Sure they do! Finding the right device is a matter of how much you want to spend. There are some high-quality water guns that are inexpensive, but they tend to be few and far between. Do your research and, when all else fails, go with a brand name! Also, go with a company that has a good return policy. A note of warning though, after so many years almost all plastic receptacles will tend to leach out water. Therefore, even with the tightest water seal, eventually, each device will need to tossed and replaced with a new one.
