Burning money?! I'd rather use them!

Like it. Loathe it. Want it. Waste it. But you just cannot ignore it. That rumpled piece of printed-paper in your wallet that the world bows to its power, that's money.






They say money holds the key to happiness. I'll leave that to you to decide. If so, who actually even thought of burning money? That must sound crazy to you, but this is true. This is one neat magic trick that will blow your mind!

(Do you remember this scene from The Batman movie? :D )


So, this is what you will need :
  • dollar bill ( higher denomination for the dare devils)
  • lighter
  • salt (for a coloured flame)
  • solution of 50% alcohol and 50% water
  • tongs
Next,
  1. Prepare the alcohol and water solution.
  2. To aid in producing a visible flame, add a little salt to the solution of acohol and water.
  3. Soak the dollar bill into the solution. Make sure it is thoroughly wet.
  4. Pick up the bill with a pair of tongs, not your hands. Drain away the excess liquid then move away from the solution of alchohol and water.
  5. Here's the interesting part. Light the bill up on fire, and the flame should go out after a while. What do you see???
C2H5OH + 4OH ---> 2CO2 + 3H2O + energy


Heat, light (energy), carbon dioxide and water is produced when combustion occurs between alcohol and water. The material of a bill is more like fabric than paper and alcohol has high vapour pressure. So, when the bill is soaked in a solution of alcohol + water, the alcohol mainly soaks only the outside of the bill material. It is actually the alcohol being burnt, when the bill is lit. The temperature at which alcohol burns is not high enough to evaporate water( and water has high specific heat capacity). This is why the bill remains wet and not caught on fire. You will get a slightly damp dollar bill, when alcohol is burnt and the flame goes out! Awesome!

Dare try it? :D
