Build rockets from ordinary plastic soda bottles that can soar to heights in excess of 150 feet! All you need is water! This solid aluminum bottle rocket launcher allows you to pressurize any plastic soda bottle (from 500 ml to 2 liters) with an ordinary bicycle tire pump. A quick tug on the release cord and your rocket climbs skyward. Included with the launcher is an instruction sheet and an altimeter you can assemble to measure the height of each flight. Bottle Rocket Launch Pad (shown) not included.
