Points to take note:
- Helium float time is approximately 24 hours, depending on weather condition/temperature and how balloons are being handled and transported
- Foil balloon can be deflated/kept and reused again
- High temperature, long exposure under the sun, sharp objects etc. will cause the balloon to deflate or burst
Adult supervision is required as un-inflated balloons can be a choking hazard. Keep un-inflated balloons out of reach from children and discard broken balloons. Do not inhale helium gas at all time, it can be a health hazard.
