Ages: 9 - 16
A little messy
Cut one of the straws at an angle just below the bendy part. Discard the bendy piece.
Pinch the angled end and slide it into the short end of the other straw.
Tape the straws together. Wrap the tape around several times to make a good seal.
Insert the taped side of your siphon in the bottle. Place an empty cup next to the bottle.
Such water into the straw. Keep your mouth on the straw and bend it down. Make sure the end of the straw is below the level of the water in the bottle. The straw should be full of water.
Release the suction and let the water flow. Watch your siphon drain the bottle into the cup!
