Flinker DIY
Scuba divers exploring the ocean floor know about the importance of “flinking”. They want to be suspended in the ocean water without sinking down onto the coral and damaging bottom-dwelling sea life. The trick is not to float to the top or sink to the bottom, but to “flink”! (In Physics, we call this neutral buoyancy.) Can you experiment with the forces of gravity and buoyancy to create a diver who remains suspended in the middle of the water container?
