Watch as one set of drops fall down from one bulb and up to the other in this 3 tall desktop toy. Once all the drops gone end over end just flip the cylinder over and start again. Add some color and excitement to your work area with this cool liquid motion. Using the same insoluble based principles as an oil and vinegar dressing it can be used as a scientific demonstration as well. Drops fall for approximately 90 seconds. Show more
