Research on suitability of existing pool balls for enhanced players

Conventional pool balls are not suitable for players that can achieve ball speeds over 400 mph.  Likewise ordinary materials like wood, stone or concrete  could be turned into deadly shrapnel with super strength. Individuals with extreme energy blast or telekinetic powers could affect larger areas.

Supervillains could easily create mayhem and mass destruction with effortless use of incredible superpowers.  Humanity's  only hope is to have a protective force of superheroes to deter detect and repel any unfriendly supervillains.

We certainly saw Kara perform her feat on SuperGirl at the pool table on her date, where she cleared all the balls off the table in one shot on her break. Nice Strike Melissa! "Oops! Beginner's Luck!" I think she said.
