Pipettes are very useful for dosing liquid medicines or other substances in the laboratory, or sometimes for cooking and baking at home, because they allow you to dose the desired liquid drop by drop. There is usually a squeezable rubber at the end of the pipette, which is used to create a small vacuum to draw up the liquid. The same rubber is then squeezed again to dispense when the pipette is no longer in the liquid. The rubber therefore ensures that the pipette can be both filled and emptied. Squeeze to empty, release to fill. An interesting thought: when I let go, I get something. We usually have a different understanding: we think we have to actively grasp what we don't want to lose. Here it is the other way round. Perhaps this comparison will help you in an area where you need something and yet realise that you are not getting anywhere on your own.
I wish you an extraordinary day!
