Earlier this year we worked with a student from King James's School to help design a triangular bubble wall as a concept and also build a working prototype.
The product was designed to fit on a table top as a corporate showpiece. It includes the air pump and the lights in a small compartment and was seen as a smaller, more affordable bubble wall.
Various changes were made to the original design (top right) as issues were encountered, such as the removal of one triangle to save space, but the final product looks great. The movement of the air bubbles was interesting, something which we hadn't expected!
