Thames & Kosmos Electricity & Magnetism kit teaches real circuits — just budget your patience

The Thames & Kosmos Electricity & Magnetism kit is the real deal — it teaches actual circuits, not toy versions of them. But you need to budget your time and patience before you open the box. The experiments are legitimately educational, which also means they require adult involvement, some setup, and a tolerance for the occasional frustrating step. If you’re ready to sit with your kid and work through it together, the payoff is great. If you’re looking for something they can do solo on a rainy afternoon, keep looking.
