The Nose Test is a funny and noisy conductivity activity which adults find just as funny as kids. Participants hold on to the Buggy’s robotic arms and then ‘test’ each other’s noses with a gentle squeeze, passing a (very low) current and so producing a variable squeak and a guaranteed smile. This simple interaction can extend from a couple to a family to large groups of 20 or more. It can last for around a minute if a couple of people want a quick laugh, or be built into a 15 minute mini-show if a crowd gathers. In this case we build up the dramatic tension and also go into the science a bit deeper. We then test carrots, dogs, spoons and anything else people can offer (as well as our own random assortment of test objects). Once tested, everyone gets a (highly coveted) ‘Nose tested’ stamp.
