Dead batteries bounce higher than full batteries... or do they? (2 Truths & Trash)

Thanks for watching!
Here’s a link to the Induction Heating video: • Building an Induction ...
I apologize for the worse quality, I was just starting out on KZbin when I made this lol.
Here's a list of questions answered in this video:
1. Do dead batteries bounce higher than full batteries?
2. Does a laser bend in a stream of water?
3. Does regular corn on the cob turn into popcorn if you place it in the microwave?
4. Do magnets fall slower through a copper tube?
5. Can a perpetual motion device that cycles a metal ball through a loop actually work without additional work input?
6. Can a small table made of string (Tensegrity Table) hold up somewhat heavy objects?
7. Can an induction heater actually make a fork red-hot in a short period of time?
8. Will a weight hit the floor when dropped with a counterweight that is approximately 13:1?
9. Can a green laser pointer charge a glow in the dark canvas?

man I love the 2 truths 1 trash series, keep it up! it really gets your brain thinking, and I'm glad to have a use for the wacky science facts I pick up here and there xD also, make sure to check that the ones selected as false are _actually_ false, and the ones selected as true are _objectively_ true, because I came across a few where I would know the physics of how it worked, but there was some unknown that I couldn't account for that skewed the answer. an example of one that I _got_ wrong, but I also _wasn't_ wrong about, was the episode with the hairdryer on a toy car. kzbin.info/www/bejne/bJy3k6ewa7qUd9E I actually tried it myself, and my hairdryer could easily do it, and nearly ripped itself out of the socket before I stopped it xD but don't worry, I know how to solve this issue, or at least I can help you predict when it might be a problem. you see, when the "trash/truth" is something that is not black and white, but is instead a gradient or spectrum, then it causes problems. like in my example, the hairdryer wasn't powerful _enough_ to move your toy car, but it _was_ enough to move my toy car. if the hairdryer is more powerful, then its no longer true. an example of a truth/trash you might make where you would encounter this problem, is: "you can throw a toothpick through paper." the problem with this is that there isn't a fixed speed for the toothpick or fixed thickness for the paper, so _you_ might have a setup that works, but ours doesn't, or vice versa. try to make sure we have enough information to get it right, and if there are any hidden variables, or any information we can't possibly know, then try to let us know as you explain what the truth or trash is. (it was kinda fun to make the hairdryer car tbh)

[@Lonrok]

I think the amount of fakes have to be completely random, that would make it much harder, but maybe even more fun

[@ellengrace4609]

But then there is no purpose in presenting three together. Each could be presented individually with the question real or fake. 🤷‍♀️

[@Lonrok]

@@ellengrace4609 That's true, so yeah, it could ruin it in some regards, but I would still like it

[@JaDroppingScience]

Yeah I think I'll probably experiment with occasionally making it random, but usually it's 2 true and 1 fake

[@TheSarge23]

Make the "random number of fakes" a sort of "bonus round".

[@matt92hun]

The physics stuff are easy tho, but I don't know what else would be this fun to watch.

[@DannyDaDino]

I watch these with my mom. It's really fun when we have different answers and I learn a lot from these videos. Excited for season 2!

I really love your ‘2 truths and trash’ videos, I really learn a lot in a non-boring way, I hope you will keep doing them. Love from Belgium

[@andreaskallstrom9031]

Love the videos! Personally, I am very happy always knowing that only one is fake. Often I’ll say things like “both 1 and 3 are fake” because I can’t wrap my head around either even though I know only one of them is fake. If both actually are fake, that will make the game almost impossible, and I guess I don’t want an impossible game, haha. But either way, love the videos and you make the call you think is best!

[@Spyd77]

I just want to say that I love those videos not just for their educational and entertainment value, but for a more important value nowadays: Lots of things you see in social media are fake and look credible if you don't do your due diligence of research, but most people don't even realize that, and take all they see in social media as fact. I hope everyone sends your channel to those kind of people that gobble fake news without even considering if there's any truth behind them.

[@justarandomdood]

Damn, I got the first 2 right because I knew how all 6 of the vids worked but I got stuck on the last one because I didn't realize that the color of the laser mattered, and I had seen all 3 of them "work" before Nice job, and congrats on finishing s1! Looking forward to sè soon :D

[@dudebladeX]

The copper one was legit? I did not know that. You learn so much from this channel…

[@TechyMage]

That's due to electromagnetic induction, u can say the coil acts at temporary magnet due to the induced current flowing through it

[@foogod4237]

Another cool detail: If you make a cut through one side of the copper pipe all the way down its length, but keep everything else the same, then the magnet won't actually be slowed down anymore and will fall at the normal rate. The break in the copper will prevent an electrical circuit from being formed in the copper surrounding the magnet, and without a circuit allowing the electrons to move freely around the magnet, the opposing magnetic field won't be generated.

[@61rampy65]

That magnet trick also works on an aluminum tube, but it will fall faster thru the aluminum tube. I used to teach that demonstration in my electrical classes. I used a plastic tube for baseline purposes, too.

[@sushantpvs5195]

@@foogod4237 Ah yes what you said was perfectly right!! Basically doing that would prevent the flow of current, as there is no short circuit right?

[@ediciusrift]

I like the ideas for the upcoming updates. Keep it up!

[@TheSarge23]

Got the first two right, but nr.3 threw me. Mostly because: How did you not burn your fingers off via heat-transfer in the first one? Also: We have a yearly "festival of lights" where I live, and one of the things on display is a "canvas" that can be charged up and make to glow just like your video with a normal smartphone light, so I never questioned lasers being able to do so. :)

[@GRBtutorials]

He didn’t burn his fingers because stainless steel has pretty low thermal conductivity (compared to other metals), so it’d take a lot of time for the heat to reach his fingers.

[@TheSarge23]

@@GRBtutorials Thank you! :)

[@foogod4237]

The handle of the fork is also long and thin, which further limits the heat transfer. It's basically like holding the metal handle of a pot that is sitting on the stove. I'm not sure that the laser-on-canvas thing is necessarily entirely false, actually. In that particular case it was not true, but I think it may depend a lot on what particular phosphorescent material is being used, and how receptive it is to various wavelengths, as there are a lot of possible options out there in that regard.

[@soundpreacher]

I thought the same thing. I didn’t realize the significance of the laser color before.

[@Stampyboyz]

Same for me but I didnt know it was a specific light color that charges up glow in the dark paint, so I guessed the second option

[@greatworldoftrains8147]

That’s a very interesting video. Great job. I really enjoyed watching it.

[@pixelpuppy]

creative content like this is why I subscribed! Can't wait for season 2!

[@Xanderviceory]

Please do season two with a mix of none are fake, all are fake and none are fake. But it changes up, basically "between 3 of the following videos it's up to you to spot if any are real or they're fake, let's begin"

[@joshcowley586]

This is the science show that we always wished far as a kid. Keep up the great work!

[@Hamster465]

The video ideas sound really good and you should definitely do them

[@rachelle10]

Good episode! I got the first and second correct, for the third I thought they all sounded plausible and I didn't pause in time to have time to think about it.

[@nutty8871]

Love these videos, managed to get the first 2 right :)

[@OWMANez]

Thank you for making our day ^^

[@thelongestrose]

The laser definitely threw me off. I'd seen all three things before, so I thought maybe the induction heater was messed with somehow to make it not real - turns out it was the laser all along!

[@TPKQ]

Thank you so much for your channel !!! Subscribed immediately. you are a hero! I always hated how harmful these fake science videos are to anyone that wants to learn and is not an expert. Especially to younger minds, these fake videos are abusive, accepting something as real when it is not, can cripple your entire thinking. Fake information is a growing reality and I suppose we have to learn. You are doing some real good work here for humanity !! Thank you !

Brilliant concept..

[@elemenewayfor796]

[@magnus0017]

I think none of the videos being fake would make the challenge interesting, but multiple fakes I don't think so. My favorite part is being sure something is fake, only to find out it's real. But will still watch whatever you do with these, looking forward to the new season.

[@SuperSilverSerpent]

I always feel like a huge nerd watching these and knowing which ones are real

[@AchillesPlus]

Heyyy just wanna share that we had this team of geeks in our company assembled during covid so for most of time we were working remotely. As a team building event we watched 2 Truth & Trash episodes together and we even got a score board to tally the correct guesses! It was really entertaining and we hope there will be more episode coming up!

[@vita7632]

The idea is great(at the end)

[@denisixi2762]

I would love to see season 2 :D

[@MagickKitsune]

Looking forward to Season 2! I got them all this time but you almost got me with the water laser, until it was up against corn which was so obviously fake. It could've been made more believable though: "If you dry corn in a dehydrator or leave it in the sun for a few days, it shrinks. You can put that in the microwave and get popcorn." It's obvious the drying step would require a jumpcut, so that's the perfect time to swap it with the popping cob. Then you wouldn't need to put it in the bag and we'd see it pop.

[@BariScienceLab]

Make one on April Fools where all 3 facts are true. Would be really funny!

[@dadmitri4259]

the perpetual ball, like most "infinite" kinetic desk toys, usually contain a magnet the magnet in this case puts some energy back into the ball as it runs down the track, so that it has enough to fly over the rim without the magnet, it would not make it back up due to the energy lost from friction

[@kevincronk7981]

0:49 I legit smelled the popcorn when I saw this

[@Nofxthepirate]

This was another case of me knowing for sure the first 2 were true, and thus the third one had to be false. You had me thinking there for a minute though!

[@srabb]

got all correct! nice video.

[@simonrespeto]

18 points from the entirety of Season 1 Cant wait for season 2

[@SmashPortal]

I've observed something similar to the induction heater in the form of a hair dryer. If you look down the mouth while it's running, you can see the coils getting red hot very quickly. What's weird to me is there's sometimes then a little jolt of electricity and they're suddenly not red hot anymore.

[@voideninfiknight]

About the two ideas you gave for season two, I would say do the sometimes multiple are fake, but to do none are fake woulf feel like a back hand to the face sence the point to point out which is fake.

[@declivity8151]

I would appreciate an occasional different format for a harder challenge. However, I think telling us how many are true/lies is better because it links them together rather than effectively just being 3 individual videos.

[@julianzacconievas]

I really like this series, feel free to add the no fake and multiple fake options, they'll make things harder. Maybe change the name though?

[@antoine5497]

That one with the nuts on a string made no sense to me, like, it just depends on the length of the rope and where you position your finger right?

[@seanewing204]

Please do both alternative types!

[@SkyfishArt]

I like the series but I feel some of these are a bit "gotcha", like not being able to pop regular corn, but you can if you buy special poppable corn. Then it comes down not to the trivia knowledge so much but that you have to have seen specifically what a poppable corn cob looks like. The green laser charging the glow paint also felt a bit on the gotcha side. I'd like to see more sort of common misconceptions being challenged more.

[@Sevicify]

The ball machine I feel was most egregious of this as it's a real machine that works as shown and technically fits the description that he stated of being cleverly designed so the ball has just enough energy to return to its original height to.

[@crazybird199]

very cool video!

[@norxcontacts]

I thought your channel was Jaw Dropping science.

[@sav4767]

The only one I missed was the green laser pointer. I guess watching a lot of Nile Red Action Lab TKOR and styropyro paid off xD

[@slyveonnumeros]

Nice, i got all right, and i didn't even knew it was a guessing what is real video, the last i were in doubt about the second or third, but i got all righ.

[@gideonteemsma1991]

I would love the multi fake or no fake things when ever I see one I love seeing these

[@nekaomi4251]

I got baited by the third part, instantly agreed that lasers could draw in a canvas painted with glow in the dark paint just cause I watched your first video. Turns out that you needed a blue laser, which I probably forgot.

[@nanunanu365]

3 for sure, popcorn is a different strain of corn altogether from normal "sweet corn". 2nd set number 2, there is some motor hidden remember seeing this particular "perpetual motion machine" somewhere else.

[@Morrigun-2001]

I personally do like the idea but maybe only for round 3. I really enjoy thinking about it for the rounds and I would love to see a switch up (maybe a witch video is True?) But I think if all of the rounds become more gimiky it might be a bit much.

[@riba2233]

Damn those batteries surprised me!

[@Cooljrcat]

good idea

[@9nikolai]

Having none to multiple fakes can make it much more difficult to guess, as we then can't prove that one is fake just by knowing that the other two are real, nor can we prove that the other two are true just because we know one is fake. Although if we can't know how many are fake and how many are real, you might as well just do one at a time, so you'd probably change it from "2 Truths & 1 Trash" to just "True or Trash?", which to be fair could make it easier to make them into multiple shorter videos if you wanted. Really like all of these so far though, so looking forward to more anyway!

[@G.O._MEDIA]

i love these

[@randomguyonline3340]

This one it really payed off watching channels like Vsauce and Backyard Scientist so I already knew certain ones were real

[@Joker22593]

Hint: the fake one is almost always the one where an object in concealed, which allows for cuts to edit any change imagineable.

[@ShamikShah]

Finally lost one - I had a 100% pass rate until the last question in this batch. I’m probably online way too much. 😂

[@LouieOnAGodDangShip]

Top 10 videos that will make you stay up all night

[@dandoriii2842]

I like the current format. Do what you want but my advice is to stick with what got you here.

[@OptimusPhillip]

Round 1) You can't just dry out sweet corn and turn it into popping corn. Popping corn is a completely different breed of corn from sweet corn. So #3 is trash. Round 2) This is a tough one. I know that magnets dropped through a copper tube do fall slower, because the moving magnet induces a current in the copper, and that current generates a magnetic field; I also know that ball and track toy does work the way it's shown, I've seen multiple independently made videos of it; and I know that that table works structurally, because the tensile forces in the strings all balance out. But considering that I do know the physical principles behind #1 and #3, I'm going to guess that #2 is trash because it doesn't work as described. (Well, I was kind of right. I figured there was some trickery involved in the way that toy worked, since if it were entirely physics-based it would violate thermo. But I didn't realize that there was actually a button involved, I figured that whatever trick it had was self-working.) Round 3) I know #1 and #3 work in principle, and I think I've seen #2 demonstrated in the past, so all of these have merit. I'm gonna have to go with #1, however, since I don't think induction heating is _that_ good. (Wow, I honestly did not see that one coming.)

[@hellohi2516]

I’m a bit confused on the second one of the last question, the one with the nuts on strings. What is it illustrating? Is the string wrapped multiple times around the finger? Why does it stop?

[@VasylOstapchuk]

Same question.

[@phoenixdowner]

I think you should turn this into a game show.

[@angusmctwangstick4079]

Does the laser beam actually curve or does it zigzag through international reflection?

[@ThopazProductions]

[@random_baffoon6114]

I only knew it was the corn one because you said it was Sweet Corn. The battery thing seemed logical and the light shining with water is a scientific fact. But only a specific type of corn can pop off the cob in a microwave

[@stevenjjohnson]

Tbh I don’t love the idea of having multiple or none be fake. Maybe it’s just that I don’t like change but I like the layout as you have it now. If you did add it, maybe add it to a few but keep most of them in this format. Either way, these are always super interesting! Thanks!

I got them all right (I ❤️ tensegrity tables, they're such a mind fuck to look at) but that last one was tricky and I got it right for the wrong reason, but I'll take it. I say leave it 2 right and 1 wrong. Makes you think more.

How can you touch a fork that‘s that hot as metals conducts heat well?

[@alikeseamen5859]

I think a cool idea would be a true or false round where there is only one video and the viewer would have to guess if it is true or false

[@toast_recon]

Oh, I got tripped up by the string thing in round 3. I didn't see the string got wrapped around your finger as the thing fell. Kinda feel cheated, i thought it was supposed to balance which is obviously wrong

[@SensibleDuck]

Yes good idea

[@karyoplasma]

Got the last one wrong. Thought the induction heater was fake because you held the fork by the handle and I thought it should burn your hand since metals do conduct heat quite well usually.
