Watch as the coloured drops zig and zag throughout their respective chambers in this desktop toy. Turn it back over and watch the liquid drop back down to the bottom. You'll be able to add some colour and excitement to your work area with this cool liquid motion drop timer. It is based on the same insolubility principles as an oil and vinegar dressing, so it can also be used as a scientific demonstration as well. The shell is made of a sturdy, clear acrylic that features a divider down the middle which separates the two colours.
