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!
