Personal Comment: This pretty easy but there is an unexpected twist...

The Snail and the Well Enigma!

What we know: A snail is at the bottom of a well 30 feet deep. It crawls up 3 feet each day, but at night, it slips down 2 feet.

Enigma: How long does it take for the snail to crawl out the well?

Solution: 28 days. Once it reaches the top, it does not slip down 2 feet.

See who got this right
