There was an episode of QI where Stephen was playing with a device where you point its directional microphone at someone, and it plays their voice back with a slight delay making it very difficult for them to speak. The guests had to try to read a children’s book aloud while he pointed it at them. None of them except Alan could do it.
I would like to buy one of those devices lol.
Has anyone ever tested those red hats for lead content?
