Did you know if you feed a crab alcohol, it'll walk straight forward, instead of side to side? (not sure if it's 100% true)

Did you also know if you make a crab walk in constant circles, the same thing will happen as stated above?

Did you know that if you give a spider caffiene, it won't make a nice clean web, but it'll look all deformed and confusing?

what interesting random facts do you know?
