The Ooze Tube is a nifty little desktop item that acts like a liquid sandtimer. The thick liquid (probably dyed glycerin) just makes it through the hole separating the upper and lower chambers. As you watch, you can even see an air bubble form in the liquid as air tries to go from the lower to upper chamber. When the bubble makes its way through the hole it allows a lot more of the “ooze” to go through. This is an awesome way to relax!
