Bullroarer

This week at Wood Tech we made bullroarers, a device that Australian Aborigines used to frighten the enemy before a battle. It makes a haunting sound that gets higher-pitched the more the edges are tapered.

We used a belt sander to shape our wood, which I don't know the dimensions of. We marked the hole for the string 15mm down from the top of our wood. A can was used for a smooth, accurate curve. After we sanded down the sides and drilled a hole, nylon string was tied through the hole. This bullroarer isn't mine, it's Nishnit's. Mine is on the roof because my string came undone...
