Never changed color, waste of money and time, and it ruined my lesson plan.

Did not change color
I tried to use this for my class to show chemical change and it would not react. Never changed color, waste of money and time, and it ruined my lesson plan.

Not real
This item was horrible. I’m not sure it’s actually bromothymol blue. I tried to use it for a biology class experiment and it didn’t work.
