So, when to simply put it, when you poke water with a pen, does the surface area increase or decrease? how does the surface area affect the surface tension?

SURFACE AREA INCREASES
IT'S VICE VERSA

They are two types of material
hydrophobic substances such as benzene not soluble in water which repeals molecules of water
Hydrophilic which have charged groups or polar groups such as acids highly soluble in water which attracts molecule of water
Finally there are substance like soaps which have molecules which have a long hydro carbonic chain and a polar group
These substances when put in water change thesurface tension and remove the impurities and are good for cleaning
