I've shaken the bottle, blown very slow to try to get a bubble, and it is too hard to get bubbles. I've just ordered another brand to see if I can find a good product. The actual device for blowing bubbles has a tiny flat handle (not as shown in the picture) and you have to dig down in the bottle to try it fish it out which is messy. I had other brands that worked much better with a double option device to use to blow bubbles. My cats love to run after the bubbles. This was a disappointing purchase.
