I actually purchased these for experiments with the kids.
It's a great way of them testing and understanding the varying pH's of different liquids e.g. vinegar, milk, cola, water, saliva.
Easy to use just take a strip from the box and dip into the liquid, it only takes a couple of seconds to see the results which you then compare against a colour chart.
Personally I use to test acidity in urine levels so I can keep track and balance out if need be.
