Well, if you had a crystal ball, you'd be able to see that there's a crystal ball in your future, and you'd know not to pass up this very, very nice glass gazing ball. It's 4-1/4" dia (and heavy) and comes with a footed dark-wood stand that spins smoothly. The stand is just over 3" dia. Together, the ball and stand are 6-1/4" tall. Comes in a presentation and storage box. The perfect accessory for your next fortune-telling gig.
Time Is Running Out...
Like the days of our lives, the sand in these large glass timers is running out. You pick the hour-glass in a double teardrop shape with blue sand, which takes approx an hour to empty (nothing was certain in the pre-digital age, my friend), and stands 11-1/4" tall x 4" dia; or the three-chamber half-hour glass that measures 9" tall x 3-3/16" top and bottom, with red sand. Keep one on your desk and no one can accuse you of being a clock-watcher, or use it anywhere you'd rather not hear a beep.
Use this little stainless beauty to teach teenagers and older students how heat engines work Then keep it on your desk, where you deserve to have it! This low-temperature-differential Stirling engine is beautifully machined. It works with hot water, ice water, a combination of hot water with ice cubes, or a hair dryer. It measures 5-3/4" tall with a 3-5/8" dia flywheel and a 3-1/2" dia x 7/8" tall base. The speed with hot water is approx 150 rpm. This is a real showpiece, the best we've ever seen at this price. Includes a 7-page instruction booklet.
Go beyond the standard desktop distractions with these extra cool devices and make your co-workers jealous in the process. This twofer will score you a radiometer and a self-sculpting sand duner. The radio meter is a 5” high evacuated clear glass bulb (on a base) with a four-bladed vane inside that spins at different speeds depending on how much light it detects. The sand duner is a 7” x 5” frame that holds various colors of sand inside and never stops moving--a constant creator of artistic, mesmerizing sand dunes. You’ll never be more relaxed or inspired at work.
