Morse Code
It's not much of a "kit" - add a battery and use the alligator clips to make the connections. It might take younger kids all of five minutes to figure it out unassisted.I used this for a demonstration of Morse code at a scout event. The wires were a bit too short - younger kids couldn't get to the lever without hitting other pieces. It became a two-person demonsrtation - one older scout holding the other pieces while the younger tried to make the connection that would trigger the light. The lever that triggered the light is not designed for light touches - the kids had to mash it down for the light to work.An insert with a brief history of Morse code would have been a useful addition.On the other hand, these operate silently unlike the buzzer style code keys. After four hours of this, you learn to appreciate the little light.

not good
After reading the previous review, I decided to take a chance. After all, I only needed this to work for two hours. It turns out he was right.My son did a project for a CSA Expo on Samuel Morse and his Morse Code. This only worked part of the time, and then only after a lot of messing around. We threw it away as soon as we got home, so we ended up wasting the money we spent on it and the battery.At the same time, though, we bought a set of cardboard signals for $3.00 here on Amazon, and they were actually fun. Who knew?
