Estes Hydrogen Rocket Set 1876

This is rocket science! This fascinating model rocket generates its own hydrogen fuel from ordinary tap water. Your budding scientist will love making fuel that is clean burning, environmentally safe, energy efficient and abundant enough for unlimited launches. "Green" hydrogen fuel technology starts with plain water and included crystals of citric acid ; you mix these two and pour them into the Fuel Generator. A red LED on the launch base indicates power is on; a yellow LED indicates an electric current is separating the water's hydrogen molecules, which rise into the reaction chamber. When the green LED glows, you're ready to grab the Launch Cable and press the Ignition Button and "BOOM" ? the hydrogen gas ignites, expands and propels your rocket high as 10 stories into the air! The rocket is 11" long; the launch base is 20" x 10". Runs on 6 D batteries . 90-day warranty. Adult supervision recommended for children 10 and younger. minimize
