Do you have to keep bread wet if want grow mold on it?

It is not necessary to keep bread wet to grow mold on it, but providing moisture can speed up and enhance mold growth. To grow mold on bread:

1. Acquire Bread: Choose a few slices of bread that are a few days old and have gone slightly stale.

2. Moisturize the Bread: Lightly spray or brush the surface of the bread with water. This increases humidity and creates a favorable environment for mold to grow.

3. Place in a Warm and Humid Area: Place the bread slices in a warm and humid environment, such as a covered container or plastic bag. This can be achieved by leaving them on a kitchen counter or in a closed pantry.

4. Darkness: Mold thrives in the dark, so keep the bread slices in a location away from direct sunlight.

5. Wait: Mold typically starts to appear within 24 to 48 hours. As it grows, you'll notice white or greenish-gray fuzzy patches on the surface of the bread.

While added moisture accelerates the mold growth process, it's not essential. Mold spores are naturally present in the air and on food surfaces, so even if you don't intentionally introduce moisture, mold can still develop over time, given the right conditions.
