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. The apparatus may also be arranged to cause the computer to accept inputs from the user representative of the relative desirabilities of scents in the kit, and means for generating a display representative of said desirabilities.
