The Physics of a Cat Lapping up Liquid - Part 1

This movie shows three lapping events of an adult domestic cat, Felis catus, during its normal drinking process. Tap water was mixed with a small amount of liquid yogurt to aid visualization. The video was recorded at 120 frames/s and is here shown slowed down four times. As the tip of the tongue comes in contact with the liquid surface, water adheres to the dorsal side of the tongue's tip. A liquid column forms when the tongue is rapidly lifted. The liquid column grows by inertia, until gravity induces its break-up through pinch-off. Jaw closure results in the capture and ingestion of part of this column.

@TheBinkyp Evertything that moves in the fourth dimension uses laws of physics I agree, but when you stated in the description the physics of a cat… I assumed you would provide some basic knowledge about the physical properties taking place or talking about how when the cat draws its tongue back into its mouth, water is pulled upward because of energy transfers. The water is pulled upward in a column shape between the water bowl and the cats tongue.

@quantummandavid did you read the description?

Cool!

wtf that is not science it is just a video

[meowHAH]

Those smart kitties!
