Any tips on how I can make a trail of sparks(the more the better) as a chassis runs down the track? I'm thinking wheel standing cars trailing sparks! Any tips, suggestions or even body style ideas would be great.
Sparkin hotrods. I had the set. The flints wore as suspected, grinding on sandpaper set into the guardrails. Goofy solid right rear tire with a tiny hole in the middle held the flint. neat idea, cheap to do, maintain. Goof-proof unless you installed the sandpaper backward. Even the goofy rear tire had its own special sized hub so it could only go on one (proper) side. I still have the cars and package of extra flints. lolThe flint deal is a page straight outta Tyco-ville, cept they wiped them on the guard rail...I fergit what the set was called
