As shown in the figure here, make a paper pot wjth the heip of the clips. Now fill it with water and burn a candle under it. Be carefui about one thing. The flame should not reach that part of the pot which is untouched by water.
After some time, the water will start boiling without burning the paper. How does it happen? In fact the water takes away ail the heat before the paper can reach its burning point. The water boils at 212°F and at this temperature it gets converted into steam. And as the temperature doesn't go above it, the pot can't reach its ignition point which is much higher than the boiling point of water.
