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.

  • Hi Action Lab. DId you ever considered making a video about overheated water in a microwave? Using very clean distilled water and a very clean cup so the water doesn't boil but as soon as you add sugar or something it will shut off. (demonstrating the danger of overheating water)
