Mirror-Polished Japanese Foil Ball Challenge Crushed in a Hydraulic Press-What's Inside?

Published on Apr 10, 2018
In this video I make a Japanese polished foil ball by using aluminum foil and pounding with a hammer and then polishing until it becomes a solid metal polished ball! These polished foil balls started with a Japanese jeweler who made one that appeared to have no purpose, but the nation became obsessed with it and everyone started making them! You can see what's inside an aluminum foil ball when I crush it in my hydraulic press and see if the density increases or not.

  • Can speed of light or sound increase or decreased..

  • why does this channel get so many dislikes?

  • Silver burger patty looks like it

  • Put you or someone in the freezer lol

  • Heyy!!What all things do you have in your lab!? I like to see different instruments in diff videos...keep it up!

  • More alliuminal foil is what is inside.

  • Do you know how the aluminum circle comes?www.aluminium-circle.cn/ 😀😀😀

  • You need to go layer by layer on those balls. Not just bunch it so up then start hammering. It's supposed to be a slow process.

  • Why not just toss some in the dryer for a while? People use balls of foil as dryer balls. After enough loads, they get compressed into a compact, shiny ball from repeatedly whacking into the drum inside the dryer. Really only takes a few days of persistent laundry work. I’d never have enough patience to do it this way. Work smarter, not harder 👍

  • Foil *probably*

  • Can you destroy any type of matter?

  • Can you un burn ashes

  • Can you melt salt?

  • Is your hydraulic press powered by a machine gun

  • RIP Foil Ball (2018 to 2018) RIP

  • Hydraulic press: “OOOOOOOHHHHHHHWheeeeeeeeeeeeeeee”

  • Why you don't make a little real Tiny planet, with water & green water meterial I don't no what's it's say, green slippery meterial

  • that hydraulic press looks dodgy as

  • It is cool

  • 5:40 It can't feel heavier, it's still the same mass

  • Contract allegation mouse lock seven light change principal exceed funny exception fool.

  • It's possible to make sugar from sugar cane but is it possible to make sugar from sweet Mangoes?

  • All-oo-min-ee-um

  • Thiccness

  • Who noticed the compresser recoiled a little (Recoil:when I cant move)

  • Does he not know aluminium foil isn’t really made of aluminium?

  • This guy is such a Nerd

  • Tinfoil turned into metal ball and my microwave exploded it a lie dislike this video it lying dislike it >:/

  • u almost sound like pewipie

  • I hate the noise of sanding 😣

  • science oh mah god

  • Well here is one suggestion You should've put the puck in the water to see how dense it is instead of numbers just as you demonstrated it's buoyancy that's it otherwise good job.

  • If I had a press, I would have smashed it again. And again. And again. You're killing me Smalls, you're killing me.

  • i thought this was a video about a foil ball not math...

  • I was scared that it would become a black hole

  • I guess you can say you CRUSHED IT! 😆😅


  • Best polished Japanese Foil Ball!

  • Is it smooth

  • Its a lot less than half of the density, its actually less than a third as dense. Its 32% as dense, your math is way off lol.

  • Can you replicate a vinyl? I’d like to see if that’s possible?

  • I think I'm more impressed with your math skills than your skills in the shop

  • Lol

  • That is how they really to that ball thing.

  • What’s inside? Aluminum, probably.

  • Very Funni

  • Would a popcorn pop in a vacuum chamber? Please show us through an experiment.

  • Welcome to The king of Random channel

  • Hahahha da sound doh 4:44

  • 😍😍

  • downvote for cheating with power tools...

  • can you mix worlds heaviest gas and lightest liquid? will liquid float?

  • 3:00 You can tell who's the Physicist and who's the Mathematician because I though your owuld measure the diameter lol

  • Thousand dollars for cheap foil.

  • Its not a challenge!

  • Well sir I guess you just invented high resistance material for less density? Congratulations on your invention 😄

  • 0.85 is a little less than half of 2.7? Wow... strong math skills there buddy.

  • You crushed your hard work >.> Nah just kidding this was suppose to be a challenge.

  • You should make a spherical mold for the press and pump these out like crazy

  • Just imagine theres a death sentence that squishes the prisoner in a room that uses a hydraulic press for a ceiling.

  • All the hard work and it got crushed

  • All u have to do to get viewers is crush, smash, melt, or etc.

  • I laughed too hard when it floated🤣😂🤣😂

  • That math gave me a headache. Cool demo though.

  • How’s it half as dense when the ball’s density is 0.87 and the actual alluminum is 2.7?

  • Interesting I'm gon try this but in have all that fancy stuff lol

  • Will it change it color after heating

  • Man u talk a lot shut the fuck up

  • I dont feel like leaving a comment because i want to finish watching more vids from your channel but just wanted to say keep up the great work 😀

  • 4:42 Am I the only won that heard "Weee" in that thing

  • Math yay

  • The original creator of the foil ball, only used a hammer.

  • i made it and the easy way is sandpaper and polishin cream

  • Bro put slime in vacuum chamber

  • now that makes me wanna turn it into a shiny coin

  • baitola\

  • I think it would work with gold foil - try it.

  • これ日本人が最初だったの!知らなかったwこの人面白い🤣

  • Did bobby duke do one of these

  • Shiny coaster

  • hammer it more it actually sinks i tested it out

  • Your voice tho. Reminds of Sheldon and hiccup from how to train you dragons

  • what happens if you just take a bunch of layers of aluminum sheets and press it?


  • The hydraulic struggled for a couple seconds to crush the ball

  • I thought you was gonna like uh shape it with the uh hypduail press bruh.

  • 1:22 polish uh how.

  • Wait it's a like uh channelage huh.

  • When you break that countertop, wifey gonna be P!!!!!$$ed.


  • Anyone here from Sarah from BuzzFeed?

  • When a scientist makes a polished aluminium ball

  • But it’s not aluminum, it’s tin.

  • 4:00 that sounds just like MC Mental

  • make a dumb project

  • Does it float after the press?
