In the hot summer months an 11″ balloon can float from 3 – 4 days, while in the winter months that same balloon can float from 2 – 3 weeks. 18″ foil balloons can float anywhere from a few days to several weeks, depending on how well the valve is sealed. Smaller balloons such as 9″ latex only have a float life around 6 hours total, while larger balloons such as the 3′ can float for as long as a day or two without chemical treatment. However, just because a balloon can float for 12 to 16 hours doesn’t mean you will like the way it looks within that time frame. As a balloon loses helium, it shrinks in size, becoming less attractive in the process. This is why we li
