How to input objects into the bottom of a water tank.

Click For Summary
The discussion focuses on designing a system to dispense buoyant balls into a water tank for a children's game. The proposed mechanism involves a multi-atmosphere container that alternates between air and water to facilitate the balls' movement. Concerns are raised about the complexity of the design, with suggestions for simpler alternatives, such as using a tube and a stick to push the balls into the tank. Safety considerations are emphasized, particularly regarding the tank's size and accessibility for young children. Overall, the conversation explores various ideas to achieve an effective and safe dispensing system while considering ease of use and automation.

I am; unfortunately Dave is no longer a member of the PF community.

Well, the post #20 design, with a return mechanism, would be one way to spoof a buoyancy pmm.
These things can be quite neat as art - a water-feature?

Dave's was a simpler idea which also addressed, indirectly, the main begged question: why not just push the balls in? Why gravity feed? (The grav feed is a common requirement for the buoyancy pmm designs.) Your's has the needed distractions.
