Here's a list of questions answered in this video:
- Can you light an LED with graphite lead and a battery?
- Can you light an LED with a large temperature difference between boiling hot water and dry ice?
- Can you use oranges to light an LED?
- Can you use glycerin's viscosity to prevent dye from mixing?
- Can a heat gun erase the ink of a thermochromic pen?
- Can burning two matches bond them together and cause one to lift?
- Can you bring back erased thermochromic pen ink using dry ice?
- Can you make slime with glycerin, baking soda, and contact solution?

[@samakshbharagav5012]

Love the "none are fake" and "multiple are fake" options. So Useful!!!!

[@LavaCreeperPeople]

Can Oranges power an LED?

[@pokedude720]

​@@LavaCreeperPeopleyep, since both it and lemons are Citrus fruit, they work the same as a lemon battery (the citric acid acts as a redox conductor)

[@karimek10]

Well

[@TaxeAndStuff]

neat episode! i do like the "none are fake" option as it's always been there and adds some variety

[@9nikolai]

The simple addition of the possibility that none might be fake removes the usability of the elimination method to determine which one is fake, so we do actually have to consider each clip individually.

[@Art.and.Hamsters]

@@9nikolai Yes!

[@aterxter3437]

Funny fact about erasable ink being returned with cold. In 2017 there had been a trend about erasable pens, and the thing was that this year, there was a heatwave following the written exams of the Baccalauréat (French equivalent of the High School Diploma). The examiners had to put the answer sheets in the freezer in order to be able to read anything

[@wincentywilk7511]

They allow using erasable pens on exams? In Poland you can only use black non-erasable ones.

[@russianyoutube]

​@@wincentywilk7511 same in germany, but we use blue ones

[@shracc]

that seems like bullshit, unless they stored the tests in a black truck in the sun it wouldn't erase, and those pens wouldn't be allowed in most countries.

[@vukkulvar9769]

@@wincentywilk7511 I assume not, but there is always people forgetting their pens, or pen having a malfunction. I could see malicious people lending an invisible ink pen or defaulting to it when the other pen do not work.

[@ssgoko88]

​@@vukkulvar9769that's not what invisible ink is dude.

[@MotoDash1100]

The 2nd round was def giving me a hard time, if one had to be fake I was thinking the heatgun, but also remembered heat being used in some CSI like way with pens. Completely forgot about the none being fake option, and for Round 3, up until you said the syrup would make the ball bounce I thought you'd do a All Were Fake as well.

[@CeruleanTrafficlight]

I do really like the none/multiple are fake options, the possibility (however small) they bring makes me try and justify why I think the options are fake/not rather than metagaming knowing it's certain to be 2T/1L. Plus, that dry ice tip might just salvage some of my old notebooks, so thank you for that!

[@The_Forge_Master]

It doesn't have to be dry ice. You can just put them in the freezer and have the ink reappear.

[@KlaireLarnia]

Liked "none are fake" as I was convinced you would not use it. Great set of things, so yeah please do more!!!

[@NukeBrazil]

Same

[@emilyleppik2787]

It actually IS possible to generate electricity directly from a temperature gradient like 1B, you just need a special device for it. My grandparents have one!

[@polarknight5376]

kzbin.info/www/bejne/Zqm8YWmGiZp9eqc Mehdi did a pretty cool video on it.

[@rorydakin8048]

yes that threw me for a loop, then I remembered my material sciences classes I took ages ago stating that thermocouples (devices that produce a voltage in response to a temperature differential, the sensor component of digital thermometers and thermostats) need to be made of two different metals and the metals need to be directly in contact. Once I realized the metals were not in contact I understood that the effect shown was false

[@dotcomgamingd5564]

I really liked the none were fake option. it really stumped me.

[@guyblack9729]

i love the none/multiple fake options! They keep me from feeling too confident about process of elimination answers haha

[@Ninja20704]

The first one i was tempted to say none because i remember that a temperature difference can actually create an electric potential difference which is how thermocouple thermometers work.

[@crazycoolbanana1631]

That was so fun! That was a big plot twist too!

[@jffrysith4365]

I'm glad you used the none were fake. like most of the comments I was originally stuck because you never used it before, but I got it in the end!. Also, glad to see you still rarely use it. It'd be much less interesting if almost every video had no fakes.

[@Kirmo13]

1/3 you got me with the second one and I thought you were going to pull a "non of them are correct" on the third

[@ichbrauchmehrkaffee5785]

1:35 ohoh.. I can allready hear Destin: "DID SOMEBODY SAY LAMINAR FLOW?"

[@reikiboi5514]

That "none were fake" caught me off guard, not bad

[@ekamarie6632]

I was right! I was like I know for a fact the the last 2 are real, bc I lost a whole semesters worth of notes bc I left my back pack in my car on a hot day and we had a test so when I went to grab my notes we were allowed to use I didn’t have any. And the match trick I’ve done before. And the first one just felt real, I use food coloring a lot not in glycerin specifically but it makes sense. And yep they were all real.

[@AltName7]

Dang, the sun ate your notes.

[@Bryce_the_Woomy_Boi]

Imagine if there's a video where its all A's or something except the last one. It'll be like a school's multiple choice quiz

[@Mmouse_]

Fun fact: hot and cold can be turned into electricity (dry ice would be used for one side), it's called a peltier device. Kinda weird, because they work both ways... Give it power and one side gets cold the other hot, but if you make one side cold and the other hot it gives off power... Kinda like a motor/generator scenario.

[@barttemolder3405]

I think the viscous solution would force the pingpong ball up when dropped, only to slow it down again because it clings to the ball. I bet that if you had separated the ball and the syrup with a layer of cling film (assuming that does not stick to the ball) it would shoot up out of the beaker.

[@habby4377]

Aahah I lost this one completely, great video. Btw, is this the end of the season?

[@JaDroppingScience]

No, I did 8 episodes in Season 1, so I'm thinking I'll do 8 again this season.

[@ThemightyTho]

I got all three right this time!

[@serraramayfield9230]

i got 6/9

[@tosendeelemente8948]

Nice got all of them Btw first video of your channel nice one

[@davidpawson9047]

The question is, "Which of these claims is/are fake?" This allows all or none to be so.

[@SimonaDaRat]

I finally got all of these correctly . Feels good

[@ralphmueller3725]

yea, the hot to cold would only work if a proper thermocouple is made. requiring iron and copper wires to be linked.

[@fishinggang9299]

Awesome video! 👍

[@pof8913]

On the 3rd round I'd remembered seeing your video on the subject, and I thought that it wouldn't work because the syrup was sticky. Also, you can't see the reflection of the color of the syrup in the bowl.

[@vukkulvar9769]

My thought process was "viscous syrup would act like glue, and cleaning syrup from the flooring would be a pain in the ass, so it's the fake one"

[@Alternate-H123_22]

3:04 LOL WHAT?

[@kakyoin5862]

i was so torn between the none were fake one, I didn’t even consider none as an option! Lol

[@Art.and.Hamsters]

Yessir, I got em’ all right!

[@nehakarnikraut8305]

And if you lied, that oranges can power an LED, and actually, oranges can't power an LED, you will get a visit from huggy, wuggy

[@Scapestoat]

"None of them are fake" makes me feel bad for mindlessly discarding the least likely one. So I guess they're educational, and keep users on their toes?

[@renegadethesandwing02050]

1:37 ive seen smarter every day's vid on this and the science behind it is extremely fascinating

[@ichbrauchmehrkaffee5785]

Seen Round one in a short, but the DEAD giveaway is, how bright the LED is and how fast it turns on

[@SomethingCheese]

Somehow I almost always get these right and at this point its getting creepy

[@noxious_2.06]

Waaaait so you can make erasable pen appear again if heat made it disapear ?!? I may be able to retrieve some old drawing then :D

[@ThatGirlMisty]

I was almost perfect! Rounds 1 and 3 I got correct, and round 2 I knew the erasable ink trick was real and the matches trick was real but I guessed that the vegetable glycerin was fake.

[@user-ci5vn9uu6y]

the friction pen with dry ice got me I thought it was fake

[@SniffyTugBoat]

I thoroughly enjoyed "none of them were fake"

[@cameronbruce412]

I have those pens number three is a type of welding so I though it was either a or none

[@bykurt_is]

Ahh damn you got me lol this would totally be a fun mobile game to play

[@samakshbharagav5012]

knew nothing about them ..... Same as always

[@hadensnodgrass3472]

I got all but the last one, right. What would happen with oobleck?

[@timturner7609]

Does the water increase the bounce? Itd just bounce anyways when it hit the floor

[@andrewprahst2529]

Man that clear glue got me thirsty

[@neo1754]

i feel so betrayed ☠️☠️ I thought there HAD to be 2 truths and one trash, since it’s the name 😭😭

[@wansichen3743]

the water and dry ice one isnt that how thermocouple works?

[@ranvircheema7564]

I make the slime the same way it showed in the video so I knew the slime one wasn't fake

[@Iron_Soil]

Got 1 and 3 right but i thought that all where fake in 2 💀

[@Dragonbl8zer]

i have an idea for a two truths, one trash episode: 1: if you put a string of metal beads in a measuring cup or beaker, and drop the bead sting out of the cup, the beads will levitate off of the beaker. 2: if you put powdered mercury phisionate in an aquarium tank and apply heat, long tendrils will begin growing out of thin air, this does generate toxic fumes, so use cation while preforming the experiment (it could be something like this, I found it on Outrageous Acts of Science, and I feel like it should be here). 3: if you heat up a pipe, the pipe will sing, you can pour the sound into a cup and back into the pipe as shown here. Answer: #3 and #2 are false, there is a metal mesh that is heated up creating the sound tipping the pipe just stops the noise, you cannot pour sound. for #2 there would be turbulence where the two fans meet which would not make the plane float, instead, i used fishing line to hold the paper airplane in place 1: if you draw a stick figure on a glassy, non pourous surface and apply water, the stickman will come to life and dance inside of the water bubble (only works with ethanol based ink. 2: fold a paper airplane and grab two fans, place the two fans on either side of the paper airplane and it will stay stagnant in its place 3: get you and your buddies to place their phones on a table surrounding a few kernels of pop corn, have the phones call each other and the energy output of the phones should pop the pop corn kernels because the phone produces a microwave and causes the kernels the pop. #3 is false although phones do produce microwaves, they do not have the power to pop popcorn, a standard microwave has about 900 wats of energy while a mobile phone only outputs about 1 watt of energy. round 3, here how to make a homemade glow stick, take liquid floor cleaner, a lollipop, for this, use a dum-dum since it has a different chemical bond which will react differently. get some dish soap and a little water, combine it all together and you get a bioluminescent liquid that glows in the dark #2: in Turkmenistan, there's a crater that is called the "gateway to hell," its a natural gas mine turned bad that the workers decided to set ablaze, and its still burning to this day from the 1970s #3 if you angle a needle correctly, it can pierce through glass and pop a balloon on the other side without breaking the glass #1 is fake, although we all could have wished to make a homemade glow stick, these chemicals cant be used to make it

[@Username-pb4xz]

Please do put the series name in the title, I can see fans of the series missing uploads. Maybe also use an indicator in the thumbnail, though that is extra.

[@788evets]

When it is gonna be the multiple are fake option?

[@Tyler_Skye77]

That's how you did it, cool.

[@ayartyom12]

Ya can connect directly to pencil,but must touch the lead one

[@englishmonkey3784]

A round 2

[@byeguyssry]

Wait why does the matchstick in the second question rise up?

[@jasonzervos]

Round 3, option A ISN'T FAKE?!?! My god!

[@rarebucko]

I picked C for the none were fake even though id seen something very similar done before because i thought the none were fake was just to throw people off, i got the rest lol

[@englishmonkey3784]

A or C Round 3

[@alstillplays]

Guessed them all correct the first time lmfao

[@TheGamerzYalove]

what website did he use?

[@pixelpuppy]

I like the "none are fake" only if I learn something cool and it's not obvious.

[@lobstervortex]

sporadically its really good, don't worry too much about the name

[@3possumsinatrenchcoat]

for all the jokes we made, no one was prepared for the long foretold arrival of the "no fakes" answer. you like playing the long game I see! :p

[@andrewprahst2529]

Can we get a "no one knows" option?

[@dtongy]

I LIKED THE NONE WERE FAKE!!!!!

[@idealicfool]

The oranges is the only 1 I know for certian is true

[@ziggys_stardust]

THIS IS THE FIRST TIME EVER I GOT THIS RIGHT. HALLELUJAH.

I GOT BAMBOOZLED

[@firelow]

I got the first and the second only, idk how to make slime so I thought it was fake

[@JaDroppingScience]

Haha normally when I mix a bunch of seemingly random stuff together, it is the fake one, so I don't blame you

[@pajasimelego]

I want to make that slime but do you need gloves for that?

[@milesparris4045]

You fooled me with the "None of these are fake" part.

Can Oranges power an LED?

[@rosagreensmith7351]

B?

[@Whiterhino11]

It would of been funny if he got to 1.99mil and Noone subscribed so right never get a raise😅

[@TheNorwellian]

Oh my lord I actually called it ? 1 seems like something I remember being true, 2nd one is something I actually knew and the third seemed like a thing that naturally happens so I was just thinking maybe none ? And I was right wow

[@darkenblade986]

i forgot none are fake was an option lol

[@nedwq]

More like 3 truths and 0 trashs

[@legoworks-cg5hk]

I got all of them correct

3/3

[@cubeninja1881]

bruh the non are fake, the first and second seemed ok, but when I saw third, I was like, oh I must be wrong aboutt he first

[@pettank2397]

The "none/multiple fake" options would be fair if you didn't preface the video with "two of the following videos are true while the other one is trash."

[@PridePrincess]

Round 1: Answer: B Round 2: Answer: C Round 3: Answer: C

[@D3M0N.77]

I don't like the No Video is fake option

Can oranges power an LED??????????????????????????? Also, I didn't know that that oranges could power an LED

[@50srefugee]

I like the occasional none/all were fake options.

[@luca._.gaming]

Ok but how tf does ice respawn the ink💀

[@hantrio4327]

Heat causes the ink molecules to change to a colourless compound. The reaction can be reversed at low temperatures and the colour reappears.

[@luca._.gaming]

@@hantrio4327 ok thanks!

B is fake, the circuit isn't closed. I have doubts about C, definitely possible, but with the right electrodes, it can work

B is fake. It pretends to reference the thermoelectric effect.

And before you were saying none of the videos were fake you, just said just kidding

[@SplatHeroYT]

Two of the following videos are true and the other one is true. There isn’t a fake to spot
