Soap film on a pyramid frame. Soap bubbles form sheets of minimum surface area when stretched between two points. Therefore,when stretched between straight metal wires they will form flat planes. The iridescent bands are caused by reflected light interfering with itself. The differing colours are due to gradients of thickness in the film,caused by gravity | |
