Sore Heid Warning: The following is likely to burst your nut.
Imagine a football ... a regulation size SFA standard football.
Now imagine wrapping a ribbon round it, nice and snug - so snug you cant fit your fingers under the ribbon.
Now cut the ribbon so that the ends of the ribbon, when glued together, just touch and no more leaving a tightly wrapped ribbon around the equator of the ball. Now cut the ribbon and add a metre of extra ribbon to it and glue together as before.
The ribbon is now slack.
If you were to place spacers all the round the equator of the ball in order to wrap the extended ribbon super snugly as before around the ball but keeping the ribbon the same distance away from the ball (ie
the height of the spacer) all the way around the equator then the spacer would be 16cm tall. That is the distance from the surface of the ball to the underside of the ribbon would be 16cm all the way around the ball.
Now imagine the earth, diameter 24,901.55 miles (40,075.16 km) at the equator. Assume for the sake of argument this value is 40,000 km.
Repeat the ribbon wrapping procedure around the earth (assuming a smooth surface to the earth - I know what HG pedants are like) and make it tight.
Cut it so the ends just meet as before then add an extra 1 metre, just the same way you did with the football and once more glue the ends together.
How big do you have to make the spacers this time in order to ensure that the ribbon has the same gap all around the earth's equator and is wrapped as snugly as the ribbon wrapped round the football?
I like him ... He says "Okie Dokie!"
