A bulletproof vest. In case you think I’m joking, check this out:

Scientists at Nexia Biotechnologies in Montreal have discovered what happens when you cross a spider with a goat. The answer: a stronger bulletproof vest. The company has bred dairy goats with a spider in order to produce a unique protein. This protein will be extracted from the milk to produce silk fibers, called BioSteel, for bulletproof vests, medical supplies and space equipment.

I wonder if the goats now have eight legs?
