Flying spit bubbles! — 3 weeks ago
OK So I’m waaaaay to old to have just learned this, or to be doing it at all. But I’ll give you some instructions. First off, you must be well hydrated. If you don’t have enough spit, it won’t work. Second, practice getting a spit bubble on the end of your tongue. Third, g-e-n-t-l-y blow the bubble off your tongue. It took me a few tries, and I’ve only just started, but I’ve been getting at least 2 a day since I figured it out.
