Re: Golf Ball Task
There are indeed competition standards for golf balls. If you purchase standard, commercially-available golf balls you should be fine.Unome wrote: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.chessbucket wrote:What defines golfball?

Re: Golf Ball Task
I think that a buoy would be required. Moreover, I think that you could have a golf ball waterslide. The golf ball and a bit of water would flow over, and the water would be recycled into a lower container.

Re: Golf Ball Task
A new clarification has been posted regarding the golf ball:
Mission Possible - 10/5/18 (Division C) 4.b.iv. should read, edits in bold: Add water to a container to raise a standard, unmodified golf ball located in the same container at least 5 cm so that the golf ball rolls out of the top of the container and initiates the next action.

Re: Golf Ball Task
One possible way to use the least water would be to get a small section of 2" PVC pipe. Cut the exit end on something like a 45 degree bevel.
A float could be a piece of wood also cut on a bevel to force the golf ball to go where you want it to go. Since I have it, I would use a 1 3/4" hole saw to cut it our of a 2 x 4. Consider using poly urethane or a spray lacquer on it to waterproof it. Alternative is to microwave it for 1 min on high to dry it out. Caution, the wood will swell slightly from the water. Best to have 2 dry ones. By making it a little bit taller you could control the time by controlling the starting amount of water in the pipe.
Options for the wood could be a proper size plastic fish bobber or a large cork.

I like this idea. Its simple and seems hard to mess up at first glance at leastretired1 wrote:One possible way to use the least water would be to get a small section of 2" PVC pipe. Cut the exit end on something like a 45 degree bevel.

Re: Golf Ball Task
I have a simple solution but it might be problematic depending on what a container is.
Does the container for the golf ball have to be able to hold the ball through it's entire length. For example, could you have a narrower section connected to a wider section which holds the golf ball, with the entire apparatus being considered a container?
