<p>A temperature indicator for taking the temperature of children overcomes the dangers of a glass thermometer by using non toxic temperature sensitive elements which melt or disappear completely at a particular temperature. An indicator comprises a body (12) of confectionery which surrounds a sleeve (27a) made of a flexible material.
