==Description==
A paper cup alone burns when put in contact with a flame; a paper cup filled with water won't.

==Equipment==
* Paper cups
* Flame source (torch, candle, lighter, etc)
* Water
* Support with clamps

==Instructions==
* Install the paper cup over a flame.
* (Optional) Burn the first paper cup without water to show it is indeed flammable.
* Put water in the (second) cup and light the candle/torch.
* Wait for the water to boil

Note: The cup with water may burn a little depending on its design but what is actually containing the water won't burn.
