It's a bit less of a party trick given the inherent combustibility of these other materials, but if we can think of a substance with low ignition energy requirements that isn't commonly viewed as combustible we might have a useful party trick!

Perhaps you could use it to set off a mini explosion with sugar as the explosive agent?
The oil sprayed out when you squeeze an orange peel is combustible- maybe something could be MacGyver-ed from a lemon rind?
