Posca markers, like many other markers or pens, may not work effectively or at all when you’re flying in a plane due to the change in air pressure and altitude. Here are a few reasons why this might be the case:
- Air Pressure: As a plane ascends to higher altitudes, the cabin pressure decreases. This change in air pressure can affect markers that rely on a consistent flow of ink. It can cause the ink to expand or contract, leading to leakage, drying out, or inconsistent ink flow.
- Drying Out: The low humidity levels in airplane cabins can also contribute to the drying out of markers. The dry air can cause the ink to evaporate quickly, making it difficult for the markers to write or draw smoothly.
- Cabin Environment: Airplane cabins are pressurized and have a controlled environment to ensure passenger comfort and safety. Some markers, including Posca markers, may not function optimally in these controlled environments, particularly if they rely on specific temperature or humidity conditions to perform at their best.
To overcome these issues while traveling by plane, it’s advisable to pack your markers in a sealed plastic bag or container to minimize exposure to dry cabin air. Additionally, you can try carrying markers that are less prone to drying out, such as permanent markers or gel pens, as they may have better performance during the flight.
