Boost Your WiFi Signal With A Beer Can

WikiHow has the complete instructions, but basically what you do is cut the bottom off a beer can, slice down the middle of the side, then cut between the top and the sides almost all the way but leaving an inch so the side is still connected to the top. Then you pry open the sides of the can into a radar shape. Stick the antennae through the hole and point the wings so they open out into the room and boom, more wifi signal.
