Pinecone Catapult

Miles and I spent Saturday building a PVC catapult for hucking pinecones. Started with inspiration from some YouTube videos, but scaled up and modified designs we found there. Capable of throwing a pine cone around 45 feet with a single bungie! Spent around $25 on parts. Build time ~3 hours. Considering adding a second bungie for extra distance, but don’t want to make it too strenuous for the kiddos.

Working with PVC is great – cuts like butter with a chopsaw, pieces slip together like Legos. In fact, the fit is snug enough that we’re not gluing it for now -nice to be able to disassemble for storage.

Finding the perfect throwing cup was the biggest challenge. Considered sewer pipe caps, chopped down paint mixing buckets, and tupperware, before deciding on this perfectly sized electrical junction box. Unfortunately it had a metal plate riveted to the back, which I had to hacksaw off – easily the hardest part of the build.

See full-size images and captions at the Flickr set (captions not available in embedded slideshow).

Shot some video too, but did that dumb thing where you record when you think you’re paused and pause when you think you’re recording. D’oh! Will try the video again later.

Catapult is available for rental for birthday parties and bar mitzvahs.
