The only thing cooler than soap bubbles are bubbles filled with smoke. If you’re planning on decking your home out for Halloween, we’d like to suggest the Bubble Fogger 200w. As the name implies, all it does is make smoke-filled bubbles, large and small. They’ll leave a little wisp of smoke when they pop, and will give your front yard that cachet that no amount of scarecrows, zombies, or witches could ever provide. Some Amazon reviews suggest that the device suffers from some minor workmanship and leakage issues, but if you’re willing to provide a little elbow grease, it does appear to work as advertised. It’s around $218USD.
