IPropose We Burn Money



Video:
http://video.about.com/chemistry/Burning-Money-Magic-Trick.htm

Materials:
  • dollar bill (higher denomination if you're brave)
  • tongs
  • matches or a lighter
  • salt
  • solution of 50% alcohol and 50% water
All you need is a bill, a mixture of water and alcohol, and a lighter. 70% rubbing alcohol works well. Alcohol burns blue and is a little hard to see, so if you want a bright yellow flame, you can mix a little salt into the alcohol solution.


1.Dip your money into the liquid and make sure it is completely wet.
2. Remove the bill, shake off the excess liquid, and ignite your money.
3.If the flame burns your hand, simply shake it out. You will need to soak the bill again in order to repeat the trick.

Precautions:
. Wear gloves and goggles

Scientific Principle
A combustion reaction occurs between alcohol and oxygen, producing heat and light (energy) and carbon dioxide and water.

I Propose That We Make Fireballs You Can Hold in Your Hand



http://www.wonderhowto.com/how-to-fireballs-can-hold-hand-110568/





The only materials needed are 100% cotton cloth, scissors, lighter fuel, cotton string, and a needle.

INSTRUCTIONS
  • 1. Thread the needle with cotton thread.

  • 2. Tightly roll the cotton strip into a ball.

  • 3. Pierce the ball with the needle and wrap the ball with the thread. End by running the needle through the ball one more time and break off the thread.

  • 4. Soak the ball with lighter fluid. Don't soak your hands.

  • 5. Don't ignite the the fireball while you are holding it. Set the ball on a fire-proof surface. I used a frying pan from the kitchen.

  • 6. If you want to hold the fireball, my recommendation is to pick it up with tongs and carefully/slowly set it on your hand. That way you'll be able to tell if you can take the heat or not. Once you gain some confidence, you can pick the fireball up using your fingers.
SAFETY PRECAUTIONS
. GOGGLES!

. GLOVES!

. It's best to use 100% cotton fabric and thread. If the fiber is synthetic (like nylon or polyester) it might burn or melt, with unpleasant consequences.

.The fireballs are reusable. Put them out when they run out of fuel or else the cotton will burn (you can tell this is happening when the ball starts to blacken and produce sooty smoke). If you get to the point where the cotton itself is burning, the fireball will be too hot to hold. Ideally you want to extinguish the fireball before it consumes all of its fuel. Simply soak it in more lighter fluid and relight it to reuse it.

Geekout!


The song of the day is Hello, I love you by The Doors. I've been reading a lot of comic books recently...I haven't been feeling like reading novels- which is kind of lame because I have a pile of books I really want to finish before I have to return them- oh well.... Comic books are just so good for some fun escapism...Superheroes are the modern equivalent of Ancient Greek Heroes, I find their stories so fascinating. Spider-man is the one I'm drawn to the most though...it's just so easy to relate to Peter Parker and his problems. I guess I'm so interested in Superheroes because I'm holding out for a hero myself...I've also been watching a lot of 90's television...namely Buffy the Vampire Slayer and Xena (Lucy Lawless is bad-a**!)
