This unusual gel was highlighted in the Sheffield Hallam Fragrant Freebies project to design and make an air freshener. It melts at just 70°C so can easily and safely be poured into a mould. Colour it when molten by adding wax dye and fragrance it with aromatherapy oils. The correct mixture requires experimentation. If too much oil is added the gel will not set. If not enough oil is added there will be too little scent to permeate the atmosphere. Qty supplied is sufficient for 40 pupils.
