Start a campfire to keep you and your friends warm
Have you ever gone camping with your friends and forgotten the tools you need to start a fire? Well, why you would leave a fire starter behind but remember to bring a can of hairspray is a mystery. But if this were the case, then that spray might be just the thing that saves the night.
Before you even think of attempting this hack, you should make sure that there is no risk of the fire spreading to the rest of the camp. Once all the precautions are put into place, aim the spray at the fire pit and turn on the lighter. Just kidding, please do not attempt this. Hairspray is highly flammable and setting it on fire can cause serious burns.
