## Resource

CrowdScience listener Doug has been experimenting with holding his wireless garage key to his chin. Why? Because he's testing a strange trick of physics. The range of a key can apparently double when held against your head rather just being held in your hand. Could this really be true, and if so why? Presenter Caroline Steel goes on a wavy journey of self-experimentation with antennas. She follows the story of Doug as he wanders the streets of Calgary in Alberta, Canada testing the key on his head from different distances and even testing it on his dog Maura’s head. To understand the physics behind all this, Caroline meets Dr Lina Mohjazi, Lecturer of Autonomous Systems and Connectivity at the University of Glasgow and Guy Vandenbosch, Professor of Electromagnetic Radiation at KU Leuven University in Leuven, Belgium.
