What Is It? game 219

Once again, it's time for our collaboration with the always amusing What Is It? Blog. Do you know what the pictured item is? Can you make a wild and ridiculous guess?

Place your guess in the comment section below. One guess per comment, please, though you can enter as many as you'd like. Post no URLs or weblinks, as doing so will forfeit your entry. Two winners: the first correct guess and the funniest (albeit ultimately wrong) guess will win T-shirt from the NeatoShop.

Please write your T-shirt selection alongside your guess. If you don't include a selection, you forfeit the prize, okay? May we suggest the Science T-Shirt, Funny T-Shirt and Artist-Designed T-Shirts?

For more clues, check out the What Is It? Blog. Good luck!

Update: the mystery object is a simple ice cube crusher. The first with that answer was just a guess, who wins a t-shirt! The funniest answer came from upiru, who said, "It’s a chewing-gum tester of course. Some clever students even use it to chew their gum discretly under the classroom table." That's good for a shirt, too! Congratulations, and thanks to everyone who played along. See the answers to all the mystery items of the week at the What Is It? blog.
