My ph checkers

The first time around my cotton buds weren't all that dark though when I checked them with salt or vinegar they definitely turned blue for alkali and reddish purple for acid. Maybe i didn't bruise the cabbage enough after cutting it up or maybe I was a bit mean on my ration of cabbage to methylated spirits. anyway. I cut up some more cabbage and reapplied the stick and now they are a nice deep purple colour, dry and contained in a plastic container waiting for me to test the ph of the water I use in eco or extraction dying
