Pen Cap method

1. This only works with pens with caps!
2. First, take short notes on a small slip of paper. Make sure it will fit inside a pen cap.
3. Roll up and slip the paper in the cap of the pen you are going to use. Put the cap back on the other end of the pen (tip exposed so you can write).
4. Remove the cap and pull out your notes when you need to (this will take some effort). When you are done, re-roll the paper and put it back in the pen cap. Put the cap back on the end of your pen and keep working. Repeat if necessary.
5. If this is done a lot, people might start to get suspicious of cheating. Do it as little as possible and only when absolutely necessary.
6. Using multiple pens will give you more notes.
