There's nothing quite like loading up a siege engine and lobbing stuff -- balls, coins, very small rocks -- across the yard. Any kid would relish the experience, right? That's what Evan Murphy and Michael Woods thought when they designed their miniature plywood trebuchet, so they're not just running a Kickstarter drive to sell their one-foot-high laser-cut snap-together model to enthusiasts -- they're also taking donations so they can give trebuchet kits to schools. And unlike a lot of other treb models, theirs has an adjustable throwing arm so you can play with the length of the arm and the location of the counterweight and actually learn some physics.
The Kickstarter drive runs until midnight on Thursday, April 21, so there's still time to jump in.
