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.

Flat plastic Fresnel lens. This flexible magnifier is 7-1/4" x 10-1/4" and only about a millimeter thick. It is great when you need to scan a list or to look for something in a directory. You can see most of the page without moving the magnifier. Only about 1.5 power, but that can make a huge visual difference. The quality is not high, but neither is the price.

8665 MAGNIFYING SHEET |
Need to hold something to a round steel pole? Want to make a magnetic bulletin board? Or to cut some letters for a temporary sign on the side of your car? Relax, the answer is at hand. You need some flexible 12 x 12 rubberized magnetic sheets. The magnetic particles are embedded in a rubber-like material that is easily cut with a pair of scissors. Strong enough to cling firmly to a smooth metal surface or to hold light objects. Sheets are just over 1/32" thick and are self adhesive.

4303 SHEET MAG, 12"X12" ADH |
“Mag” could mean “magic” or it could mean “magnetic.” Some people tell us that the terms are interchangeable in this case. The fleshcolored donut–shaped ankle bandage sticks a circle of (15) 3/8” dia 400–gauss button magnets around your ankle bone. Our each is a set of (2), so if you’re not into magnetotherapy, you still get a slew of cool little magnets.

The ultimate in refrigerator-door decorating: a 25-foot x 3/4" wide roll of dark brown magnetic tape in a handy dispenser with a tear-off bar. Rip off a strip of tape, stick the sticky side to a photo, art project, or note and the magnetic side will hold it on a refrigerator door, file cabinet, or any other steel surface. Light duty, like all fridge magnets, so stick to notes and pix and other fluff.

10584 3-LB CERAMIC MAGNET |
Rare earth magnets are usually killers for their size, and these thick nickel neodymium discs are no exception. The price, on the other hand, for (3) 7/16" dia x 1/4" 5-lb lift or (2) 9/16” dia x 3/16” 8-lb lift magnets each stored on a 2" dia steel disc, is a rare exception.

93515 MAGNET & PULL |
Like a 300-lb Labrador for the shop. Our ceramic lift magnet is mounted in a metal housing with swivel that will attach to a standard threaded broom handle or painter's pole. Will lift approx 65 pounds, enough to retrieve microwave ovens from storm sewers or pull a small outboard motor from the bottom of a lake. Maybe.
