Our jetted tub (18 years old) suddenly stopped putting out tiny

ideas?? Thanks, T

There is a big bubble shortage now, because of the increased use of
corn-based ethanol in gasoline. It used to be that a portion of the
corn crop was fermented to make bubbles for hot tubs, jacuzzis,
Lawrence Welk, etc.

But the demand by gasoline companies, cattle and pig growers, and for
corn itself as a food has drive the price too high for bubble vendors.

They are going to plant more acres of corn next season so you can
probably get them then.
