If you’d like to learn about the basics of electronics, or teach others how an electrical circuit works, then this solderless “Don’t touch the wire” maze kit looks like a great way to get started. The game involves moving a conductive washer from one end of a curved length of wire to the other without actually touching it. One large diameter washer is included, which looks challenging but doable, along with a smaller diameter washer that would certainly be more frustrating.
When playing the game, each washer is connected to an alligator clip, allowing it to complete a circuit when it touches the wire, then sound an alarm to indicate an error. The kit comes with the needed wires and a 2AA battery holder, along with lever nuts that allow builders to snap everything together securely without the use of a soldering iron.
While one would want to avoid getting snapped by these connectors, not having to deal with a dangerously hot soldering iron would eliminate an important barrier to early electronics experimentation. The kit comes with instructions, and after one builds the kit (and learns about completing a circuit) it can function as a fun toy and conversation piece!
