Have a guess! (brain teaser)
Imagine pulling a rope around the globe (which is a perfect sphere) and tensing the rope tight. Now you add 10 meters to the rope and distribute the rope around the globe so that it is equidistant from the globe (see sketch above).
➽ What is the distance x between the globe and the rope?
➽ Do you think it is enough height for a fly to crawl down through?

Answer:
In the calculation above you can see that the distance is 1,59 m!!

And the astonishing point is: You can do the same with an orange (fruit) and it will give the same result!!
Well, mathematically not really remarkable, but imaginatively it's astonishing! :-)

... and there is an additional point that you may have noticed: on the globe above GB is missing. So the Brexit also is solved! ;-))
Due to several complaints I have reinserted the British Isles. ;-))

By the way:, have you also noticed that longer texts are no longer completely translated by the translator?
