Gelwax
This short film from the Technology Enhancement Programme (TEP) is one of a series of clips which were produced to demonstrate the properties and use of a range of smart materials.
This unusual gel may be combined with fragrance compounds, such as aromatherapy oils, to produce air fresheners. However, some experimentation is necessary to determine the right proportions. If too much oil is added the gel will not set, and if not enough oil is added there will be too little scent to permeate the atmosphere. The gel melts at 70°C and can be safely poured into a mould. Wax dye can be used to add colour while it is molten.
