How do microwaves work? | Live Experiments (Ep 7) | Head Squeeze
243Jon Chase uses chocolate to explain how microwaves work.
Recipe
IMPORTANT: You will need one sober adult with a sense of scientific wonder....
What you need to get started is: A microwave, carboard and a large bar of segmented chocolate.
1. Take the revolving dish out from your microwave (It's important that you do this for the experiment to work).
2. Now cut a piece of cardboard to size, so that it fits the base of your microwave.
3. Break your bar of chocolate into 12-20 segments and spread them evenly on your piece of cardboard.
4. Heat the chocolate for 1 minute in an 800w microwave. You may have to adjust the times if your microwave is lower or higher than 800w (The key thing is that you don't let the choclate burn).
5. Now take the chocolate out from the microwave.
6. Use your finger to press down on the pieces of chocolate and you will notice that some pieces are solid and some have melted. This is because microwaves do not travel from left to right but go up and down. This is why we use a revolving dish to evenly heat our food.
