You absolutely should not do this on the plane if you do not want to meet

The fact that you pump too much of a sleepy pillow on an airplane may cause you trouble!

In long flights, it is not too strange for you to bring with you a pillow to sleep with.

Some people choose a cotton pillow with foam, but because the compactness can be folded away at any time, many people choose to sleep with a pillow. However, if you use a steam pillow on an airplane, you must remember this.

That is not to pump the pillow too tight .

Do not pump the pillow too much, as they may be "slow explosive bombs".

Why? Simply because they can break "boom" when the plane flies high.

We know that atmospheric pressure varies depending on the altitude.

When the plane flies high, atmospheric pressure quickly drops. At first, air pressure will balance with atmospheric pressure.

However, if you try to pump the pillow too tight without leaving a bit, high up, the pressure in the cabin changes, it may be pressing on the pillow causing the air in the pillow to expand, if too tight break "boom".

Therefore, you should not pump too much of your steam pillow but let it be a little bit small, so that the air expansion also has a storage area, to prevent the pillow from breaking when the plane flies high.
