First get an empty eye solution bottle (that you can squirt), rubbing alcohol, and an empty dish. Then, put in two teaspoons of ground cayenne pepper into the empty dish. Then, put in about four teaspoons of rubbing alcohol (double the amount of cayenne pepper put in). Mix the solution thoroughly. Next, get out a spoon, and stir the mixture well for at least a minute. Then, take the whole top off of the empty eye solution bottle and fill it with your cayenne pepper and alcohol solution. Then put the lid back on the top securely, and shake if some cayenne pepper has clumped. Now you have a bottle of pepper spray.
