Product Description

The ETA hand2mind (23146) Single 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. 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).

The Science Source Single Bottle-Rocket Launcher Review

Good things
-Holds up well to light and moderate use
-Seals well to 2 liter bottles (I have yet to try other sizes)
-Stakes remain in ground for several launches if placed properly
-Thorough instructions
-Only requires a pump, water and soda bottle in order to use
-No safety automatic safety release (this could also be a drawback, but for my purposes I liked it)

Things I did not like
-Difficult to stake (requires considerable effort or technique)
-Sharp edges require adult supervision when handling
-Friction fit plastic tool attached to release string. Becomes dirty easily and secures only loosely

If one can get this into the ground straight, it works well repeatedly. If one doesn't have experience with launchers like this, it can be hard to set up, but I like the design and exploratory value of this launcher. I have only owned mine a few months, but it shows little evidence of deterioration. I will update this review if anything goes wrong in the near future, but I don't expect to need to.
