How to Build a Working Train Whistle out of Paper!

Sweet! This project is totally doable with household materials (printer, paper, thicker paper, white glue, scissors, and a razor edge). Just print out these paper parts, fold, cut, glue, and after 3 hours (including drying time) you will have a playable train whistle. I used regular printer paper for the bellows and a thicker, sketch-book paper for the pipes and other parts. The sound that the whistle produces is what you would expect from a mini paper organ - soft and simple but very amusing! Edit: and *cute*!

Paper machines are awesome and fun to make. Check out Paper Automata and How to make a working paper clock.

I just ordered the paper pipe organ kit so I will keep you posted with how that works out. Please subscribe to the rss feed to stay updated.
