The ETA hand2mind (23147) Double Bottle-Rocket Launcher provides students in grade 5-9 (age 10-15) hands-on experience studying force and aerodynamics by turning a plastic soda bottle into a water-propelled rocket. Students create custom designs and build their own rockets, testing variables such as water level, air pressure, and aerodynamic design choices such as fin placement. For competitive or comparative events, students can launch two rockets simultaneously. A paper astrolabe is included for measuring rocket altitude. This launcher is designed for use on soft turf where the launcher can be secured (requires Bottle Rocket Launch Pad (55502, sold separately) when launching from a hard surface such as parking lot blacktop). This kit includes rocket launcher, tubing, hardware, paper astrolabe for measuring rocket altitude, and instructions. Requires plastic soda bottle, and bike pump to launch rocket (sold separately).Science education products incorporate applied math and science principles into classroom projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.ETA hand2mind develops educational and supplemental materials for teaching math, science, reading/language arts for pre-kindergarten through grade 12 students. The company, founded in 1968, is headquartered in Vernon Hills, IL.What's in the Box?Double bottle-rocket launcher for launching two rockets simultaneouslyPaper astrolabeTubing Hardware Instructions
