You can adjust the system such that one of them is moving down and one of them is moving.
You can also have them both float in the middle.
We have this kind of competition in Taiwan. Each one will play with 8 to 10 divers.
If the hole in the diver is different, the water leak out/in rate from/to the diver is also different.
Press the system slowly or quickly will have different effect on the divers.
Each diver can be controled, moving down or up by your hand. One diver can also rescue another diver.
They are many ways to play with it. I hope you can make one for yourself and enjoy the fun playing with it.
