When doing outdoor bubbles, heavy in secret ingredients, sometimes when they pop over head there results a white gooey streak that plops down on some unsuspecting person's shoulder. When someone remarked the white spray looked like a mini fireworks display, I just decided to give in and make lemonade (so to speak). I now call that shooting white mass "special effects", and tell people how lucky they are to be privy to such a secret solution imbued with such magical properties. They usually agree... Unless it was their shoulder. In this clip because it's in slow-motion, you really get the chance to see the special effects in action.
