My friend posted a video on Facebook on this product. Although my king isn't at the water balloon fight, the product seems pretty cool. For about $20 you get quite a few balloons. At least enough to hold maybe 3 or 4 fights. I guess the easiest way to explain what it is is: a bunch of straws strapped together each with an empty water balloon at the end. You hook up the top part to the water hose and turn it on. The balloons fill up and seal themselves and drop off (you need a bucket underneath). You can quickly fill up I think it's 25 balloon at one time. Anyone used this?
