Desktop Trebuchet that Launches Ping Pong Balls
The Ballistic Trebuchet is a working wooden model of a medieval siege engine, built from 158 laser cut plywood parts and standing 320 x 130 x 210 mm on a desk. A rubber band drives the throwing arm, so the model launches the five table tennis balls in the box without batteries or electronics.

How the Trebuchet Model Works
- Elastic drive: a tensioned band swings the long throwing arm, the same lever principle medieval engineers used with a counterweight
- Guide rail: the shaped barrel channel keeps each ping pong ball on a repeatable path so shots group tightly
- Adjustable release: changing the tension and the release stop alters range, which is the physics lesson built into the kit
- Trigger and winch: a hand wound cord and catch let you cock the arm and fire it in a controlled way
- Five balls included: the set ships with table tennis balls for indoor target practice at cups or paper targets

Specifications
- Assembled size: 320 x 130 x 210 mm (12.6 x 5.1 x 8.3 in)
- Part count: 158 laser cut wooden pieces
- Assembly time: about 3 hours
- Power: rubber band tension, no batteries required
- Included: pre cut wooden sheets, fittings, cord and 5 table tennis balls
- Recommended age: 14 and up, younger builders with adult help
A STEM Model Kit for Medieval Engineering Fans
The parts push out of pre cut sheets and slot together, so the build itself teaches how the frame, axle and throwing arm transfer force. History and physics classrooms use the same trebuchet layout to demonstrate levers, stored energy and projectile arcs.
Finished, it works as desk decor for engineers, a history buff gift and a hands on birthday or Christmas present for teens and adults who build mechanical wooden models. Aim it at soft targets and keep it clear of people, pets and glassware.
