Every fall we have a Water Rocket launch. You and your family can design a water rocket using a bottle of water or soda. We then have a launch party and fire rockets and measure for distance. Scouts can choose to build rockets alone or team up with friends if they choose. Below are instructions on how to build your rocket.
Big Smartwater or 2 Liter Bottle

Tips - Hot Glue & Cardboard/Cardstock/Plastic is your friend for fins, cones, etc... But NO HOLES in bottle from glue gun - we need air to compress..
