Review on TMI Submersible Aquarium Fountain Hydroponics by Cynthia Guarente

My student's independent math project was to build a well. I found this when I was looking for a pump. They looked forward to it when it arrived (high schoolers, btw) and it worked. Next time they tried, although the pump didn't work. They had to disassemble it and rebuild a part to make it work again. In the end, they completed their project but regretted not having purchased another pump.
