Great for STEM teaching. Turn bubbling concoctions in to fuel to power a rocket that will soar into the air. Learn to make exploding bags and geysers. Use the included hook and loop straps to attach your there rocket wings to the bottle. Water Rocket - Add some fuel and pressure and the result is fun launch after launch. Geyser Tube - Open the roll of Mentos and remove 5 mints. Load the 5 MENTOS into the Geyser Tube. When your ready pull the pin in so the mints fall into the soda and stand back. You won't be able to do this experiment just once. CO2 Sandwich - Don't plan on packing your lunch with this explosive science sandwich. In this experiment you will mix vinegar and baking soda to make bubbles of carbon dioxide gas. What makes this really fun is that the bubbles will be trapped in a zip-lock bag. With just the right formula, you'll be able to make the bag POP.
