Answer 1

You don’t need theory for something to work.

Heres how a science theory comes to existence:

1. someone see something happening, in nature or artificial.
2. they wonder how it happened.
3. they come up with a hypothesis.
4. they test it out with experiment.
5. they create a new theory once the experiment shows support.

You can leave it at step 1, step 2~5 is not required to replicate the product.

If someone left the oats in water because of procrastination and led to spicy water. They don’t need to understand the mechanics behind that to recreate the process.
