Recognize this digital atomic clock? You must be hanging around hospitals and other government institutions up in Canada, because this came from their actual supplier. Accurate to a fault and visible across a very large room, this giant digital clock refreshes and resets the exact time each night and is 16-1/2" wide x 10-1/2" tall x just 1-3/4" thick, with a clean, brushed-aluminum-look plastic frame. Displays time (digital LCD h/m/s, with h/m being 4" tall), time zone (select any of 6 North American zones), indoor temperature, day and date. It has 12- or 24-hour settings, choice of C or F temps, and mounts on a wall or sits on a built-in stand. Runs on (3) "C" batteries that come with it that last over an astonishing 1-1/2 years! Sorry as of now the clock does not have time zones for Alaska and Hawaii. Check out this youtube video to see the clock in action.
Budding lapidarians will lap up this rock polishing kit which is so complete it even contains some rocks.

In addition to the tumbler, the kit includes an assortment of jewelry findings, a #300 4-Step Grit Pack and a detailed manual giving you easy to follow instructions.

The #300 4-Step Grit Pack is also available separately, for when your grit has run low, and includes 4oz. coarse, 4oz fine, 2oz. prepolish and 2oz polish grits.

That's what you get with this tesla coil!! Brand new, commercial item, great for classroom demonstrations and experiments. The 50,000 volt capacity generator radiates high frequency energy through space... enough to light fluorescent tubes two feet away. It uses 115 VAC (60 Hz) with an electro-magnetically operated interrupter buzzer, high voltage capacitors, inductive coil transformer, and a monopolar high frequency transformer generator to do the trick. 11" high, with a 6" sq. x 2" high protective housing for the generator. Includes accessories and instruction booklet with 19 experiments. Pretty amazing. But please, this is not a toy and should be used only under adult supervision.
This skeleton is actually used in medical
and other schools for teaching. The bones are plastic, but other than
that it's as realistic and anatomically correct as they come. The
ready-to-use skeleton is mounted with a 360° swivel at the pelvis from a
heavy-duty metal rod on a stand base with castors. It has a skull with a
removable section, hinged jaw and (2) removable teeth; plastic zippered
dust cover; and stainless steel wire, brackets and wing nut assembly
for long life. It's articulated at all joints except the spine, so you
can demonstrate flexion/extension, or merely pose it in a debonair
posture. Size: 5' 6" tall. Weight: 23 lbs.
