How do you make mold grow on yogurt?

Mold naturally occurs on many fermented foods, such as yogurt, as a result of exposure to airborne mold spores during the fermentation process. To effectively encourage the growth of mold on yogurt, follow these steps:

1. Preparation:

- Start with plain, unsweetened yogurt.

- Divide the yogurt into small portions.

- Transfer each portion into separate shallow containers or petri dishes.

2. Create a Humid Environment:

- Create a humid environment by adding water to the bottom of a larger container or plastic box.

- Place the containers or petri dishes with the yogurt portions inside the larger container.

- Close the container or box to trap the moisture.

3. Introduce Mold:

- Expose the yogurt to mold spores by leaving the container open for a few minutes in an area with potential mold sources (such as a garden, compost bin, or near damp areas).

- Alternatively, you can also introduce mold spores by adding a small piece of moldy bread, fruit, or cheese to the container (place it on a separate surface, not directly on the yogurt).

4. Monitor:

- Keep the container closed to maintain the humid environment and check the yogurt regularly for mold growth.

5. Wait:

- Mold growth can take several days or up to a week or so to become visible.

- Once mold starts appearing, you can continue to observe its development for educational or scientific purposes.

Note: When working with mold, it's important to practice proper hygiene and safety precautions. Mold spores can be harmful if inhaled, so it's best to conduct this experiment in a well-ventilated area.
