Take a Pepsi can and lay in on it's side. Then put a dent in it and poke some holes and make it able to hold a good sized bowl. After that, you poke a carb into the side of the soda can.
After it is made, you load it and take three lighters (typically red, white, and blue like the Pepsi can) and light them all at once like you would with a cross joint. Smoke the entire contents of the bowl you loaded in one hit.
