Wait... wait... wait...
You haven't put a CD in the microwave yet? Seriously?
Man, go do it. It's awesome fun. Creates a very pretty light show, makes a weird ozone mixed with burning plastic smell and creates a beautiful pattern, which if you are like me, leaves you wondering why the pattern is the shape it is.
No longer than 5-10 seconds. Put it, on high, hit START and wait until you see the first light show, say, 1000, 2000, and hit STOP.
Your CD is ready.
If you want to freak people out at a party, try this one...
Fill a glass of water half way. Put a normal incandescent bulb in the water, make absolutely sure the water covers the metal fitting completely, but only the metal fitting. Put it in the microwave on high, hit START and the light bulb will light up. It even works with blown light bulbs.
It's 100% mostly safe.
