PressTube, one of the challengers to the Hydraulic Press Channel throne, just took the science angle up a notch. Eschewing household items, they went for everyone's favorite scientific wonder, the Prince Rupert's Drop.

Prince Rupert's Drops are a bead of molten glass rapidly cooled as they fall into water. The resulting crystal structure makes them nearly indestructible--unless you crack the tiny, delicate tail in some way.

Needless to say, crushing one under a hydraulic press without damaging the tiny hair-like tail was a challenge, but these guys took it head on. Props, PressTube.
