Siphons for AP General Siphon principles Place a hose into a tank of water, remove all the air out of the hose, block off one end of the hose (with a thumb) and bring it out and below the water level in the tank and remove the thumb – water flows from the tank until either end of the hose is above the water level then air enters the hose and siphoning action ceases – this is a basic siphon.
