My eighth grade classes launched their water rockets last month. I took video of the students and their rockets and now have it posted to our school’s website. I made an iMovie from all the video clips. I originally had it as a twenty minute video, but I edited it down to about four minutes so it didn’t take too long to upload and play. This is my first attempt at shooting the video, editing the clips and posting to the school’s server. Check it out.

The rockets are made with two, 2-liter bottles. The top bottle is where the astronaut egg is located. The goal is to keep the astronaut safe and secure by designing an enclosure around the egg so it doesn’t crack.  All types of materials are used and must be accounted for in the final cost.

The bottom bottle is the engine. We fill the bottle about half full with water and I pump it up with about 60-70 pounds of pressure. I have a specially designed rocket launcher that keeps the rocket set until I pull the pin. The students work in groups of two and this project takes about a week to complete.
