This experiment was conducted to find out how much do different brands of swimsuits assist a swimmer in reducing drag in water. This experiment was done by comparing materials from Speedo Fastskin, Aquapel Hydrasuit and a normal polyester swimsuit.
Procedure preview:
1.    For this experiment, the independent variable is the type of swimsuit used. The dependent variable is the time for the test object (container filled with sand) to reach the pool bottom.
