Black Cobbles

Pebbles & cobbles can be used for an array on different things, to decorate your outdoor setting, be used as a mathematical tool for counting and problem solving or as a mud kitchen ingredient. These beautiful black cobbles change colour depending on whether they are wet or dry. Children can see the different colours by wetting them to make them black and as they dry out watching them turn into a grey/silver colour.
