Ph water testing without a kit using red cabbage

If i remember right iodine can be used
That is a neat alternative but with PH test kits available for under $3 you might be better off eating the cabbage

I was going to say
Cabbage $4
pH drops $9
But it’s the same point. It is a neat idea though.
And I hate cabbage.

Don’t forget to add the cost of buying the distilled water required to boil it in. It’s a neat idea for some I suppose depending on where you live. You can distill water and get the cabbage from your garden.
Distilled water only costs a $1 in my area.
