It is highly unlikely that you would be able to get golf balls for free. The only way you could do so is a promotion with a golf magazine or something. If you go play golf and find some golf balls you can keep them, however, you can't just go to a golf course and look for golf balls, this is illegal. The issue seems to be perhaps you think golf balls are too expensive, there are a couple of options you could buy budget golf balls or buy lake balls, these are used golf balls which are a lot cheaper.
The best ball for putting is one that is perfectly balanced, so it'll stay on line. But golf balls aren't really advertised in this way. And no golf ball is marketed as a ball for putting. Most golf balls are very good for putting, but the premium ball ranges will be softer.
No golf balls do not melt in water that way.
I am just going without research on this, but you could test different types of golf balls and see the results and what golf balls work for different people. You research the way the golf ball compresses as well. hope this helps!
The numbers are used to identify the golf balls while in play. That way players don't confuse the balls. At the beginning of the round, players should compare balls so that everyone knows what the others are playing with.
Some golf balls are designed to float. Some golf courses offer practice ranges where golfers hit from the practice tee (ith floating balls) into a lake or pond. Instead of a golf cart retrieving the range balls off the ground, either a boat collects the floating balls or the artificial pond is design in such a way that the current moves the balls to a collection area.
The way a golf ball bounces definitely affects the distance that it will travel. There are different weights and types of golf balls for this reason.
The best way to clean your Bassett Hound's ears is to use an ear cleaning solution and cotton balls. You'll want to clean the outer ear and the inner ear but make sure you don't push the cotton ball too far in.
The best way to clean a dartboard is with a cloth and shining polish.
The best way to clean a suit is to have it professionally dry-cleaned.
I find that the best way to choose a new golf ball is to try out some different ones and know what you can do with each one. Then before you play in a competition, know what you will have to do and use the correct ball for the bob :)
