I grew up playing paintball. They're just liquid balls in a thin plastic. With a jacket on they won't bother you too much. At 50 ft the rental guns will start to stop breaking, especially on soft clothing. At 100ft the best guns you can buy will start to stop breaking even on bare skin. I have a hard time imagining them being effective outside of a very small set of circumstances.
