Cool! We have those same cups where I work and I bet I can find a rubber band and paperclip, there, too! I intend to amaze my fellow cheese/coffee shop compatriots! Thanks, Hillar.

I gave away this cup shortly after making this video, then made another one and kept fooling around with it. I figured out how to make a chicken sound with it too, and will soon post another video demonstrating that.

Just after sundown this evening, I was next to a swamp with a bunch of frogs. I joined in with the frog call. Very strange! It felt as if I was part of a frog "drum circle"; a participant rather than just a listener. Lots of fun!
