Prince Rupert’s Drops are just molten glass dropped into a bucket of ice water, where they form tadpole like shapes. Nothing too exciting so far…

But, as they cool so rapidly, the external area in contact with the icy water goes under super-high compression, which makes ‘em tough. And what happens when you break that tension? Find out!

There’s a video showing the fun part in more detail here.

Thank you, StumbleUpon! =D
