Candle and glass experiment
Children watch as the candle burns in air.
They cover the candle with a glass container. They wait and watch as the candle burns out without air! Thereby proving that fire burns only when air is present.
They pour shells one by one into a glass container to watch the bubbles appear as the shell touches the water surface and disturbs the air. Thereby proving that air is present in water!
Thats good one,, we also have this experiment in our school days and we also used to do it at homes...
