A Bubble Wall is a great way of saving space especially in a sensory room. It is strong and sturdy and only requires 1ltr of water! It has a colour hold feature so you can stop it on a particular colour desired. The lovely colours are visually stimulating and will hold the users attention for ages. Perfect for a multi sensory room, it fits in beautiflly with wall padding. Add a Switch to control the bubbles and a Controller to choose the colours.
