My partner is a teacher. She recently took the solar Cokit in to her class (year 6) and cooked for the entire class. She served up cherios (small hot-dog like sausages with the red skin). The children were amazed at the temperatures it got to, and other teaches said it would be a life changing experience.
Importantly I printed out some signs: "Danger HOT" and "Warning Hot Surface" signs. We got the pictures from the internet, printed and laminated them. I've stuck them to the oven for when I use it at work - better safe than sorry.
