I have a 5-year-old boy who's very into electronics and Ghostbusters in particular. So far, I've had pretty good luck with snap circuits.
We started to build a homemade Ghostbuster Proton Pack but it only sounds exciting to him in theory, he'd rather play with the wire cutters then work on the project.
Any recommendations on projects or kits that might be more compelling, holding the attention of a 5-year-old for longer?
