What's the longest straight line you can sail on earth?
Apparently it's almost 20,000 miles from Pakistan to the Kamchatka Peninsula in Russia, via the Indian, South Atlantic and Pacific Oceans.
I know it doesn't look like a straight line on the Mercator projection, but check out the video.
I wonder how long it will be before someone actually tries to sail it?
