A Loud Bang

As a kid, I used to fold up a piece of paper a certain way to create a "paper banger" that would make a loud bang when I whipped the paper downward. I forgot how to fold the "paper banger," so I had to refresh my memory by looking at the instruction book from Professor Proton's Fun Lab kit. The kids had a lot of fun with their paper banger tonight. They kept telling my wife and I to pretend we were sleeping so they could make a big bang to wake us up. I warned them not to wake me up with any paper "bangs" when I slept. I hope I impressed on them the fact that my wife and I really did not want them running to our bedroom in the middle of the night to try out their "paper banger." We'll see.
