Now it's time for our collaboration with the awesome What Is It? Blog! What is this thing? You don't have to know to win!
Place your guess in the comment section below. One guess per comment, please, though you can enter as many as you'd like. You might know the true answer, but we're going to select two winners who come up with the funniest, most outlandish guesses to win a T-shirt from the NeatoShop. However...
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?
Please note that the cut-away view is for instructional purposes, and the original object is as it appears in the top picture. Get more clues at the What Is It? Blog. Good luck!
Update: the pictured item is a fusible plug for a boiler. If the temperature gets too hot, the tin plug in the middle will melt and release pressure. There's a more detailed explanation at the What is It? blog, but we were looking for humorous answers this week. Ladybugs got a few hearts for her answer: "It's the loose screw of the U.S. Congress in dealing with the budget crises." Makes perfect sense! And Chris Stevens had good one, too: "The holidays are coming, and Iron Man has been known to spend a little too much time at the buffet. Sometimes the suit needs to be "let out" a little, and these babies are just the hardware to do it!" Those both win a t-shirt from the NeatoShop! Thanks to everyone who played, and thanks to the What Is It? blog.
