Danielle and Michael make self-propelled rockets out of juice bottles in an adventure playground, and learn how a chemical reaction which produces gas can be used to propel a rocket.
Danielle and Michael make explosive rockets fly with the children at an adventure playground. By putting fizzy headache/vitamin tablets into a bottle with a sports cap, they make incredible bottle missiles. As gas builds up inside the bottle, pressure increases until the lid pops. When this happens, the lid pushes against the ground, pushing the bottle upwards. The liquid firing out of the bottle pushes it further, just like the gases coming out of a real rocket.
You can do this free science activity at home with just some bottles and fizzy headache/vitamin tablets. Experiment with different types of tablets, different bottle shapes, and the temperature of the water.
