What happens when you put blue tack in a fridge?

Blue tack is a reusable adhesive commonly used to stick notes and light objects to surfaces without damaging them. When you place blue tack in a fridge, the cold causes it to harden and become less adhesive. As a result, it may no longer stick as effectively to surfaces, and its tackiness may diminish. The same effect can occur if you expose blue tack to low temperatures for an extended period.
