Fractional Distillation of Oil
Starting with Synthetic Crude Oil the students heated the oil progressively heating it to a higher temperature and collecting the fractions. The first fraction burnt but the subsequent ones apart from the last wouldn't burn.

Static Electricity to Direct Current Demo
A good fun experiment taking the static electricity from a Wimshurst machine and passing this to a capacitor plate and using a graphite-covered ping pong ball to transfer the charges which can then be picked up on a beam galvanometer.
