I like random facts., here’s one.
If you had a piece of string long enough to cover the circumference of the Earth, how much more would be needed for the string to be one metre above the earth?
Answer - Approximately 6 metres.
Same premise with wrapping the string round a tennis ball, how much more would you need to be one metre above the tennis ball?
Answer - Approximately 6 metres

I knew about the earth one but not the tennis ball one.
Simple maths really.
It will always be approx 6 metres, whatever the sphere.
C=2πr
So 2 x π = 6 ( for ease of calculation. Yes we know it's a little more)
So if you increase the radius by 1, the circumference must increase by 6.
Genuine interesting though.
Thanks @tomgoodun
This may be the reason that the employees get given a bottle every month as they would have to leave the County Lines in order to legally by alcohol.
That's a bit like banning the sale of alcohol in Burton on Trent.
The 9 times table, everything multiplied by 9 adds up to 9,
9x9 = 81, 8+1=9,
9 x 13 = 117 , 1+1+7 = 9
9x99 = 891 , 8+9+1 = 18, 8+1 =9
