I'm guessing you are talking about Mark Poulton's Bubble organ.. Basically mark bought a theatrical bubble machine (Mains Powered) and built a box around it to resemble an organ. Mark has the luxury of 13 amp sockets in his booth on the beach so doesn't have to worry about battery powered this and that.
you can get battery powered bubble machines from the Early Learning Centre
