I purchased these bubbles to create the foam for my daughter's birthday party. We used about one bottle per baby pool, but the bubbles lasted throughout the entire party, so I guess that is good. On the other hand, when I tried the bubble bath in the regular tub with my daughter it took far more solution to keep the bubbles alive. With Johnson and Johnson, we only use about two capfuls for our garden tub. We had to use about twice as much of this solution...but it is a lot cheaper, so pick your battle. The shipping was extremely fast! And the bubbles themselves smell great!
