## to test soil pH:
vinegar + soil ==> bubbles == basic
baking soda + soil ==> bubbles == acidic
I wonder if I could use ashes to test if acidic instead of baking soda.
can also use the purple cabbage method, but I don't have purple cabbage.
if I can find a way to preserve them properly it might be worth it to grow some just for pH testing.

## to modify soil pH:
vinegar or coffee grounds to make more acidic
ashes to make more basic

## soap:
ashes and animal fat.. TODO: elaborate on this recipe. (and actually test it)

## vinegar:
TODO: look up a good way to make a bunch of vinegar easily
