Break the glass in a whole new way with a Prince Rupert's Drop

Val and Galen's science tendencies led them to a really interesting and symbolic unity ceremony. They created what's called a Prince Rupert's Drop.

I'm sure some of you academics out there know what's up with this, but I had to take to Wikipedia to see what the hell this was all about (since my head jumped to a piercing I won't mention).

Here's what Val said about it:

If you drop molten glass into water, it cools very quickly but has lots of residual stresses inside. It's very strong under compression (you can't break it with a hammer), but if you snap off just the tail, the whole thing explodes in a shower of tiny glass powder.

They ended up breaking this in lieu of the traditional Jewish breaking of the glass. I kind of love the symbolism of such a hard structure with such a fragile mechanism. Plus, SCIENCE! If you want to attempt this at your ceremony, just make sure to find a helpful scientist or science teacher to make it happen safely.

And check this shit out: these guys over at Smarter Every Day decided to film a slo-mo version of this kind of drop with a high frame rate camera. At 2:31 it turns into what looks like an explosion of rainbow confetti! Plus, they totally explain the science behind it for our braining pleasure.

  1. Whoa, seriously awesome. Boy and I are science geeks and I'm sure I could convince him to do this when we get married. Way cooler than stepping on a shot glass.
