But no one who has heard an oxy-hydrogen soap bubble explode in a lecture hall can ever doubt the value of stoichiometric calculations. Do you believe that the Apollo moon rocket ran on diesel fuel, just like a truck? I can show you an experiment that will make you believe it could as easily have run on bacon.
Teachers should be able to do this kind of science, and many would love to, but cannot because of the fear of what would happen if there were ever an accident. A student suffering even a relatively minor injury from a dangerous chemical would be front page news anywhere in the U.S., even if the same student spending a week in the hospital due to a sports injury would go completely unnoticed (unless perhaps he's the star quarterback).
The science teacher would likely lose their job, while the coach would be offered condolences on the loss of their star player.
