Our most popular show for older children and adults! Witness some truly ‘cool’ and sometimes explosive experiments using an incredibly cold substance – liquid nitrogen. Discover what really happens when liquids boil, learn about frost bite and find out why the Sydney Harbour Bridge shrinks on a cold day. Science concepts include thermal contraction/expansion, boiling points, pressure, temperature, the effects of freezing, cryogenics and changes of state.
