Investigate physics using technology from medieval times! Build six sleek, updated models of catapults, trebuchets, and other medieval launchers. These classic siege weapons from the middle ages also happen to be great tools for teaching physics, including lessons in force, energy, motion, and projectiles.

A catapult is a medieval ballistic device that uses mechanical rubber bands and counterweights to fling projectiles — in this case, foam balls — into the air. The 32-page, full-color manual has illustrated step-by-step instructions for building the models and conducting the experiments.

Bonus: Also includes folded cardboard blocks so you can build a pretend castle wall and see if you can knock it down.

Natalie ★★★★★

My son and I spent a whole weekend building the trebuchet, and watching it actually launch projectiles across the yard was way more satisfying than I expected. The six models give you a great variety, and the updated designs feel sturdy enough to handle real use.

Natalie U. ★★★★★

The instructions are incredibly clear, and my son had all six models built and launching across the living room within an afternoon. It's a fantastic way to sneak some physics lessons into playtime without it feeling like schoolwork.

Andrew ★★★★☆

I've always been fascinated by medieval siege engines, and this kit delivers on that interest. The trebuchet model is particularly well-designed and really demonstrates the physics of counterweight launching. My only wish is that it included more historical background on each weapon type.
