This water–reducible acrylic–based paint sticks to most surfaces and glows in the dark after only a brief exposure to bright ambient light. We have a 2 oz bottle of yellow/green that will glow for up to 20 hours. This works great for Halloween costumes and hobby applications, and glows like crazy under blacklight. And without a single radionuclide! Amazing!

Never seemed fair to nail the "lazy" tag so permanently on the "Susans" but that probably has no "bearing" on the issue. Also called turntable bearings, they are the square, flat ball bearing devices YOU bolt between two flat objects to achieve rotation. Like that spinning center section of a Chinese restaurant table. We had these in surplus once and they were quite popular. To our chagrin, we discovered they could be bought commercially for the same price. So we did. The 4" version is rated for a 300lb. load, the 6" for 500lbs., and the 12" (round) for 1000lbs.

A couple of pulleys just ready to be combined into the block and tackle you need for tiny jobs, like trimming your bonsai trees or hauling your model boat out of the pond. Get blocks with (1) or (2) sheaves and rig up whatever you need. Each block has an aluminum frame about 3–1/2” long with “S” hooks on each end. The sheaves, or wheels are about 2” dia x 1/4” wide, with a “V” groove that looks perfect to handle 1/8” or smaller Venetian blind cord. These dudes are perfect for demonstrating mechanical advantage in the physics lab!! But not for heavy lifting.

A trio of the best science education kits we have seen dealing with electricity, magnetism, motors and generators. The 44 page instruction booklets are educational and complete; state problem, approach and explain what is happening for a series of projects of graded difficulty. The Motor/Generator kit includes several introductory experiments on magnetism as well as six complete motor generator projects. The Electromagnet kit provides experiments including the building of an electromagnet, a doorbell chime, a telegraph, a relay and an electric catapult. The Levitation Set experiments with magnetic fields, gravity, and equilibrium; plus everything you need to build a magnetic levitation train! All are complete except for batteries. Strongly recommended for their quality, the accuracy of their science and the interest they will sustain. Ages 10-18.

One of those sharpie East Coast outfits pulled a fast one on this poor naive Midwestern dealer. The result is we have a pile of exotic coated copper magnet wire. The coatings and colors vary widely, as does the gauge of the wire. With a couple of exceptions there isn't enough of any one kind among the hundreds in the pile to list separately. So we are offering an assortment and you get whatever we grab. Either way you will get a terrific value, particularly if you have an exotic application and get just what you need. Even if you are just making a garden variety coil or electromagnet you will still find the prices are very good. So go ahead, profit from our misfortune. We are glad to be of service. Sigh.

The wave of the future. Create your own ISP or long-distance phone company. The plastic fiber-optic cables are clear, 1/32" dia single strand. Unjacketed is IFC-U1000, 1000nM. Jacketed cables are encased by black plastic, 1/16" OD, IFC-E1000, 1000nM. What do modelers do with it? A recent magazine on model railroading showed how to build a lighted marquee using fiber optics. Pretty neat!! The big boys get $1.60 to $1.90/per foot for this stuff!! All fiber optics sold in 10-ft lengths. Extremely neat!!
