Hey; HotWheels aren't made of metal? Well not magnetic attracted metal. Trying to come up with a new display, over the regular rack, plastic holder, peg board or........ I was thinking of making my own drag race display? Anyone ever built something like that? Was thinking using my yeller n white GSX's for that. A classic grudge race that is all based on color, with all other things being equal. I had a brain fart that maybe a magnet could be used to put them in a slight wheels up or full on just launched stance. Use a strong rare earth and find a way to rotate its poles for push or pull. Instead of using wires or glue. The cars could be moved off and be unmolested. Or use other cars. Thats not going to happen hugh? Just blows my whole idea.
Probably for its low melting/flow point. Around 500F from my personal experience messing up some potmetal parts [For powder doing a heat clean cycle.]
