If the paper begins to actually burn, quickly drop it into the container of normal water. If the paper lit on fire without burning, try the experiment with real money. The process is the same as with the paper. Soak it in the solution. Using the tongs hold the money over the candle until the alcohol catches fire. If it begins to actually burn, quickly place it in the water container.
If your mixture is right, though, the alcohol should burn on the surface while the water keeps the actual money from burning. The alcohol will eventually burn off on its own or you can dip it into the normal water to put the fire out. Now comes the awesome part. The same process can be used to light your hand on fire. It works best if you use rubber gloves, but you can use your bare hand as well. Test paper before using your hand to ensure the alcohol and water are at the correct percentage.
Follow the same procedure as with the paper and the money. Put on the rubber gloves and dip your hands in the solution getting them as wet as possible. Then hold your hands over the flame until your hands catch fire.
Hands on Fire Trick
The fire will begin to get hot on your hands. Make sure there is a container of normal water nearby so that you can put the fire out if it gets too hot. You can also wave your hands up and down quickly to put out the flames. The trick with this experiment is all about science, not magic. Alcohol has a high vapor pressure, so the vapor is concentrated above the liquid on the surface of the object.
The alcohol burns, not the water or the object that has been soaked. Alcohol also burns at a low relative temperature which is not high enough to evaporate the water. Thus, the water acts as insulation on the object preventing it from catching on fire.
You may have noticed that the paper has a tendency to burn faster than the money when all of the alcohol has burnt away. This is because money is made of cottony material and does not burn as easily as paper does. Adding salt in the experiment serves two functions.europeschool.com.ua/profiles/gehowyzyb/hombres-solteros-de-40.php

First, it alters the color of the flame making it more visible. Alcohol by itself burns a faint, light blue color. The salt also causes the alcohol and the water to separate in the mixture adding more protection for the object. If you want to take pictures of the experiment, they will show up best at night or in a darkened room. Keep the flash off. The color of the flame won't show up with flash.

My alcohol flame experiments were to see if a "trick" firewalk could be devised.
After testing the relative temperatures of the different alcohol mixes and successfully walking through a pool of the burning fuel in shorts and bare feet I had the fire part figured out. The setup is simple: rake the sand into into a bed about 2 inches thick, and 6 feet long on a wet grassy area at night. Pour and spread out the granite out to cover the sand and wet it down well to keep the rocks from becoming too hot About 1 gallon of the fuel mix will be needed be sure to add salt to make a nice orange flame. When ready, pour the fuel in a zigzag pattern from one end of the bed to the other the sand helps absorb and keep it there.
The zigzagging is important to give your feet a chance to cool off between steps the flames are still very hot.

Make sure the area around the pile is really watered well, both to contain the fire and provide a spot to step if the heat becomes too much. Light the fuel it looks convincingly menacing and take a walk. You'll find the hard, slightly sharp rocks cause you to walk as if you were actually walking on coals Be sure not to wear long pants or loose clothing and keep a water hose ready just in case.
The rocks will eventually become very hot. If you can hear the water sizzling, and the rocks become dry, its time to stop. Couple of notes on the different alcohols available: Ethanol or denatured alcohol burns with the coolest flame, isopropyl rubbing alcohol burns a bit hotter and has a penetrating odor. Methanol is in a class by itself. First and foremost it is extremely poisonous and can be absorbed through the skin so it is NOT advised for fire tricks.
It also burns with the hottest flame, so even diluted with water it is the one most likely to burn you all other things being equal. It will also still burn with a ton of water added to it.

Interesting thing about all alcohols is they all burn with a very hot flame. It is the water that keeps whatever it is you are using for the trick cool. One way to make the flames bigger is to use warm water in the mix. It will cause faster vaporization of the alcohol. The downside is that the water will heat up that much faster during the burn water above 60 degrees is enough to scald you. Barium chloride will produce a deep green, strontium chloride makes a brilliant red.
Both are fairly non-toxic. One thing to keep in mind that I found out the hard way besides taking the hair off my lower legs is that if you turn the alcohol soaked surface downward, the flames will lick up the sides. I was able to walk through puddles of the burning mix barefoot pretty comfortably, but once I wore flip flops and the flames rolled up along the front and sides under my DRY feet.
The flames themselves are really hot! Interesting thing happened when I tried making a pool of fire about 6 feet around and walked through it I only shorts and bare feet. My feet were fine, but it burned all the hair off my legs about 10 inches up. Makes sense since my legs were not wet but my feet were. It can if the fire burns on it too long. You may need more water in your mixture to help insulate better. Heyhey - It would be very dangerous to do that. You wouldn't be able to control the fire and it could burn through your clothes and severely burn your skin.
Watch videos of stuntmen who are on fire. There is always a team of people ready to spray them with extinguishers as quickly as possible. I am doing this with money for my AP chemistry class, and it looks awesome You could try spraying the rope with flame retardant, but it may make it so the rope won't burn at all. Other than that, just let the flame burn just until the point when the rope itself starts to catch fire.
Jason - No, as long as you put out the fire when your hands start to get too warm. That's the point when the water has burned off. Sharkye11 - My husband does this trick for Halloween every year. The kids love it. You can even use the alcohol without adding water, but it will burn and start to get hot much quicker.

Now that is a cool trick! This would be so awesome to use on Halloween or at one of our fundraising events for a little extra show!
Thanks for the idea and the formula! Tristin - There was a typo in the mixture.
It was supposed to be a 10 instead of a 7. It's fixed now. You should definitely edit your math on the mixture. Playing with fire can be scary, but if you use safety precautions it can be relatively safe. Very cool and thorough. You gave readers confidence in a normally scary thing.
Great hub. It is just a common household ingredient that is relatively safe to use. Chemicals that burn with low relative temperatures are likely to work as well. They might be dangerous to experiment with, though. ConorJ - You can use your bare hands and light them on fire.
