Answer: by squeezing and releasing a bulb attached to the wide end of the pipette.

Explanation: use a rubber pipette bulb or a mechanical pipette filler/pump to draw liquid — never mouth‑pipette (sucking with your mouth) because of ingestion/inhalation hazards. Pouring from a beaker or dripping with an eyedropper are impractical and can cause spills or contamination.
