That's right, tonight I'm giving a demonstration speech and my subject is "Playing WIth Your Food- or, How to Build a Potato Cannon. I have a new cannon all cut to size and an ignitor already epoxied into the combustion chamber. So tonight I'm going to explain what potato guns are, show how to assemble one and play a short video of a potato gun in action.
Our instructor really shouldn't let us pick our subject matter without some oversight! Anyway, it should be lots of fun.
