Open-toed shoes
you should put your hair in a ponytail and wear safety clothes
You should first apply Spray and Wash to the lab coat and then try to wash it. If this does not work, you may have to send your lab coat to the dry cleaners in order to get it clean.
You should tie up long hair in a science lab to keep it from dragging through your experiments, or being lit up by a Bunsen burner.

The word Lab in the terms of science (not the dog) is Laboratory.
in my opinion you should tell the teacher immediately
