Using these Nerf Super Soaker water blasters is easy. First, find a water source like a bucket or a pool. Dunk the tanks of the water blasters into the water, and watch as they quickly fill up. Once filled, you're ready to play. Hold the blaster firmly and pump the handle to shoot water at your friends. Remember to play in an open outdoor area to avoid getting the indoor areas wet. When you're done playing, empty the remaining water from the tanks. Store the blasters in a dry place to prevent rusting. If the blaster gets dirty, you can wash it with mild soap and water, but make sure it's completely dry before storing it.
