Coming Soon 👀 At the beginning of April, you’ll be
introduced to a brand-new GoComics! See more information here. Subscribers, check your

Standing wave patterns. I didn’t watch it, but saw a youtube video promising to measure the speed of light with chocolate (assuming the frequency of a microwave oven is accurate).
There’s a neat experiment you can do to see how it uses a standing wave to heat the food, and why you get hot spots.
Put a plate of cheese into the microwave (remove the rotating tray first if it’s got one), and run it long enough that the cheese just barely starts to melt.
You’ll get lines of melted cheese with unmelted in between. The distance between the melted lines is the wavelength of the microwaves.
Constructive interference of the micro waves causes hot spots, destructive interference causes cold spots. Just ask any of the 8th graders I teach. No wait, don’t ask, they had their test over a week ago. ;)

So that’s what happened. I wasn’t a lack of quality control. It was a matter of apathy. ‘Good enough’ over ‘six sigma’.

from what I’ve noticed, the handle is usually on the other side of the door?

And, just for giggles and grins, let’s put in a blinking LED light that always reads: 12:00!

Had one that always left a frozen circle right in the middle of the pizza. Now I use a toaster oven for that.

I like the pyrotechnic effects when you put metal in it too.
