This is Zaina's Vacuum cup experiment. The method was ....
1. put a layor of water on the plate. 2. light the match and allow it to burn using a lemon slice to hold it straight. 3. Place the cup upside down over the match.
The air around the flame is pushed in all directions. Warmer air needs more space than cooler air! So, the air pushes under the small gap round the rim of the cup and lets the water in, pushing the water upwards!
How many water the cup can drink?
