Using the Nerf Super Soaker Twister is a breeze. First, open the cap on the blaster and fill the tank with water. You can use a faucet or a bucket. The tank can hold 37 fluid ounces or 1094 milliliters of water. Once it's full, close the cap tightly. Then, start pumping the handle back and forth. This will make a cylinder in the tip of the barrel rotate, and it'll shoot out two twisting streams of water. Aim at your friends and have a great water fight! Remember, this blaster is recommended for ages 6 and up. After using it, empty any remaining water from the tank. Store it in a cool, dry place to keep it in good condition. Don't leave it under direct sunlight for a long time as it might damage the plastic parts. Also, if the blaster gets dirty, you can use a mild soap and water to clean it, but make sure it's completely dry before storing it.
