Demonstrate conductivity, connectivity and electrical currents.

The energy stick flashes and makes a sound when both metal connectors are touched. Use it on your own or join together in a group to create a human electrical circuit! In order for the Energy Stick to activate, each of the two foil ends must be connected by something that conducts electrons to flow through it. What else could it work with? Stick measures 16 cm in length and comes complete with non-replaceable batteries.
