How can we keep teacher's tea hot?

Mrs Clarke came to us with a problem. Her tea was always cold! So we devised an experiment to find out which material best insulates her mug. Most of us thought that cotton wool would work the best but we were surprised to find that putting a lid on the mug was actually the best insulator! 
Now Mrs Clarke can enjoy a nice hot mug of tea after yard duty.
