Mammoth dark blue 3-foot balloons for longest fly time and distant impact. STICK HINT: 3-foot balloons used as a topper will allow smaller balloons to float longer in hot weather. Blue is a cool neutral and calming color and works well with other colors.
BALLOON FACTS! Larger balloons fly longer. Latex is porous and the helium slowly escapes. So, larger balloons will maintain more helium for a longer period of time. Slightly under inflate to allow for expansion on hot days. Using a larger balloon at the top of a balloon column where smaller balloons are attached underneath will help the entire section fly longer than the smaller balloons by themselves. On hot summer days with high humidity, balloon flight time is reduced, sometimes to almost half the time. Purchase larger balloons if these conditions exist in order to get the longest flight time possible. Do not over inflate balloons. They should appear round and not pear-shaped. The following are average flight times based on size. Actual flying times may vary depending on temperature and atmospheric conditions. 14” – 26 to 30 Hours 16” – 30+ Hours 17″ – 35 to 50 Hours 3 Foot – 3 to 5 Days
