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.

Pressure inside a ballooon
Is the pressure inside an inflated balloon greater than that in a deflated balloon? The debate raged on until with a @Pascoscientific wireless pressure sensor proved that the pressure was indeed 1.1 KPa higher in the inflated balloon - the elasticity of the balloon to blame.

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.
