We had a chance to fly an experiment several times this weekend that we have wanted to do for quite a while. The purpose of the experiment was to demonstrate what forces act on internal components of a water rocket in flight. Gravity based parachute deployment systems appear to work on the ground, but are unreliable in flight.
The experiment shows what happens to a handfull of loose M&Ms inside the rocket during take-off and susequent zero-G (freefall) conditions. The M&Ms were inspired by Mike Melvill's handfull of M&Ms inside of SpaceShipOne.
The update includes lots of photos,videos and an explanation of the experiment.

The update also includes our first altimeter flights and some interesting results about foam.
