Using the FOM Mania Fomilator 2 Pack is super easy. First, pour the foam concentrate into the Fomilator reservoirs, then fill them up with water. Once that's done, you're ready to load, aim, and start your foam battle. You can shoot thick, fluffy foam up to 15 feet! When using the product, keep it away from your eyes to avoid irritation. Also, make sure to use it in an open outdoor area. For maintenance, after each use, empty the remaining water and foam concentrate from the reservoirs. Wipe the blasters clean with a dry cloth and store them in a cool, dry place. This will help keep your Fomilator in good condition for many more foam - filled adventures.
