The kyykkä is a finnish word, in english it whould mean a gravity bong. You take a 1.5L plastic bottle (or smaller/bigger)and saw the bottom off, then you take folio paper and make a base (the base comes on the spot where you would normally have the cork), one needle and stick small holes in the folio. Now you will need a bucket, 10L(fill with water)is fine, and you put the bottle down the bucket, now put the folio base on top of the bottle. Insert your shit and light it up, smoothly pull the bottle upwards, and you will se the smoke going in the bottle. Dont pull the bottle to high, in this case the smoke whould escape the bottle. When the bottle is almost at the top, take off the folio base, and take the hit.
Tsekki lämyy ja kyykkää, se o riski
