暑いにをの上に置くと、外側に小さいがつくことがあります。がこぼれていなくても、の上が丸くぬれるので、のやに水が移りやすいです。そこで、の下にを一枚置くがいます。
On a hot day, when you put a cold water bottle on a desk, small drops of water may appear on the outside. Even if the drink has not spilled, the desk can get wet in a round shape, and water can move to a nearby notebook or handout. That is why some people put one handkerchief under the bottle.
でもでも、の上には紙やスマホがあります。を動かしただけで、ぬれた丸いあとが広がることもあります。を下に置けば、その水を吸ってくれますし、置くもなります。のから外へ出たあとや、氷を入れたではが出やすいです。
At school or at work, there are papers and phones on the desk. Just moving the bottle a little can spread the wet circle. A handkerchief underneath absorbs some of the water and also makes the place for the bottle clear. Drops appear more easily after coming from an air-conditioned room or when the bottle has ice inside.
もちろん、がぬれすぎたらで乾かします。大事なのすぐ横には置かないが安心です。にをときは、まず底のまわりを、が出ていたら小さい布を下に入れます。休みのあとも、布だけずらしてをふきます。
Of course, if the handkerchief gets too wet, you dry it somewhere else. It is safer not to put the bottle right next to important documents. When taking out a bottle at a desk, first look around the bottom, and if there are drops, put a small cloth under it. After a break, you move only the cloth a little and wipe the desk.
