Money on Fire

How can we burn money without destroying it?

[Figure1]

Have you ever heard the expression people burning money?  It figuratively means to spend all your money.  Another meaning of this expression is literal - people actually setting money on fire. Burning money is one example of a combustion reaction, and frankly, burning money is such a waste when you could spend it.  Instead, we can put evaporation into action, burn money and still spend the money. (Kids, don’t try this at home without an adult).

Creative Applications

  1. What allows the fire to burn? (Hint: What did you douse it in?  What do all fires need?)
  2. Why did the dollar not burn into ashes?
  3. Why did the dollar feel damp? (Hint: temperature of  evaporation of water/alcohol)

  4. Do you think this process works outside of money, like on clothes? (Kids, don’t try this at home!)
