How Must The Painting Be Hung
Riddle: You have a painting with a string attached to it. The string is attached to the upper two corners of the painting. In the wall there are two nails, horizontally next to each other. The string must be hung on the nails in such a way that the painting falls down if any of the two nails is pulled out of the wall. The painting must hang under the nails and must hang on the string.
The Question: How must the painting be hung?
Answer: 
To solve this, loop the string around each nail twice in a criss-cross pattern, ensuring it hangs below the nails. First, loop the string around the left nail, then the right nail, then back to the left, and finally to the right, and attach the ends to the painting. This creates a configuration where each nail has two sections of string supporting it, but removing one nail will cause all the tension to shift, causing the painting to fall.
