What is a PH strip?

W.A.L.T use a ph strip so we can see if some drinks have acid in them or not. Also we put one egg in each container  so we can see what happen over time. When we came to check on them the red bull creak the shell so that mans that red bull has a lot of acid in it.

here is some photos of what has to the eggs and we will continue this process
