Quote:Bubble machines use a thick glycerin-based soap solution (bubble juice) and a series of plastic wands to generate hundreds of floating soap bubbles. There is no advanced technology behind the bubble production--the wands are mechanically dipped into the soapy solution and bubbles are formed in the open air. A small electric fan may encourage bubbles to move away from the machine, but that's as high tech as it gets.
Bubble machines have been available for decades, primarily as gimmicks for show bands or attention-seeking shop owners. Perhaps the most famous use of bubble machines occurred weekly on the American television program The Lawrence Welk Show. Welk's sophisticated arrangements of popular hit songs was often called 'Champagne music', so Welk used bubble machines to suggest the bubbles found in champagne.
while his music was called "champagne music" , lawrence welk himself was a strict teetotaler ! no champagne on his show :wink:
