If you need pH test strips for Chem Lab or to test your tap water or water on the go, or even yourself, this litmus paper roll by Sonkir is perfect.
The paper roll comes in this awesome dispenser that is a little bigger than a silver dollar and has the chart tight up on top. You can rip off as much paper as you want. We have been testing soda, water, saliva, etc and it's just silly fun. The hubby is acidic and blaming it on mountain dew!
