We settled on the pulser pump idea because of its originality, reliability, simplicity, and adaptability. Our prototype looks a bit like an octopus. It consists of an orange juice container with three holes, and a thin tube extending from each hole. Cassie and Ashwin were nearly defeated by the difficulty of making holes, but they are scientists, and scientists never give up. So on they went, armed with Exacto-knives and pure testosterone (in Ashwin's case) and adrenaline. They holed the orange juice container. Unfortunately, we are skeptical about its viability. We will see how it works at the trial.
When we tried it out on the lawn, the water flow was inferior, and the container leaked. We need to tighten the container and have something bigger than the tubes. We absolutely must increase the waterflow and thus the airflow.
