They make you wear safety gear doing perfectly safe experiments at the beginning so you get in the habit of wearing it. Then they know they can count on you to wear safety gear when.doing really dangerous experiments involving chemicals like sulfuric acid. Sulfuric acid can eat through your skin in seconds.
Disney should have done this in the episode of "Cars on the Road" where Lightning McQueen and Mater stayed in a haunted hotel. They should have taken a Ferrari 360 Spyder or a Mitsubishi Eclipse Spyder or a Porsche 918 Spyder and given it spider legs and had it crawling around the hotel. What a missed opportunity.
