Hello.
We are going to do an experiment for CrowdScience today.
We're going to go on a walk with my dog, Maura.
Come here, Maura.
Sit.
That's a good girl.
Maura is a championship wheat and terrier.
She will do just about anything for a treat.
So she's a very willing participant in this experiment.
This is CrowdScience from the BBC World Service, the show that answers your science questions.
I'm Caroline Steele, and the owner of today's Very Obedient Terrier is listener Doug.
I'm Doug Brown, and I'm calling from Calgary, Alberta, Canada.
Doug emailed into CrowdScience because he has a question about some strange behaviour from wireless keys, keys
that open something like a car or garage from a distance, or as Doug likes to call them, fobs.
My question for crowd science is that I recently heard
that holding a car fob to your chin will extend its operational range.
And I was just wondering what the physics was that was going on with this.
Interesting.
OK, so you say you heard that holding it to your chin doubles the range.
Where did you hear that?
