The All-Red Route 100 Years On

An anonymous reader writes "On October 31, 1902, the first messages were sent along the All-Red Route -- a 5500km telegraph cable linking the whole of the British Empire. First envisioned in 1879, the long-decomissioned cable is still regarded as the longest single run of cable in the world."

Lubricant works simply because it doesn't allow two surfaces to come into contact. When lubricant is used between two moving surfaces, a "wedge" of the substance forms, and the moving surfaces literally float on this "wedge".

The effect is even more pronounced in a rotational context, but that's not often the case in sex, unless you're into acrobatics or using a dildo.

Good luck with your studies!
