Can I inflate a latex balloon with helium?
Latex balloons can be inflated with air using an electric or hand pump or a little of your own puff! Alternatively, they can be inflated using helium.
Mini balloons (12cm diameter) should only be inflated with a balloon hand pump or your own air.
Please note that the float time for helium-filled latex balloons is approximately 6-8 hours, depending on temperature and other conditions. For this reason, it is recommended to inflate the balloons as close to the time the party begins as possible.
The float time of latex balloons can be significantly increased by using a special high-float mixture. This coats the inside of the balloon creating a barrier slowing down the release of the gas through the balloon. High float can be purchased through balloon specialist shops.
