Time-keeping has never been this psychedelic or fun! Watch as multi-colored globules drift lazily through the transparent center, counting off the seconds. See the liquid separate into interesting shapes and patterns only to reform back together at the bottom. The timer can make timed board games more fun, or it can just be used as a cool desk decoration, or a classroom fascination. However you use it, the Floating Color Timer is sure to entertain and please.
