The classic swinging balls, to amuse you on slow days in the office or physics lab, and to demonstrate Newton's Third Law. Drop one of the five hanging balls, one flies out from the other end; drop two and two fly out; drop three and it's amazing. The balls are set in a 7" x 9" x 9" high wooden frame. Isaac didn't invent these mesmerizing toys, by the way. That took Simon Prebble (whom some of you may remember as the evil Martin Chedwyn on "As the World Turns") who had an energy transference inspiration in 1967. (Where else can one learn these things?)

Power Wool(tm) pads from NicSand were made to fit 5" disc sanders and 8-hole vacuum sanders, but we like them as steel wool pads that happen to be self-adhesive. There are (3) 5" pads in each pack. Each pad has (8) holes in it. The cleaning and stripping pads for metal and painted/varnished/urethaned surfaces are an extra-fine "0" grade. For smoothing and deglossing between coats, they are an ultra-fine "00" grade. For finishing and polishing the coated finishes, a micro-fine "0000" grade. Nice quality. Made in the U.S.A.

Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgandy, green and purple, but there may be other colors yet to be seen! A great discovery device whether for biology or other pursuits. Not of professional quality, but not just a toy.

A fine concept and pretty successful execution. Weighted bases hold fully adjustable clips and lenses for delicate hands–free work. The Helping Hand w/solder has a 2” high base connected to (2) alligator clips via (3) universal joints and a 4–1/2" sliding beam, and to a 2–1/2" dia roughly 3X magnifier via another universal joint on the sliding beam. It also adds a holder for your soldering iron, plus a hole and thumbscrew in the base to firmly position it. The larger Work Stand has a 3–1/2” x 4–3/4” stand with a 2–3/4” square x 3/8” deep reservoir to hold small parts, an L–shaped sliding beam with (2) alligator clips, and another L-shaped beam with a 3–1/2” lens, about 4X magnification. Joints adjust every which way. The set screws can all be hand–tightened, but we suggest a small pliers to secure the hefty 4X lens. Think of the clips as extra hands to hold wires, components, beads, what-have-you while you perform some operation on them with your own two hands.

Our aluminum canisters with clear glass pull–off lids are cool. When a set of a dozen contains lavender, red and 10 other colors, it’s cool to the max. The smallest canisters are aluminum–colored, a set of (20) 1–1/4” dia x 3/4” deep in a 6–1/2” x 5–1/4” x 7/8” lightweight aluminum box with a hinged lid. When the box is shut, a layer of foam padding inside the lid presses down on the canisters, keeping them securely closed. An ideal carrying case for paints, many different screws, or other sets of small items or quantities that must remain separate. If you need slightly larger canisters, and a cardboard box will work instead of a carrying case, try our colorful display, anodized tins in great colors come in a set of (12) 2” dia x 7/8” deep. Prices are per set.

Flexible, strong and wiry. No, not one of those guys who climbs rock walls for fun. We're talking about our roll of 24-gauge (.023") solid wire that we believe is stainless-steel. Perfect for the workshop, and a nice weight for hobbies from bead-stringing to wreath-making. We'll clip off 20 ft to share with you.

Absolutely incredible device! The Mirage®, a precision optical instrument, creates three-dimensional images of objects of your choice where there is nothing. Drop pennies, keys or similar small objects (your sister won't fit) into the 2-3/8" dia opening of this 9" dia x 3" high flying-saucer-shaped disc, and a perfect image of the object will appear floating above it. The image is so real friends will try to grasp it, but their fingers will close on thin air! Use it as a high-tech centerpiece with a flower as the object! A booklet (included) explains the magic. New coating provides protection for the mirror surfaces. Highly recommended. Made in the USA.

You'll want it. Everyone who sees it wants it. The 8" x approx 2" dia tool (it's slightly elliptical to fit comfortably in your hand) comes in a fitted plastic carrying case. It has a solid, quality feel and weighs in somewhere between a rotary and a full-sized power tool for true versatility. It comes with (4) interchangeable attachments about 4-1/2" long. There is a grinder that also cuts and polishes, a triangular-head sander, a jigsaw, and a chisel/gouging head, plus more than (40) tips, blades, pads, etc. for the attachments. It has a thumb-wheel to vary the speed from 8000 to 23000 rpm, an on/off switch, and a power cord over 6 ft long. Think beefy rotary tool for use on wood, metal, plastics or stone. Yup, you'll want it.
