You will need
  • ethyl alcohol, dry boric acid, a drop of sulphuric or hydrochloric acid.
Prepare the basis on which will be applied to the mixture. Apply the solution directly on the hands is bad enough. It is for this reason, you should make small sticks or balls, which could cause a fire.
Take a thick woolen thread and wind a small ball. 2-3 cm of the coil will be enough for 2-4 minutes to see a cold burning. To make a kind of torch, wrap the thread on the needle or pencil.
Prepare the ingredients for the fire. Operation is desirable to produce quickly and accurately, so try to have everything at hand and you have easy access to all components of the composition of the flame. Watch out to avoid early confusion, since you are working with very complex and hazardous substances.
Take a small Cup and pour into it a tablespoon of alcohol. Then add the dry boric acid (also spoon) and add one drop of sulphuric or hydrochloric acid. Be careful in proportions. The desire to make a "brighter" can lead to poisoning and other negative consequences.
Preheat the resulting mixture. The safest way is by means of steam. 2-3 minutes for a couple would be sufficient. Try it with a fingertip, if the skin suffers, then everything is fine.
Be careful. Once you soak the ball and set it on fire, starts to burn boric acid. It will not burn and significantly, even to warm his hands. But be prepared that as soon as the boron burns out, will start to burn alcohol, and its flame is quite noticeable.
