Properties of the Earth's mantle

How do you model the Earth's mantle? How do you explain that it is solid; S-waves (transverse waves) will go through it, and yet subduction can take place into it?
The answer is to try this ELI - 'Bouncing, bending, breaking; modelling the properties of the Earth's mantle with Potty Putty (TM) from a toy shop'.

This is one of many Earthlearningideas about the nature of the Earth: all can be found and downloaded free from our website.
