I get bored sometimes. Sometimes I do productive things with that boredom, like learn another language. Sometimes I stick things in Microwaves that perhaps isn't food and don't belong there.
Did you know that if you stick Christmas Lights in a Microwave at Full Power for about 10 Seconds, that they light up in different colours, even if they are a sting of White Lights? Check it out....

This would be a fun science experiment for school credit if somehow I could figure out why they turn different colours.
