Acid

I don't really understand acids but I know they are bad for you, like don't eat batteries.

I got an acid tester called a pH test. We bought it at the test tube store.

I put a few drops of every kind of water in these tiny bowls.

And then I put these little pieces of paper in the water and they changed colors.



The lagoon water turned the paper green. Probably because of the alligator tinkle.
And the Atlantic Oceana and Pacific Ocean water is a little bit darker than the others. I think this is because more fish swim in it.
