Query: A great idea, but...

I bought two of these kits at a closeout sale because they looked interesting. Inside each rod is a piece of electroluminescent wire that glows a pale blue, and no matter what color rod one uses, it is still a shade of blue. That's fine, because all EL wire has a bluish look. The problem with this kit is that the connector balls are very cheaply made and the barrel-type jacks and plugs don't make solid electrical or mechanical connections. If they had used 1/16" phono plugs and larger balls with tighter jacks and a better quality of plastic, they would have had a first class product. It is a fascinating product that could have been better made, but I certainly would not recommend this for children liable to put the small pieces into their mouths.
