StratoLauncher IV Water Rocket - Launches Bottles 350 Feet!
If you thought the eruption caused by dropping Mentos into a bottle of Diet Coke is exciting, then prepare to be blown away with this cool new StratoLauncher IV - Water Bottle Rocket. This fun miniature launchpad is designed to launch a 2 liter soda bottle over 350 feet into the air using tap water and compressed air - no rocket fuel required. To use, just add a cup of tap water fuel into a 2 liter soda bottle that you supply, add the stabilizer fins, place it on the launchpad, pressurize the bottle with a bicycle pump (safety valve prevents catastrophic bottle explosions), and then step back ten feet for safety and simply squeeze the lever on the controller to launch. Perfect for backyard fun, science projects, or just practice for future rocket scientists. Check out the video below to see it in action.
