I did this with my kids a couple of months ago, using chocolate. It came out about 290000 km/s. Lots of fun explaining it first and then using Google afterwards

Apparently you can see plasma, if you microwave a light bulb in the dark, with the microwave light gaffa-taped over (put the bulb in a glass jar first for safety). That's next.
