Recently the Children's Room hosted a Tinkering Tuesday that focused on electronic Mother's Day cards using conductive tape, a 3V battery, and a LED. The goal was to make something extra special for mom while learning about simple circuits. Science = Fun! I had practiced on a few cards beforehand experimenting with conductive paint and tape but only 1 LED. I had no problems except when using the paint (which I made myself). It takes a while to dry and it won't light up until it is. Honestly I'd recommend the already made paint from BARE instead because the graphite I used to mix my own was expensive and unreliable. Due to drying times, I concluded that the tape would be the easiest option available for our 1 hour program. I had gone into this feeling rather confident that we could tinker around and I would not limit the kids to certain design principles when making the circuit. I was quite surprised by the amount of difficulty and frustration the kids had felt...
