Here is a fun brain teaser from puzzle master Wes Carroll.

Tipping the Scales

Question:
The top two scales in the image at the right are in perfect balance. How many diamonds will be needed to balance the bottom set?

This puzzle helps you work out your executive functions –supported in the frontal lobes— by using your pattern recognition, hypothesis testing, and logic.


ANSWER:

Four diamonds

SOLUTION:

First add up the number of clubs in the first two scales (5). Then count how many clubs are in the bottom scale (5). The do the same with the spades, which gets you 5 and 5. There are 4 diamonds in the top two balanced scales. Therefore, it must take 4 diamonds to balance the third scale since all the other measurements are the same.

Glossy Legs Leave Internet Agog (Scientific American):

“…A young artist has posted a picture of their legs, which are impossibly encased in shiny shrink-wrapped plastic. Or are they? The more you look at it, the more likely you will realize that the shell is not plastic, but rather bare skin with a few streaks of carefully applied white paint. And for many of you, it will then switch back to plastic again!”
