GRAVITY BONG MY FRIEND, take a 2 liter bottle of w/e and cut off the bottom about 2 inches up. then get a bucket fill it with water. take a spiece of tinfoil and place it over the mouth of the bottle, poke tiny holes and add ur dope, sink the bottle in the water up to the mouthpiece, but not up to the foil obv, light the shit and slowly start taking the bottle out of the water, when its almost completely out( u will see all the milky goodness forming inside) quickly take the foil off, put ur mouth to the mouthpiece of the bottle and suck in and push the bottle back down into the water.
