual "puzzle" is to hand someone two forks and a toothpick and challenge them to balance the forks on the glass and only the toothpick is allowed to touch the glass. You further confuse the issue by handing them the glass upside-down (although it still works that way) or on it's side (also works that way, too) and you stack the forks on top of the toothpick on the table. You swear it can be done and as long as they continue to try you will buy them their beer. BUT, if they fail they have to pay your bar tab (which you've been putting his beer on your tab the whole time). 6 . The "hint" is again more of a complete reveal. 7. Centrifugal force *does* exist! 1. & 8. How do you make a green bean go limp? Unfortunately for the sake of the challenge, the right hand side of the page is full of videos that show how it's done. 9.If a knot gets turned upside-down, it's still a knot, but what happens if you turn it inside out ... well it's still a knot but ... The *REAL* mystery is; who can get their hands on a U.S. two dollar bill these days? 10 A rubber "O" ring - a toroid, is not a Möbius strip, but with a really sharp hobby knife .... what happens if you cut a double möbius strip in half along it's length ... I'd bet Matt Parker, "Standup Maths" knows the answer. 11. One word; *buoyancy.* ?12?: Two words; *thermal conductivity* The counter intuitive part, if you could see the temperature indicators on the sides, is that the aluminum block gets colder than the wood block, yet it still melts the ice faster. Ask yourself, does a cold thing make something else cold, or does a warm thing make something else warm? There is only one correct answer and it's not "both". If you really want to scramble someone's brain, put the aluminum block in the refrigerator to bring it's temperature down first. It still works the same way as long as the room air is a comfortable temperature.

@@MrJdsenior It from the direction you cut the treads on the nut. Think of it as cross threading, best way I can explain it.

[@MrJdsenior]

@@ivangort5617 I think you might actually be onto something there. If the fine threads were multiple threads, like the one on some milk bottles, that engage and screw down in a fraction of a turn, and they were shallow enough, they might actually "ride" the top of the course thread, at almost no cutting depth, and those threads would be nearly invisible in the course bolt threads, especially on video. Which without reading it, I just copied the original commenter, with additions...because a single riding thread WON"T do what this nut is doing, ie. travel at that course thread pitch.

#1 put the woodpiece behind the nails head in boiling water. the wood gets soft. use a clamb to press the first edge behind the nails head, use a drill machine to drill a hole thru second and third edge. put the nail thru them. release the clamb. the wood gets dry and will take the origin position. that's all folks.
