Did you know that your ears can't hear things that dogs' ears can? Winchcombe Science Leaders are bringing some new activities this year, including one to show the kinds of sounds that human ears can't pick up.
You'll also be able to map your retina (that's part of your eyeball), test your reflexes, and check which parts of your body are best at feeling a pinprick.
And if you think you have clean hands .... well, wait and see. There'll be a machine that uses ultra-violet light to reveal microbes on the human body. Surprises ahead!!
