Can I unlock my car using my head?

CrowdScience listener Doug has been experimenting with holding his wireless garage key on different parts of his body. Why? Because of a strange physics phenomenon that means the range can double if you hold a key to your head.

In this episode, Caroline Steel joins in the self-experimentation to find out which body parts boost range the best. It’s all to explore why our bodies can act like antennae. With some encouragement from listener Doug, she’s also exploring whether the same physics could boost your wifi signal (if you were willing to take turns putting your head on the router).

Join Caroline Steel as she goes on a journey to unlock the wavy secrets of the humble remote key.
