Lions in Cages

Friday, October 9th, 2009 When we were spinning our colour wheels last week we noticed that if you spin things fast enough your eyes might not be able to keep up and you migh see something that is not actually there! Teacher had pictures of lions and cages, and prisoners with cages. We cut them out, stuck them on our pencils and spun them. When they were spinning quickly it looked like the lions and the prisoners were behind bars. This happens because our eyes can't send messages to our brains quickly enough for our brains to realise that we are looking at two different pictures, and not just a single one.
