There are some old photos at home, which are stuck together because of the wet weather. How can I separate them?

Soak the old photos in water. When they are completely soaked, the photos can be slowly separated. Don't forcibly separate the photos to avoid damage.

Never use a light bulb to dry it, the more it dries, the more sticky it becomes.

You can wet two useless photos with a little water and stick them together. When they are dry, they will stick together. Then try it with blisters.

The separated photos can be dried with steel plates, and the surface is smooth and stain-free.
