When I was in chemistry class the teacher was discussing heat and work and how heat is changed to mechanical energy, so I made a cutaway of a Briggs 4 stoke and a Power Products 2 stroke engines and mounted them on a display board. I brought it in so the class could see how they work.
Now, the bad news.......
To my surprise, the next day the teacher had the news crew come to class and take my picture and he thanked me for GIVING this display to the chemistry class for keeps. What could I do!
