Baking Soda and Vinegar Cannon

Air cannons are an iconic DIY project. Here at Make: we have featured potato cannons, T-shirt cannons, burrito blasters, taser activated cannons, and even a potato Gatling gun.

But in this project, we are doing something a little different. We are going to make a baking soda and vinegar cannon. This is very similar to the baking soda and vinegar volcanoes that we made as kids. I have just scaled up the reaction so that it can be used to send a potato flying through the air. Proceed at your own risk.
