The bubble glass is an awesome desk-topper and a question-generating eductional tool. When the cylinder is flipped, the liquid flows to the bottom leaving bubbles in the top.

Who knew that by just replacing the sand in an hourglass with soapy liquid you could defy the laws of space, time, and physics and make it appear to flow in reverse? But that's exactly what happens with this fun timer. Watch the liquid flow to the bottom leaving the top filled with bubbles.  A great gift for children (or children at heart!)
