Please Help Me! I'm uncreative and need help with my chemistry project!

I have to make a poster for my chemistry class displaying a safety rule. This is very hard for me because I am so uncreative that… I can’t even think of an amusing analogy to show how uncreative I am. I don’t want to come off as lazy, I am a good student, but I need a little help here. The poster has to be the size of half a poster-board or so, and illustrate a safety rule for chemistry lab. The example me teacher showed said, ”keep long hair pulled up” and had two pictures, one with a girl at a lab table with long hair hanging down with an “X” drawn on the table and another with the girls hair in a ponytail, but this one with a green check mark on the table. A few examples of rules would be:

-Always wear your safety goggles

-Never leave Bunson Burners unattended while On

-Add Acid to Water, not Water to Acid

Any startup ideas would be appreciated.
