Spark Pen
Recently our chemistry teacher said that if we wanted to bring in a lighter we could rather than having to wait for the matches. Never wanting to just follow the crowd I remembered a little project I had made a while back.
It was a little thing made with a film canister which you sprayed a little aerosol stuff into and then it had a couple of wires stuck into the canister which I then sparked by attaching them to part of an electronic cigarette lighter.
I took out the part from the lighter and stuck it into a pen and taped it up securely. It makes a nice spark across the gap and a benefit it has over a conventional lighter is that you can give people a small electric shock which is fun. here is a picture and a video of the thing.

The video isn’t that great. I had to do it in the dark so the spark shows up clearly and it is hard to hold the pen still because you are pushing down to get it to spark. Also the camera missed a few sparks because the frame rate was too slow.
