I made my own little light show with the LightUp Edison Kit (lightup.io). At first I thought the cord was to light up the circuit but I found out it was for charging the battery. I went on the LightUp learning app which helped me a lot. The project was to make light with the battery, wire, buzzer and switch. First I turned on the battery and I connected all the pieces. The lights flow better with the wire. I took a picture with my iPad of the lights flowing all around the circuit. This was a really cool experiment to do. I found it to be a little hard at first but thanks to the LightUp app, it made it a little easier. I recommend you try this kit. I think it is educational and fun at the same time.
