The stretch, strength and rebound of the ElastaBlast creates an exciting new movement experience that can either contain and hold a rowdy group or encourage risk taking from even the most timid. Like a bungee cord covered in soft fleece, its dynamic rebound challenges individual gravity and balance. Group movement can support individual experimentation with trust, caution, risk taking and release. The ElastaBlast is great for creating shapes because the shapes can be plainly seen. Letter, number and geometric shapes are all fun to make. ElastaBlast can bring fun and creativity to your class. It provides a resistance that maximizes simultaneous stretching and strengthening of muscle groups. Suitable for up to 4 participants.
