“First you find a large field” I began “it has to be really big, even bigger than the swing park. Place a football in the middle of the field to represent the sun”
Junior nodded thoughtfully.
“Now take ten big steps away from the ball and drop a pea. That’s Mercury. Take another nine big steps and drop a peppercorn for Venus. Seven more steps and drop another peppercorn for Earth”
I continued to explain the entire process right up to (the recently demoted) Pluto which would be a small pinhead about half a mile away from the football.
Junior looked utterly engrossed as he stared up at the sky with a look of intense concentration on his face.
Great! He’s really listening to this; I’ve got him eating out the palm of my hand.
"Mummy" he said when I finally stopped to draw breath.
He’s going to ask me a challenging question! I thought with a satisfied smile or offer me some of his own knowledge on the subject.
“I’ve got a really itchy bum”
Perhaps it might have been better if I had just shown him this wonderful video on YouTube.
