Two very generous friends of ours bought this amazing bubble tube for Niamh as a thank you for letting them stay with us whilst their house move was going through.
Niamh absolutely loved it (as you can see) and despit her being cortically blind, she continually smiled and was stimulated by the colour change of the bubbles and the noise and vibration the tube made.
Niamh's tube came with a colour touch pad, to try and allow her to understand that she could make something happen - by touching the button, the colour changed or the bubbles stopped.
This tube was purchased from a shop called SpaceKraft, which specilaises in sensory equipment for children with special needs. http://www.spacekraft.co.uk
It does have some amazing stuff but if I'm being honest, they are very over-priced. I don't know how companies like this can be allowed to get away with it, but something we found along our journey was that every shop that sold something for "Special needs" also comes with a "Special" price tag!
