Color Changing Spoons

Today is colour changing day (see below). These spoons change their colour depending on the temperature of your microwaved meal. You simply put the spoons with the dish into the microwave and when it comes out, you will see, whether your soup is hot or not. If it is too hot, you can just wait till the colour changes, and you finally won't burn your tongues.
