It’s due to the cohesive and adhesive properties of water. The hydrogen end of water molecules are strongly magnetically attracted to the oxygen ends of other water molecules.
The water has surface tension. The force of gravity being exerted on the water isn’t strong enough to make it spill out over the edge yet. This is also how water bugs can walk across the surface of lakes, and why when you hold a glass of water at eye-level, the water seems to “climb” the sides of the glass ever so slightly. Water is sticky. The smaller the water droplet, the harder it is to break the surface tension. Alcohol by contrast makes much smaller droplets than water even. This is also why old film-makers used alcohol to simulate a larger amount of water in miniaturized water-catastrophe scenes. I know just enough to be dangerous.
I remember the surface tension lesson in science class-”Guess how many drops of water will fit on the top of a penny!” All of us 7-drop guessers were way off…
It’s called Surface tension ;)

Science is so beautiful. :)

i think its a trick.
I think the coin has water on it, basic h2o, that won’t run off.
IT’S A TARP!
Where is the coin from?? that’s my question.
The coin is a Japanese 100 Yen.

I think this is a resin pendant dome I don’t think it’s water at all…
Only 3 words in your reply are correct.
Is it bad that it took me two days to understand the joke in your comment?
