Interesting. I will have to give it a try.

That is interesting. However, I still recommend using a liquid test kit to test your water. Contacting your local water company may be better, because they have the exact readings.

That is super fun! I've done this with kids for years. It's a great way to introduce them to the concept, and makes it all so accessible. And there are more colors than an API test, too!
