I made my first youtube animated video. You can learn how to count to 12 on your fingers, to 60 and even to over 1000 using the binary system. It explains why we have twenty-fours in a day, sixty minutes in an hour and sixty second in a minute. It all makes perfect sense when you know why.
You can view it here.
I’m planning the next animated video on rainbows and colour. Did you know why there are thought to be seven colours in a rainbow and why they are the wrong seven?
