A British holidaymaker tells me she needed hospital treatment after a roll on deodorant exploded following a long haul flight.
The ball flew out and hit her in the eye. She was also affected by the accompanying chemical spray. The woman had crossed the Atlantic and had just arrived in a high ski resort.
I have not heard of such a thing happening before. However, though sealed items can be affected by pressure imbalance at altitude, and the incident suggests caution when opening them is prudent.
