Circumference of the earth
I was doing my science lab, where we had to calculate the circumference of the earth using the distance of two cities and the time differences. I didn't realise the Circumference of the earth to be so small. I got a figure slightly larger than 40000km. It takes 7000km of driving experience for an army driver to obtain his license. Most of the drivers I know clock in a good 13000 to 15000. Wow, the earth is a small place.
