Mental Floss 329

The answer to last week’s challenge is: Q: There is a chain nailed to a wall. The chain is 3 metres long and the middle of the chain dips down 1.5 metres from where each side of the chain is nailed to the wall. How far are the 2 ends of the chain from each other?

A: No distance apart because both ends are hanging from the same nail.

This week’s thinking challenge is …

Q: What number do you get when you multiply all of the numbers on a telephone’s number pad?

The answer along with a new challenge, next week.

Have an excellent weekend!
