## Everyday

The pulling force made when air or liquid is removed from a space, so things are pulled in or held on: "A vacuum cleaner works by suction." [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/S/suction/#m1)

### In the lessons

In science lessons, suction is explained by air pressure: when air is taken out, the air outside pushes in. Examples are drinking through a straw, suction cups, and vacuum cleaners. In nature, octopus arms have suckers that grip by suction. Phrases: suction cup, suction pad, by suction.
