701. Why Do Antiseptics Sting When Put on Cuts?
The answer has to do with ethanol and hydrogen peroxide, which are often ingredients in antiseptics. Both of these agents activate receptors in the body that trigger a burning sensation.
Ethanol activates the vanilloid receptor-1, known by the nickname VR1, according to a 2002 study in the journal Nature Neuroscience. VRI is responsible for creating a burning sensation when it's exposed to heat or certain chemicals, such as capsaicin in hot peppers.
VR1 is typically activated only at high temperatures, about 107 degrees Fahrenheit (42 degrees Celsius) or higher. "Usually it's not turned on unless you're actually getting burned,".
However, when ethanol comes into contact with the receptor, it lowers the temperature threshold to below body temperature. "So, all of a sudden, you feel like you're getting burned, even though you're not getting burned,".

700. What is the True Purpose of Solitaire, Minesweeper, and FreeCell | Mental games in Microsoft OS?
Microsoft Solitaire debuted in Windows in 1990 when the software giant rolled out version 3.0 of the operating system, and it was the first widely-popular digital version of the card game (although it actually existed since the 1700s, but in traditional form).
And as it turns out, Microsoft had one very clear goal in mind when bringing Solitaire in Windows: to teach Windows adopters how to use the mouse and drag and drop features. As weird as it may sound, at that point, the mouse was still an unexplored world for most computer users, mostly because the majority were used with the traditional command line.
So Solitaire was there to make the whole mouse thing a familiar experience, and judging from where the mouse is right now, Microsoft’s plan was kind of successful.

699. What is Sailing Stones?
The mysterious moving stones of the packed-mud desert of Death Valley have been a center of scientific controversy for decades. Rocks weighing up to hundreds of pounds have been known to move up to hundreds of yards at a time. Some scientists have proposed that a combination of strong winds and surface ice account for these movements. However, this theory does not explain evidence of different rocks starting side by side and moving at different rates and in disparate directions. Moreover, the physics calculations do not fully support this theory as wind speeds of hundreds of miles per hour would be needed to move some of the stones.

698. What is Iris scanning used for?
Iris scanning technology is a security measure used to identify individuals with respect to high-security applications, such as government buildings, airports, computer access, ultra-secure locations and cellphone access. Hospitals use iris scanning technology to pair mothers with infants in maternity wards. Border crossing agents match the identities of people on government watch lists with iris scans.

695. What is OK short for?
The most popular theory is that OK comes from ‘oll korrect’, a deliberately misspelled writing of ‘all correct’. It was popularised in Boston newspapers around the 1840s when it was fashionable to go around spelling things incorrectly for humorous effect. Legend also has it that New York Democrats later adopted the abbreviation to promote their candidate Martin Van Buren – the initials ‘OK’ were derived from his nickname, Old Kinderhook.
It has been described as the most frequently spoken or written word on the planet.
