3.   Results
3.1    Sampling sites
We sampled the results in the Science Laboratory and under the staircase. The experiment was originally started in the Science Laboratory, under the eye of the lab manager. However, due to faults in the silicone sealant, the Liquid Glue gave way under constant pressure, and flooded the laboratory. Therefore, we shifted our experiment to a safer location.

3.5    Special observations


We observed that the results of the waves were not consistent. In addition to that, we also observed that there was a very large backwash occurring to the artificial beach, which swept the small pebbles out into the back of the tank. We also observed that the sand eroded away the silicon and made the tank leak.
