The Thames & Kosmos circuit kit makes Dad feel smart again — and the kid actually learns

There’s something pretty great about a science kit that lets Dad feel smart again while the kid actually learns something real. The Thames & Kosmos Electricity and Magnetism kit delivers exactly that — it’s challenging enough that you get to dust off your high school physics knowledge, but hands-on enough that a curious kid will grasp the concepts without a textbook. We spent an afternoon building circuits and both of us walked away genuinely satisfied. That’s rare.
