Our club had their own booth set up at the annual Geeks' Night Out in Downtown Tempe. At our booth we mentioned the activities of our club and showed event goers the plants we grew.
We also tried a new experiment at our booth- purifying tainted water. The unclean water is first poured into the top layer of the mechanism and is then left to settle out the sediments from the water.
After approximately 30 minutes, the valve is opened to let the water from the top tank flow into the middle tank. In the second tank, little microorganism clean the impure substances from the water. Gradually, the water will become clean in the third tank where some substances are added to ensure the purity of the water.
