Red, Green and Blue Gloop Timers. Approx 40 Seconds. Great Destop Stress Toys. Turn this little 40-second hourglass over three times for two-minute eggs, give or take five seconds a turn, because this is really a desk accessory and not a timer calibrated at Greenwich. And it drips gloppy glycerin because it's much more fun to watch than sand. Measures a chunky 2-3/4" tall x 1-3/4" dia. You get a set of (3), one each with blue, red and green glop.
