Leidenfrost effect Rapidly boiling liquids can hover over surfaces… how?
Levitating magnets See the power within superconductors; future research in action
PP S1.4: proposes ways of reversing a change of state after observing how some materials are changed by heating or cooling eg. ice - water - water vapour.
- explores and describes how pushes and pulls can make things move

PP S2.4: - identifies various forms and sources of energy and devises systems that use energy.

PP S3.4 - identifies and applies processes involved in manipulating, using and changing the form of energy.
