The POOF-Slinky 0SA203 Scientific Explorer Rocket Car will have children both young and old mixing baking soda and vinegar to create a fuel that will launch their very own Rocket Car over 200-feet, while learning lots about rocket science. As you watch a rocket blast off, you might ask yourself "What makes it go"? The secret to rocket power can be found in the work of Sir Isaac Newton"s laws of motion where every action produces an equal and opposite reaction. The Rocket Car is a powerful, high performance racer that"s easy to assemble and powered by carbon dioxide gas that forms from the chemical reaction between baking soda and vinegar. The high pressure fueling module is the secret to controlling gas pressure inside the Rocket Car, making it so you can adjust the reaction"s power to the right level for young racers or advanced land speed challengers. As you learn more, experiment with different proportions to create your own secret rocket fuel mixture. Your child will see chemistry and physics in a new light, while exploring chemical reactions, matter, energy, aerodynamics, and more. Experiments are recommended on large asphalt or concrete surfaces or fields where the dirt and grass are smooth. This kit includes a paper stock die cut axle support, (3) plastic wheels, (2) aluminum rods, rubber tubing, piece red plastic film, pieces silver duralar, fueling module, (2) plastic bottles, piece balsa wood, nose cone, 10-inch weather stripping, precut clear tubing, template and 10-page instruction booklet. Rocket Car is part of the exceptional series of home science kits based on the nationally recognized Great Explorations in Math and Science (GEMS) program pioneered at UC Berkley"s Lawrence Hall of Science. Scientific Explorer is the industry leader in fun, educational and activity-based science kits loved by both parents and children. The POOF-Slinky 0SA203 Scientific Explorer Rocket Car Science Kit is recommended for children 9-years of age and older.
