What kind of part is it?!

I'm a 13-year-old Korean fan, and I have an idea for a brick experiment channel. Anyway, guess what part that is. No deleting or editing allowed, and you only get one chance. I'll tell you the answer tomorrow, and whoever gets it right, I'll teach you how to build it. Got it?! submitted by /u/The_13yo_Master [link] [comments]
