Thread: bubble fluid/juice problem

I am having severe problems with bubble fluid, both in a bubble machine and hand held blowers. After a while of usage, the bubbles stop! With the machine, I was making thousands of bubbles.....I left it standing still for an hour (in direct sunlight so not sure if that affected it) and when I turned it on again there was very few bubbles. I have experimented with various different makes of fluid....and the same happens with all of them. I would really appreciate some help on this as I use the bubbles (or try to) as part of my business.
