The answer to last week’s challenge is. Q: You are inside a perfectly cubical room where each wall, the ceiling and the floor are mirrors. There is nothing else in the room. How many reflections can you see if you’re facing in one direction and can look up, down left and right?

A: None. Within the cube there would be total blackness given the walls, ceiling and floor are mirrors and completely opaque. No light would be able to penetrate to enable any reflection.

This week’s thinking challenge is.

Q: A man staggers out of a pub under the influence. Everything he is wearing is black, including a ski mask as it is very cold. He is walking down the middle of a road with no shops or street lights. A car is speeding toward him with its lights off but somehow manages to stop in time. How did the driver avoid hitting the man?

The answer to this and a new Mental Floss will appear next week.
