The bottles run out of bubbly liquid in 5 minutes. Makes only small bubbles

I bought this for by daughter’s first birthday party. We had a bunch of kids coming to it so we needed something to keep them engaged while the adults caught up with our stuff. It was really comfortable for the kids to use and they had great fun. But the bottles themselves had very less liquid and the last 1 cm of the liquid was not accessible by the retune. And the bottles lasted only like 5 minutes if you constantly kept blowing bubbles. It kept the kids engaged for around an hour. Luckily we had a lot of balloons which diverted the kids after a while. But overall it is a good party item and we also get refills.
