Dandiest Donut in the Domain

Donut magnet you can take to town!! 74mm dia x 14mm thick with a 30mm hole. Very strong and well pedigreed - in fact, its kin are activating pacemakers. They are of a high permeability ferrite material with a lovely light blue or white epoxy coating. Okay, we have them because there is the odd bubble or scratch in the coating which ruled them out of the medical ball, but they're fine company nonetheless. Good display bases, paper clip traps, and super for classroom demos.

Clever Idea #763

This idea is for the birds. Literally. A green/black plastic perch, dish, and dispenser that you can screw onto an inverted plastic pop bottle to convert it into a bird feeder. Obviously, the bottle should have been emptied of pop and filled with seed. One of those "100 things to do with old coat hangers" ideas that really works!! Complete with instructions and bail to hang the completed feeder. Please note: this feeder will not attach properly to the new Coca-Cola low-profile bottles.

Hobby Tools

We like these small pliers and cutters - they're a higher quality than most of the Chinese import tools we're offered. They are drop-forged, high-carbon steel with double-leaf springs, lap joints and rubberized foam handles. There is a trim 6" needle nose, and a 4-1/2" mini-round diagonal cutter. For precision work and hobbies, and especially nice for anyone with small hands.
