You have a bowl of water. Placed in the center of it is a paraffin candle. The water level is below the top of the wax by about a few milliliters. How can you use any ONE common household object so that when the candle is lit, the wick will go below the water level with the fire still going? A lighter is provided.
You can take any object with you; it doesn't matter. Light the candle and the wax will float up to the surface, protecting it from water enough so that it will melt below the water.
A few friends are enjoying their sea voyage in a boat full of apples. On the way, they felt hungry and thus decided to eat the apples. Together, they ate two dozen of apples. When they have eaten the apples, will there be any change in the water level?
If a five-hour candle and a six-hour candle were lit at the same time, how much time would elapse before one candle would be five times longer than the other?
