Can a lemon charge a phone? (2 Truths & Trash)

Let me know in the comments how you did. Did you like the addition of non-experiment videos?
Here's a list of questions answered in today's video:
1. Does copper wire spin around a battery that is resting on a magnet?
2. Can you stack 3 dice on top of each other when the middle one is placed diagonally?
3. Can you create enough static charge with a pen can to attract the pen cap back onto the pen?
4. Can a paper clip float of the surface of a cup of water even though it is more dense that water?
5. Can you use a sharpie/pen to open a soda can by rubbing it back and forth on the lip?
6. What is the origin of the I/O switch on electronic devices?
7. Can you use a lemon to charge a phone?
8. Does the Eiffel Tower expand significantly based on the temperature?
9. Can copper wire with weights cut through an ice cube?

The fakt that ingenuo actually means gullible makes this funny in a way.

[@the_undead]

But also a little disrespectful

[@milesparris4045]

The pressure caused by the weight of the bananas didn't melt the ice. The copper wire did by absorbing the heat in the room and transferring the warmth through the wire.

[@sandstorm9991]

Right? When I saw the lemon one I knew it was fake but then when I saw the ice melting one I was really confused.

[@bradeggebraaten2141]

Absolutely true

[@57thorns]

This could be easily tested in a freezing environment. I believe the effect is there, but compared to transferring heat more effectively than the air, it is much weaker. And because the ice will refreeze, you will at one point have the wire going through the ice block.

[@eloizeaubin8724]

the paper clip trick was one of my favorite to do as a child. i was really good at it too! it's easier to get if you bend a second clip and use it to lower the first unto the water. also, it's a really neat way to show how dish soap destroys surface tension; a few drops in a bucket of water and all of the paper clips will sink in one go!

[@xilstus1776]

The phenomenon where ice melts under pressure is called regelation, but I don't think this is the primary reason why the ice was melting in that example. Copper is a great conductor of heat, and that wire is very thick. I believe that most of the melting action is due to the copper transferring heat from the room into the ice. Usually regelation is shown with a this thread or wire, so that less heat is transferred into the ice and the pressure the ice experiences is distributed through a smaller surface area, thus the ice experiences more pressure in the contact area.

[@ConstantChaos1]

Yeah also you need more weight for it than is given here, wirh that gage you'd be talking elephants of pressure is my guess it needs to be pretty heavy, this was just the conductor at work

[@Owen_loves_Butters]

Round 1: First one I knew was true, second one seemed plausible, third one seemed like too strong of an effect to be caused by static. Wasn't 100% sure though. Round 2: First one I've seen, second seemed plausible, third I knew was fake only because I already knew why the I/O were there. Round 3: You need dissimilar metals in the lemon to create power, so immediate dead giveaway and the other two made sense.

[@ConstantChaos1]

Well for round 3 he had 2 lies actually, c was also a lie, while it is true that pressure can melt ice you need a lot more than that to do melting, instead we saw the conductive nature of copper melt its way through ice, still cool and the video is legit but it's not from the pressure ( you need multiple elephants worth of weight to do that not bananas worth)

[@Owen_loves_Butters]

@@ConstantChaos1It actually can be done with a reasonable amount of weight, but a copper wire is too thick. An E string on a guitar actually works with a few pounds of weight attached.

[@ConstantChaos1]

@Owen_loves_Butters yeah but due to how weight distribution functions that weight requirement goes up quite quickly, in this case the thermal conductivity of the copper is a much more significant factor in any case.

[@DanielLCarrier]

You need upwards of a kilogram per square millimeter to have enough pressure to melt ice with that, and that's still just barely changing the melting temperature. I'd bet heat conduction played a bigger role there. Maybe when you first put it on there you could have that kind of pressure, but once the ice cube melts a little and matches the shape of that wire, that's a lot of square millimeters.

[@takagiichiro6430]

these videos are cool, i love science

[@Scapestoat]

The neat thing about these is that usually there's at least one that inquisitive kids will have figured out at some point. The BIC pen cap launching trick just sort of happened when idly absorbing information in class, and your hands need something to do. It holds charge? Sure, maybe, depending on the plastic, but not that much. XD

[@Mikeological]

cool thing about the ice cutting one is if you use a thin enough wire (and you might need a bigger ice cube), the ice refreezes together above the wire, so once it makes it through to the bottom and falls out, you're still left with one solid ice cube

[@ConstantChaos1]

Well that didn't happen for why he said it did so that's kinda a problem, it wad the conductive nature of the copper, pressure can melt ice but you are talking weights measured in elephants and not bananas, instead we saw the metal work as a conductor and dissipate heat into a concentrated area on the ice cube.

[@user-wo7rl4nm7w]

Some phone chargers have capacitors, you can fake it by pre plugging in the brick, and it will show its charging briefly when plugging in the phone

[@charginginprogresss]

2:00 as an italian, seeing "gullible" (ingenuo) written was a dead giveaway

[@JetJeb5648]

congrats on 1mil. subs

[@NuhDhulMitrain]

Lol the lemon was so ridiculous

[@insertnamehere4775]

Isn't the last one 3rd one not due to pressure but because the copper conducts the heat onto tbe ice making it melt faster?

[@JaDroppingScience]

Both, and having it be copper wire helps it melt faster than if I pushed down with some other line/wire.

[@TheDude50447]

The lemon juice thing had an oversight which made it way too easy. Samsung got 2 charging animations. The one you showed only shows when the phone gets fast charged. If youre using an older charger that cant supply as much wattage the animation is green not blueish.

[@bokkenka]

You can break open the charger, remove the guts, stick in a couple coin cells, connect them to the cable, and use the lemon to complete the circuit. That will actually charge your phone a little bit.

[@mickvaulsack]

AYYY MY SCIENCE TEACHER LESSS GOOOOO

[@bolo2393]

the I O thing is from electrical schematics and it really isnt letters, it is supposed to represent a circle and a line. It is used to show what state a binary switch is in on an electrical diagram, the line represents a connection and the circle represents a gap.

[@bobogus7559]

I think there are two main reasons why the lemon charging the phone didn’t work. First is that there were no electrodes - for a lemon battery to work, generally you need two different metals (like copper and zinc) to serve as electrodes to get current flowing. Second, the current generated is very low.

[@damiencouturee6240]

I just found your channel yesterday and I'm loving it lol. And I gotta say, the way you fake the false videos is almost more interesting than the facts themselves lol, you're one crafty dude

[@mcfixer9503]

1:42 I thought it was to indicate flowing circuit vs non-flowing circuit?

[@VeeOasis]

2:01 what launcher is that? or did you just make that pattern?

[@lextatertotsfromhell7673]

I’m pretty sure the I and O are to represent closed and open circuts

[@lllore9895]

I just want the lemon one to be real would be such a cool party trick lol

[@paulybeefs8588]

Until you stick your finger in a 120 volt alternating current lemon and get electrocuted because you forgot to hold a circuit breaker in your other hand.

[@goldberg91]

0:12 you can also do this with aluminum foil. just put a magnet to the bottom of the battery, and roll up aluminum foil

[@EdKolis]

I got them all right!

[@baalfgames5318]

Dang. The first one, I got all of them wrong, but this time I got all of them right. :)

[@PacificGrub]

Yes my lemon is now useful 🤣

[@Scapestoat]

Also; having a basic understanding of basic scientific principles / the laws of the universe seems to really help. As they apply universally, and the more of them you internalize, the more diverse things-you-never-encountered-before can be identified. But even then, sometimes there's a thing that feels right, and makes sense based on everything you know, but it ends up being clever trickery designed to exploit basic knowledge. The worst ones are combined with redirection! Oof!

[@hi-wf9ql]

round two, the one about I and O

[@magentamonster]

1:25 If I and O standing for "ingenuo" and "ozioso" was true, Wikipedia would not have put that information in an image caption of all places.

[@fauxnoob4157]

The battery one does work, but current flows from - to + not + to -. - has the electrons and + wants the electrons.

[@howdoipickaname9815]

1:10 i thought the sharpie/soda can one was fake, but when i learned it was real, i went to go test it and it worked! science is incredible :)

[@Sherkynerdo]

it's ironic that you said the blue ones are the worst, because every teacher in my middle school used jolly ranchers as rewards, and everyone was obsessed with the blue ones and everyone would try and trade for them.

[@karlfranz3819]

For the second one i admit i did not even qualify, as i am from Italy. If you wish to know, ingenuo means naive, and ozioso, while more probable as it could have been used in that context in the 800, means lazy

[@rausanrau9881]

You forgot to turn off super fast charging on the samsung which can only be achieved by using a brick with the super fast charging chipset. You could tell it's on due to the blue charging animation with the two lightnings.

The ice in the last one was cut by the copper melting the ice thermally not by the miniscule amount it is melted by pressure, to get that level of pressure you'd need multiple elephants worth of weight
