Bottle Rocket Launcher

Bottle

     These launchers use air pressure and water to propel a bottle 50 to 100 feet into the air. The launcher holds the bottle by "friction". Air is pumped into the bottle. When the force of the air pressure inside the bottle overcomes the force of friction holding the bottle down, the bottle shoots up into the sky.

     Another version made with heavier materials for more safety and durablity.  Some slight modifications are also made.

Bottle Launcher with Egg Drop Basket

     Bottle launchers being used at Day Camp.  Note the wire baskets taped onto the bottles, these are used to hold the containers holding the eggs while launching.
