At least you don't have a crazy chem teacher.

Unfortunately, she managed to make us think of this:

Thank you I am aware of that. Well tbh I am surrounded by crazy people in my chem class. We were talking about the surface tension of water, then we talked about how the water strider insect could walk on water, then this kid in my class started speaking about how Jesus (AS) walked on water...and she was answering him...
