Detailed explanation-2: -1) Take a plastic water bottle and fill it with water to its half way. 2) Place a straw into its neck part and seal the leaky edges using putty or clay. 3) Blow heavily into the straw which creates increased air pressure inside the bottle.

Detailed explanation-3: -Once the glass is standing on the plate, the burning candle uses up all the available oxygen in the glass, then goes out. As it does so, the air in the glass cools, and as it cools, the air pressure in the glass falls below atmospheric pressure. Water is drawn into the glass until the pressure is equalised.

Detailed explanation-4: -What happens if you cover a lit candle in a water basin with a glass? The glass becomes foggy on the inside and the flame fades and eventually goes out. Then the water level in the glass rises. The burning candle produces carbon dioxide and water in the form of water vapor.

Detailed explanation-5: -Experiment: Cover a burning candle with a pitcher so that the candle is in an air-tight room sealed by the water at the ground. Observations: After some time, the candle dims and goes out. Just before the candle dies, the water level rises to almost 1/10 th of pitcher height. No air bubbles are seen.
