Here is a way that you can prove to your friends that you control the Force! Take an ordinary can of soda or beer. Drink it so there is about a fourth of the liquid still in the can, and you can actually stand it on its corner and it will stay that way. So you tell your friends; "Watch me do my Jedi Mind Trick" and they'll all be like "Naw yo can't, you geek, etc, etc." Then, right before their eyes, balance the soda can on its side and leave it suspended that way with the power of your Jedi Mind! Your friends will be amazed!
