70% rubbing alcohol is a high concentration. If you can’t find a lower concentration, dilute it to make a mixture that is one part water, 2 parts 70% rubbing alcohol.
If you did use gloves to soak the cotton ball in the rubbing alcohol, take off the gloves, making sure not to transfer the rubbing alcohol to your hands. Your cotton ball is now ready to be set aflame!
Make sure that you are using a T-shirt that is 100% cotton. If you use a shirt that is only partly cotton, it will melt instead of burn.
Keep holding the cloth ball in your hand after rolling so that it doesn’t unravel.
Make sure that the string you are using is 100% cotton. Hold the ball while you pierce it with the needle to make sure it stays together.
Don’t break off the string, as you will keep using it.
Do not get any rubbing alcohol on your hands or clothes.
Make the transfer after only a few seconds so that the cloth ball doesn’t soak for too long. If the ball absorbs too much rubbing alcohol, it will become soaked and start dripping. This can be dangerous when you light it on fire.
Having rubbing alcohol on your clothes can cause your clothes to get set on fire.
Review how to use the fire extinguisher before lighting the fireball.
Clear the bowl of rubbing alcohol away, as it could be a fire hazard.
If you do drop the fireball, you can try to scoop it up, or just stamp on it with your foot to put it out.
Hold your hands away from your body so that there is no risk of the fireball catching your clothes on fire. Remember not to panic. It’s safe to hold the fireball as long as you keep shifting it around and keep it away from your clothing.
