# Only a few geniuses can solve this drinking glasses challenge

Touching only one of the glasses

I got this next puzzle sent to me by a colleague, and it took me a long time to figure it out.

The challenge itself is the following: you must empty every other glass – but you can only touch one of the glasses at a time. Below we can see the picture.

Answer: you take the second glass from the left and pour it into the fifth glass. That way, we have the following pattern of glasses: full, empty, full, empty, full, empty – in other words, every other glass will be empty.

Bonus challenge

Okay, we’re going another round now that we’ve warmed up. This time, a math problem will be shown below.

Karen has four daughters. And every daughter has a brother. How many children does Karen have in total?

This one is quite tricky and requires some concentration. Do you have an answer ready? Below, we present the solution.

The answer: 5, all the daughters have the same brother.
