Golf Ball Task

[Unome]

See rule 4.b.iv

Obviously one would want to control the direction of the golf ball's movement carefully. Another challenge will be ensuring that the excess water doesn't cause problems.

How could you make the ball roll out of the top of the container? Presumably the ball would only be ~50% above the water, so the bottom of the ball would be kept below the lowest lip of the container, since the water would spill out of the container above that height. Does anyone see a way around this?

You could put the golf ball on a tall buoy so it raises above the container lip before the water does

Is placing the golf ball on a floating device allowed? That would make this task a lot easier.

4.b.iv says the golf ball must be "located in the same container" as the water - that appears to be the only restriction. Therefore a buoy would appear to be legal.

In fact, something like this seems to be the only obvious way (actually there are other ways that I've thought of since, but I'd rather keep them to myself) for this task, since golf balls do not float on water. (They have a density of 1.26 grams/cc, so I don't believe that salty water would work either.)

Salt water would also probably be illegal based on the faq for the water-addition task from last year

What I meant was salt being in the same container as the golf ball, and dissolving.

What defines golfball? Does it have to be of a certain shape, mass, volume, etc? Certain golf balls are smaller or wider, and certain ones weigh more/less depending on the company.

I believe there's a generally accepted standard on golf ball mass and size limits - something like 4 cm diameter and some mass range equivalent to around 1.2-1.3 g/mL.
