What happens if you put silly putty in the sun?

When you put Silly Putty in the sun, it can become warm and soft due to the heat. Prolonged exposure may cause it to lose its elasticity and stickiness, making it less bouncy and more gooey. Additionally, UV rays can potentially degrade the material, leading to discoloration or a change in texture. It's best to store Silly Putty in a cool, shaded place to maintain its original properties.
