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.

  • You pronounced Aluminium wrong

  • No

  • Cool

  • That's the difference between here in the U.S. in Japan. In Japan, the challenge is to make shiny, perfectly spherical balls out of foil. Here in the states, teenagers eat detergent. That's why Japan has less than 10 gun deaths a year, and here, Trump is president.

  • What a complete waste of time!! and foil!!!!

  • 3:30 that's actually just under a third. It's misleading to say just under half

  • Exelcelente Vídeo

  • Dad make my little picture pretty, my son

  • What if you made a cube shaped mold and use a hydraulic press? Would that be able to crush the aluminum foil down into a solid aluminum cube?

  • You have to factor in the fact that there's a lot of aluminum oxide because there are many layers where each layer has oxidated. Aluminum oxide is of course heavier than aluminum oxide, so it throws your calculatons off.

  • Cool!

  • My hypothesis is that the ball would just get in a weird shape after it is crushed in the hydraulic press. That is because aluminum is a malleable metal.

  • What if you cook an egg then you blend it till liquid then cook it again

  • I can NEVER do dat

  • Hi you are very good

  • It doesn't look at all like on the image of the video!! So you're lying!

  • How did you do it i just wanted to have it

  • Mirror foil ball = fidget spinners !!!!!

  • “About half as dense” not even close bud. .85 X 2 = 1.7 which is nowhere close to 2.7

  • Markrichardson155@yahoo.com

  • I want to try this like so bad! Should I try it?



  • It's not a solid ball of aluminum. No matter what you do, simply forming it into a ball shape does not bind the compounds back together to make it solid. It was always going to break apart easily. The fact you called it a solid ball at all, shows your incompetence.

  • The crusher sounds like a shot gun

  • I love this

  • It is very entertaining

  • maybe it floats...because air pockets???

  • I hate it when he says Aluminium

  • It became a pancake

  • « a little less than half as dense as real aluminium » yeah because 2,7/0,85 = 2 clearly. And I think at the end your measurements are not as precise as your results suggest

  • Why do you even question if this is solid Aluminium, you can clearly see the discrepancies in the surface of the object.

  • i like your video's but if to could talk a bit less it would be good..you just talk many things that make no sense or you just talk a lot that dont need to be..wish if you could talk less and make it simple and meanings

  • Have you nothing better to do ? Wanker

  • 4:43 When you fart

  • Have a question how much to foil will I needTo make A tinfoil ball?

  • How to get views in 2018 in 2017 it was all about the fidget toys

  • Best one I’ve seen 👍

  • Imagine tgat ball is earth. Now squash it. Great all flat earth theroes are true.

  • I NEVER thought this would work.

  • Why are you all haters this is soo satisfying

  • can you do the 1000 degree knife again

  • it’s a hamburger patty

  • rip all the hard work

  • Que dijo???!!!!

  • Polska mowi ze chujowe

  • Now it can be a cup thing I forget what it's called

  • Could you make a aluminum ball using the press?

  • hey masturbator plz make some videos about your fitness

  • dont be a nerd

  • What inside foil😂😂😂

  • Could you polish the disc?

  • You own a hydraulic press but not a set of measuring calipers?

  • "a little less than half".... it is much closer to a quarter than it is to half.

  • That's not how you actually make the ball FYI😊😊😊

  • 13 on trending OHYEAH

  • Last night i fell asleep to this vid lmao

  • It’s a floater

  • should have tried compressing it into a cube :D

  • This is American science at its highest level.

  • الي عربي لايك ومن السعودية لايك

  • Boring

  • Pneumatic press... Not hydraulic

  • it's feeling a lot more hefty now..... uh... it's the same mass it was before you crushed it....

  • All that hard work

  • People are really interested in this?

  • Tape measurement at last..? No way man.....

  • 你该有多无聊

  • My dad also made his self a gold chain for r necklace or

  • My dad makes medale with part of a fire sparkler or a bone or a rock and youses fire for one of those and peace’s of medal come out then my dad puts it together then he makes a lot of money

  • Ats easy how the make even not with uluminum foil you can youse a bone a rock or even some part of a fire sparkler

  • gfg

  • It is real aluminium, just leses dense than a solid volume of aluminium of the same size

  • Now take a solid aluminum ball and make thin sheets out of it suitable for wrapping left over food.

  • Such a click bait

  • God this clickbait 😝

  • This is funny, we used to do this in the early 90's with the aluminum foil from cigarette packs... this really isn't new lol... and I'm pretty sure it wasn't knew when we were doing it in the 90's either...
