Pilot balloons, as opposed to sounding balloons, take a very small payload and are used for measuring wind direction and speed. This one is orange, 20 gram latex and will carry 4.4 oz. Inflates to 15.75" to 17.71" and bursts between 31.5" and 35.4", none of which matters if you're just decorating the yard for a barbeque. (What does matter is that if you're decorating the yard, you should keep this delicate membrane away from sharp branches, rough concrete, canine's canines, and other hazards.)
