This is the kit featured in our TED talk. We use it as a way to teach about the nervous system and how electrical impulses are used to both receive and send signals!
Great for demos and DIY experiments, but more importantly this tool creates so much hype and excitement in a classroom that it gets students asking questions, wondering what else is possible, and more importantly, excited to see what they can create. Outreach Example.
The kit is very portable, easy to share between classrooms, and easy to use.
