Not since sharks with frickin’ lasers attached to their heads has someone done something so cool with light amplification by stimulated emission of radiation.  What’s totally awesome about this is they’re using such a modern technology to craft such an old-school weapon.

Speaking of old school – you can get one of these cool weapons for your classroom as well!

Pledge at the “Trebuchets for Schools!” reward level.

All of this extra money will be pooled and used to build trebuchets at $20 / each to give to science classrooms. We’re working with Marilyn Gardner at the American Association of Physics Teachers to find good homes for all of the kits we (and you!) donate.

Check it out, it’s for science!
