Kids will love this chemistry kit & physics toy by Scientific Explorer™! The Meteor Rocket is a science experience kids will never forget. Go for a new altitude record by varying the proportions of baking soda and vinegar, try balsamic vinegar to see if it gives an extra “kick” to the fuel, change the fuselage length to test flight characteristics. Chemistry and physics will never be the same! The baking soda and vinegar formula starts a chemical reaction inside the patented fueling module, creating enormous power that blasts the Meteor over 100 feet into the sky! Rocket is 20 inches tall. Learning toys are the perfect gift for kids, children will love that they are able to launch an actual rocket, and parents will be happy to see their children doing an at home science experiment! Ages 9+.
