Learning takes on a whole new trajectory with the KEVA Catapult! Kids can build their own medieval siege engine with pre-drilled KEVA planks, a little glue and the help of easy, step-by-step "blueprint" instructions. Then let the fun and experimentation begin! The Catapult allows you to test launch distance by adjusting the arm recoil or the height of the flight deck. Everything you need to build the Catapult is in the box, no tools required! Finished size measures over 14" tall!Recommended Ages: 8 Years And UpUse: IndoorMeasurements: 8.5 Length/Inches, 3 Height/Inches, 8.5 Width/InchesBase Material: 95% Cardboard, 5% Other 5% Or LessCare: Wipe CleanCountry of Origin: Imported
