Hey, don't put hard stuff in with your paint. Instead, replace gumballs at your office or Halloween candy with marballizer or Hellfire. It's by comparison harmless and can be really good for a laugh every now and then from that co-worker that really deserves it. There's a shade of BigBall that looks like Milk Duds or Whoppers (chocolate malted milk balls for those of you overseas that may not have those particular brands) that never fails.
