Here’s another idea for a box item. We’ve had these Snap Circuits for a few years now. They are a great electronic toy. Remember using wires with batteries and hoping all the circuits were complete? With this set, it isn’t so finicky!
They are all built on this base and the pieces are color coded. the pieces literally snap onto each other so there’s always a good connection. The tricky part is building the circuit correctly. It has a place for the battery packs and you can switch them out easily, but I noticed the other day they sell an AC adapter for the sets. That might be worth getting.
You can find these at Amazon and other places on line I’m sure. These were a gift from my in-laws, but Rainbow Resources carries a full line.
Snap Circuits are a great learning tool and a lot of fun!
