A size comparison of golf balls, from standard golf balls to oversized.
Remember when standard golf balls including a British R&A golf ball and an American USGA golf ball had 2 different sizes?
The R&A ball was formerly 2.06 cm in radius and 45.93 g in mass, the USGA ball is 2.13 cm in radius with equal mass, making it slightly denser.
Eventually there was an agreement that both golf balls would be the same size, but this simulation shows otherwise.
The 45.72 cm radius is from a giant golf ball that Irish residents display as representing transformation into leprechauns.

Yet despite their high mass, they're relatively lightweight for their size, due to the fact that they're mostly hollow, so that if you put them into an ocean, they would float (whereas standard regulation golf balls would sink).
