Thank you so much to Mr. Cunningham for his explanation of his job as a heating engineer to P2A this morning.
He really made the boys and girls think about the fact that the jobs we have today may be very different tomorrow when they are ready to choose a career.
We especially liked cracking the metal in the packet and watching the clear gel turn white. Then it heated up our hands. When it began to cool down again it became rock solid. The heat pack could work over 40,000 times. This is a type of battery and is more energy efficient than many batteries we use in our gadgets. It is more sustainable.
We thought that it was amazing that the ingredients pumped into the heat pack batteries were salt and vinegar!
What will we be using when we grow up to create Sustainable Energy?
