Project Idea: What is the pH of…?

It occurred to me that I don’t have a good idea what the pH of certain things are. I know Coca Cola is highly acidic, and that vinegar is quite acidic. I know the pH range of rainwater, common laboratory chemicals, soils, my aquarium (and so on). But there are also a lot I do not know. So perhaps it would be a good idea to start a collection of pH values based on contributions from the students. I could equip them with pH paper (standardize the method) and have them spend a half day going around measuring the pH of anything that catches their curiosity.
