What is that?

I've seen my fair share of hail... but never for more than like a minute. Not the case today. We had what I call a good hail storm at our house this afternoon. Some of it was moth ball sized hail & it went on for a good solid 8 minutes (maybe even longer). These little pellets bounced all around our yard and looked like ping pong balls. Our trampoline was covered and the flower pots were full of the little white pellets.
