Ok Where does the wind come from?
hahaha
Turn on the lamp, and let it heat up a bit.
Sprinkle some talcum powder just above the bulb. What happens? What might be some reasons?
(The heat from the light bulb warms the air around it. As the heat rises, it takes the talcum powder with it. In real life, as the sun heats the air just above it also heat up. This hot air expands and becomes lighter; that's why it rises. Cold air moves in the now warm air's place, and this movement of air is wind.)
why is yawning contagious?
