My wife started talking about plasma cutters last night.

[Haywire]

We were walking around Harbor Freight last night where I was buying some welding gloves and magnetic holders and she started asking me questions about plasma cutters out of the blue. I haven't mentioned them as my lack of need for one so greatly outweighs the cost that even I can't stretch that to seem logical, and that's saying something.

She got to joking about making her car a convertible with one and asked me how they work and what "plasma" was. I told her that it was the same plasma that you donate down at the medical center and you had to keep the tank full for it to work. I really didn't have an answer for her. All I could tell her was that it was electrical energy that melted the metal and compressed air blew it away. She said she's fascinated by them and said it seems all so Star Trek-ish. She wants to see one in operation and try one for herself for some reason.

She's got some project or idea rolling around her brain... Should I try to tease it out or just let it perk for a bit?

What is plasma btw?
