Exploding glass

Materials science can be fascinating. Take glass for example. Apparently, whn molten glass is dropped into cold water, the drop becomes incredibly hard. So hard that it is nearly impossible to break it. However, the tail of the drop acts similarly to detonation cord on a stick of dynamite! One little nick and the whole drop explodes in a shower of tiny glass fragments.

Dustin of YouTube channel 'Smarter Every Day' (one of the coolest channels out there, and my new favorite) explains the whole process with high speed video captures, fun graphics, and easy to understand explanations.
