This is a bubble machine by Wilton, it is something we used in a lot of wedding's through our flower shop. We did rent it a lot and I really liked the idea and concept of it, but it has a lot of room for improvements.
For instance, we had one wedding that was set by a huge water fountain, and this machine worked out perfect there. In most outdoor ceremonies it worked out great, but indoor ceremonies it did not unless it was used only during the receptions.
Let me explain, this machine is incredibly noisy! It is ran by 2 C batteries, and you will get about 5 hours run time on a set, but you will need to keep an eye on the bubble fluids, which you have to buy specific bubbles by Wilton for it to work right.
It requires a lot of supervision, I think if it were electric it could be much quieter, also if the reservoir were bigger that would be a bonus as well. But then again, for only $14.99, I knew not to expect much more.
You can buy these on line at Wilton's website, or at Michaels, where I got mine.
