Points to take note:
- Air filled only (due to balloon size/volume, helium inflation does not allow the balloon to float)
- 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 times, it can be a health hazard.
