Physical Compression Test
In order to conduct the physical test, samples of 90 ppi foam of circular cross sectional area (1" diameter and 1" depth) were used. First, a trial using four pieces of foam samples was conducted. The four pieces of foam were placed on a level table and even spaced underneath a plastic beaker such that all four pieces were entirely covered. Water was gradually added to the beaker until slight compression was noticeable. This minimum water volume was recorded. Water was then continuously added to the beaker again until full compression occurred. This maximum water volume was also recorded.
Note: It was important to record the maximum water volume as the point where the foam first reaches 100-percent compression.
Discuss methods used to complete the experiment here (three trials using one piece of foam, one trial using two pieces, and one trial using four pieces).
