Day 130. You can't handle the truth.


The Hot Wires lie detector. This is a great kit for kids teaching them the basics about circuits, not just  tools to test the trust worthiness of family members. This one works from moisture on the finger plate - assuming that if you're lying you're more likely to be sweating. It was a last minute addition to an already long Christmas list but one I'm glad we bought.
