It's pretty cool, but most people probably wouldn't know what you were talking about. I had to look it up.

Our voting system is broken! It nearly guarantees that we will have only two political parties that have any chance of winning, and that they will be very similar.

I've heard of this online but have never seen or done or done it myself. Can someone briefly describe how to do it?

it's not very easy... you need nitrous oxide and carbon disulphide.

put as much nitrous oxide in a measuring cylinder as possible, then add a few drops of CS2. cover it and shake it around to disperse the CS2, then drop in a lighted splint.

be very careful that your nitrous oxide is pure... there is a danger of explosion if it is contaminated. wear gloves and eye protection and do it somewhere well ventilated, preferably in a fume hood, since the sulfur formed stinks to high heaven.
