When I was about 10, for whatever reason, my mum believed that I thought weather forecasters presented the weather on TV from a spaceship that looked down on earth. So, she told me that the earth behind the weather presenter wasn't actually that big. But, unknown to her, I knew they were in a studio with a computer screen behind them. So from then on I believed that the map behind the weather presenters wasn't actually there - it was a tiny screen that was magnified just for us and the weather presenter couldn't actually see the magnified version. They just had to guess where to point to on the map.
