Red Bull (Aka death and great for trolling) by lunaglimmer

Red Bull Gives you Wings!

Ps Side effects are: Halluciation, uncontrollable muscles, being ugly, and instant death

Great for trolling your friends it looks like the best potion ever but if drunk will kill you instantly (when you try to respawn it wont work so go back to title screen,join server or world again and then respawn will work)
