Today's experiment is: the experiment is also a........prank!
Experiment :poke a pushpin in the middle of a drinking straw. poke as many holes as you can.but, do not poke them very near to each other.put the straw in a cup half full with water. when your friend says that he is thirsty, give him the cup. He won' be able to suck up the water easily!
