Why does water hold up between the teeth of my comb?

Image for reference:

As can be seen in the above image, whenever my comb comes in contact with water, a little of it is trapped between the teeth. This happens whether I dip it in still water or place it under running water.

1. Can someone explain what's holding up the water? I think surface tension or capillary action may have something to do with it but not sure how exactly they play out here.
2. Would the water hold up even if the teeth were completely frictionless? Intuitively answer seems to be no.
3. Could there be any applications of this phenomenon? I'm seeing that water could be stored at an elevation without continuous supply of any more energy.
• You can already store water at an elevation without consuming energy - that's what tanks are for. Oct 11 '18 at 8:47
• Tausif Hossain used the word, "hydrophilic." Water sticks to hydrophilic surfaces. The opposite is "hydrophobic" (afraid of water). If the comb was made of or coated with a hydrophobic substance, you could hold it under water, but as soon as you pulled it out, it would be completely dry--the water would just slide right off.

I should point out that it is not mechanical friction rather it is intermolecular attractive forces between water molecules and with the molecules in the comb that is making a significant contribution because friction depends on the normal reaction force, $$R$$ by $$F=\mu R$$ and for a vertical water column here friction is almost non-existent as the water pressure is so low at such small heights so the horizontal normal reaction force would also be very low making friction very low as well.
