Some magic tricks, such as disappearing ink or candles that won't blow out, can be explained by chemistry. In this clip, three classroom chemistry experiments demonstrate that some familiar magic tricks rely on acid-base chemical reactions, and the properties and behaviour of gases. Watch closely if you've ever wanted to ...

Imagine you could walk on water! Some insects can do just that. Watch as the Surfing Scientist uses a paperclip and a glass of water to demonstrate how this is possible.

• TLF-IDM018516

Imagine trying to pick up a slippery ice cube with just a piece of string. Watch the Surfing Scientist team demonstrate how it can be done, using a surprising additive.

This six minute video segment from Catalyst Two compares two beaches, one with white squeaky sand, the other with darker non-squeaky sand and their sand studied under a microscope. Dr Tim Senden attempts to shed some light on this mystery with the use of a visual model. Sand avalanches and the production of sound come into ...

View vineyards of the Yarra Valley region of Victoria in a news clip from 2006 and discover a warming climate's consequences for the region's wine-grape growers. This clip examines some of the ways these growers can adapt to climate change. An environmentalist also gives views on climate change and issues politicians with ...

This six and a half minute video segment from Catalyst explains Earthshine as light from our own Earth reflected back from the Moon's dark side. A PhD student is studying it to learn about how light reflects from a planet that contains liquid water as well as land. Her work may one day lead to the discovery of other planets ...

This 11 minute video segment from Catalyst provides an excellent explanation of the processes involved in recycling sewage for an urban water supply. It also provides a range of opinions and concerns in an excellent debate on the topic.

• TLF-IDM016775

This 9 minute video segment from Catalyst shows how inspiration from the world of animals has helped in the mechanical design of robots and adhesive materials.

• TLF-IDM018844

Graphene is perhaps the most significant new material produced in recent years. It has many potential applications in electrical devices, biomedical technology and solar energy. Graphene is a form (allotrope) of carbon with some special chemical and physical properties. Watch this clip to explore the molecular structure, ...
