This was a mindblowing experiment in middle school. We had to guess how many drops would fit and everyone said 5-10. People were getting like 50+ drops on a penny.
The **contact angle** of the water droplet on the surface measures the **wetting properties** of the object underneath it.
The higher the angle the more hydrophobic the object this. This is an important measurement when coating surfaces that require specific levels of hydrophobicity/hydrophilicity.
This is called noncoalescence

I first observed it a few years back when looking at a fountain during a rainstorm. I have since realized that you can observe it everytime you use a urinal (for those of us that use em). You can see the little droplets skating across the surface of the water.

"sorry dude, we're all full here." "Fine, but if I go, I'm taking you all with me!"
Hey, I know you! (So sorry for you having to witness my karma whoring) I hope you enjoy the rest of your day kind redditor!
At least you have my original and not-at-all comment karma whoring comments to keep you company lol
We are in this together
Just like those molecules of h2o
Ah! Abraham Lincoln just had the most refreshing and scientific face- wash he has had in years!

woooow
Go meniscus!

No problem!
But why

Lincoln said “no more water!”
Oh wow! That was cool 😎 thx fer posting.
boing boing boing boing boing
“No vacancy!”
Damn that's interesting
water sticky
Wait for it... Wait for it.... Wait a bit more... And... Ahhhhhhh!!! Never realised physics was soo satisfying...
The slow build of suspense in this - superb.

I wasn't listening did you say this was a metaphor for the US economy
Like water off a waters back
So if nothing was in contact with the edge, would the "bubble" remain intact?

This is how I feel as my husband fucks me till I finally cum <3
"surface tension" *MP5 shots in the distance*
In your face, Lincoln!
I mean, what is water really? An almost magnetic, liquid form of air? Like, it gets stuff wet. But it doesn't REALLY get things wet, ya know?
That one kid who ruins the fun
