The Zero Blaster is available at many stores or from www.ZeroToys.com. I think this makes a nice bubble show addition for a couple of reasons. You're already in a space that's relatively free of drafts, with a dark background and lit from the side. It also gives you another way to play with "smoke". It's fog really. And it's safe too, with in reason. This toy blasts out "smoke" rings. If you don't like the pistol shape, they have another shape that's less so.
