Build your own medieval siege engine from pre-drilled planks, a little glue and the help of easy, step-by-step "blueprint" instructions. Then let the fun and experimentation begin! What travels farther: a marshmallow or a piece of macaroni? Alter the counterweight to adjust the trebuchet's hurl, and practice knocking down a field of target planks using the two included balls.
Keva products encourage curious young engineers-to-be to explore different ways to build structures and machines. This kit is part of their Contraptions line, but you can also get basic Keva building planks to extend the fun!
