Such a funky timer is essential for anyone who relishes quirky desktop bobbles that have a practical function. This tube contains a special neon coloured goop which slowly oozes from one chamber to the other. As air bubbles rise through the sappy liquid, the tube resembles a retro lava lamp and the air pressure forces the aqueous liquid to flow downward. Turn it over after about 10 minutes to watch the bright, viscous fluid drizzle slowly to the bottom again. Each tube comes with either bright red or blue coloured goo. Great for those who love unusual yet practical gifts!
