Children can position themselves in different rooms, indoors or outdoors in any play environment and hold discussions with a partner they cannot see! The voice comes through the tubing beautifully and has a real feeling of a ‘telephone sound to it’. Great for garden/playground use and the tubing can be buried underground or in sand for added effect. Handsets can be used alone to help children to hear themselves and can be removed from the tubing for easy cleaning. A fantastic tool to develop language and communication skills as well as encourage social interaction.
