OUT
5 US GAL
. valve.
/ / Mouth piece and bowl you need to make
water level // a bowl you can pop out quickly and the
/ mouth piece needs to be flexible like a
5 US GAL piece of garden hose
IN
PUMP hole near bottom
You need to bore a hole in the side for the intake hose and
bore a hole in the top one for the output hose of the pump
You fill the bowl with weed and place it in the mouth piece, turning on the
pump will displace all the water from the bottom into the top creating a
suction at the mouth piece. light the bowl when the pump is moving the water
and the bottom will fill with smoke. Since you have a valve the water wont
just fall back into the bottom jug. remove the bowl and put your mouth up
to the piece, turn the valve and all 5 gallons of water will drop at once
displacing all 5 gallons of smoke at once into your lungs.
