**THE STUDY OF SPONGE ABSORBENCY**
Milen P 2012 - 2013

**ABSTRACT**
The purpose of this study was to see which brand of sponge could absorb the most water. There are many other similar experiments conducted such as putting gummy bears in water for different times to see how much water the gummy bears absorbed. Each brand of sponge was dipped into 800ml of water for 10 sec and then had 2 sec to drip. Each sponge was placed in water 3 times and then an average was calculated. The Domestix brand of sponge absorbed the most water while Scotch Bright and Ocelo didn’t absorb as much water. The Scotch Bright and Ocelo brand of sponge didn’t absorb as much because those brands had a scrubber which blocked water from entering through one side of the sponge. However, the Domestix brand of sponge did not have a scrubber so the sponge could absorb water from all sides.

**EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS**
A improvement that could be made to the experiment testing the absorbency of sponges after being heated in a microwave for different times could be to heat the sponges for longer times. If the sponges were heated for a longer time the temperatures would be higher. Therefore, the experiment would have more varied results. A future experiment that could be test could be testing the weight of the sponge after soaking it in water for different times. The sponge would be dipped into a beaker containing 800 ml of water for the required time. After, the sponge will be removed the beaker and it will have 2 sec to drain water before the weight of the sponge will be measured.
