There has been a lot of debate about what the most amazing invention of all time is. Some say the wheel. Others say the microprocessor. Mere amatures if you ask us. Pretenders in a space reserved for the truly amazing. They can't compete at all with the thermos. Laugh if you will. As you know, a thermos keeps hot stuff hot and cold stuff cold. But have you ever stopped to wonder how it knows which one to do? Admit it -- Never once has a thermos kept your hot coffee cold. Simply Ingenious.
