Abstract: Educational/diversionary apparatus is arranged to present a user with various different scents and data thereon in order to aid scent recognition and enable a user to decide upon a combination of scent types which would be desirable to him/her. The apparatus takes the forms of a kit having a number of different scents and data carrying means, such as a CD Rom, which holds data on the nature, geographical origin and/or source of each of the said scents, wherein the data held on the data carrying means includes a map showing a number of geographical regions and cross-referencing means for cross-referencing each region with an associated scent. The selection of a region by the user can thus result in an associated scent being identified and data on that scent being presented to the user. The data on the carrier preferably comprises a computer program having instructions for causing a computer to display an image of the map and to provide means for selecting an area on the map.
