Will My Helium Balloons Last Overnight?
It depends on several factors, such as the size of the balloon, the amount of helium it contains, and the temperature and humidity of the room. Generally, latex balloons filled with helium will start to lose their buoyancy after about 12-24 hours, while foil balloons can last for several days. To increase the chances of your balloons lasting overnight, it is recommended to keep them in a cool and dry place, away from direct sunlight, heat sources, and drafts.
