   Since the water did not freeze in the centrifuge, we were obviously unable to test our original hypothesis.  However, we did come up with four theories for why the water did not freeze:

      1. The vibrations of the centrifuge gave the water too much kinetic energy and this prevented the formation of the H2 bonds necessary in ice.
      2. H2 bonds could not form because of the centrifugal force present.
      3. The temperature inside the centrifuge did not go below freezing either because of the insulating properties of the container of the centrifuge, or because the motor created enough heat to keep the temperature above the freezing point of water.
      4. Kinetic energy transfer from constant acceleration increased the internal heat of the water.

   We know that the condom was not the factor preventing the water from freezing because we put the same amount of water (10 cc) in a condom in the freezer and the water froze in about 20 minutes.  We also put the same amount of water in a condom in one of the metal test tubes and it also froze.  We came up with a few ideas that might further our future research.  The first would be a longer trial period for the tests.  We might try a 24-hour trial, instead of the maximum 3.5-hour trial time we tested; in high gravity water may just take a long time to freeze.  We were limited in the time for each trial by the equipment we used, since the centrifuge only ran in 30-minute increments and we did not want to overwhelm it by resetting the timer too many times.  Therefore, we would also use better equipment in the future, such as a centrifuge that could run for longer periods of time, and also that was more stable so as to eliminate any extra motion in the water.  We would also try a colder freezer, in case the freezing point of water is lower in high-gravity and our water did not reach this temperature.  All of these factors could have contributed to the outcome of our experiment.
