My physics' students had a day to design, build and name a rocket. They could use two 2-liter bottles, cardboard, tape, string, plastic and styrofoam for construction.

There a lot of young rocket engineers checking the internet for cone specifications, ideas for parachutes and stabilizer designs.

After putting on the last alterations, each team launched their rockets. To level the playing field for all, each rocket had 500 mL of water and 75 pounds of air pressure.

Here are the rusults.

First Place: 8.00 seconds

After very aerodynamically smooth rocket went almost straight up and straight down, I add a new category - highest altitude.

 Slow motion

Highest Altitude 82.1 meters

Time: 6:34 seconds

One rocket's parachute deployed - the first in my bottle rocket launching career.

Here is a pre-launch interview:
