The Science of Space Dust

The Science of Space Dust

The eating experience of food in general but sweets and desserts in particular is a combination of taste, smell and mouthfeel. Taste and small when combined are termed flavour, which curiously is much more smell than taste. Mouthfeel is all about texture, and, for example it is surprising how small differences in particle size cause a significant difference in mouthfeel. The creaminess associated with ice cream is caused by a certain particle size of both fat particles and ice crystals. If the ice crystals get too large, the ice cream loses its creamy texture and feels harsh and abrasive.

In this experiment we will demonstrate that a small crystal of Space Dust contains more than its volume of carbon dioxide, this being made possible due to the manufacturing process which causes pressurised carbon dioxide to be trapped within the crystals of space dust.

Experiments you can do at home

Welcome to Dr Hal's Backyard Science, experiments you can try at home. These are experiments that you can try in your garden or house with parental permission and supervision. Each of them comes with some health and safety instructions that an adult must read. The text is reproduced by kind permission of Education in Chemistry a journal of the Royal Society of Chemistry.
