Remember the video clip of the guy dropping a red hot nickel ball onto stuff?
We've featured a clip where the red hot nickel ball is put on top of a block of ice, but Youtube user carsandwater has put said nickel ball on things like meat, ballistic gelatin, a cup of water (nice!), watermelon and so on.
But the red hot nickel ball has finally found its match: a blob of Aerogel, the lightest man-made solid composed of 99.98% air is such an excellent insulator that the nickel ball did nothing to it!
Bonus: What would happen if you put the red hot nickel ball onto a bowl of pop rocks? Well, wonder no more!
