Water Drops in a Pond

I think the chances would be pretty good - although there would have to be some mixing with the local water.

Easy to check, a bit of dye in the drop and film in slomo!

Use barium and X-rays.

How are you going to use X-rays? Please specify.

This is the best suggestion. Maybe someone has already done it on youtube.

It is like a rubber ball bouncing from a trampoline. The waters surface tension prevents the immediate interaction between the droplet and the static surface. When the initial energy is dissipated then the two will mix because the surfaces will merge together. This is because when the two are in contact for a prolonged time 1 or 2 seconds the suface tension of the droplet will give way as gravity squashes it into the surface of the water. It will burst.

What's "initial energy"?

The kinetic energy the drop has. This becomes incident enrgy as it hits the water.

So what you're saying it's that it is the same droplet bouncing back and then it burst when it hits a second time because most of the kinetic energy has dissipated into the "crown". Makes sense.

This is a really good question to ask . Much better than the hypothetical 'bouncing balls' Challenge question . I shall return when I have had time to think.

Just a guess: Someone smart check me on this guess.

The dropped drop parts the water separating the film. Once the drop passes through the surface film, the created void closes and slams into itself with enough velocity that the only path for the energy is up and as the film was parted by a symmetrical spere (sort-of) the void and resultant closure wave is also symmetrical producing a symmetrical spherical (sort-of) 'up-drop' equal (sort-of) to the mass of the displacement dropped drop from the surface water, not the original drop. ( drop . . drop . . drop >> sort-of sort-of sort-of << >> use as needed to complete or adjust this paragraph)

Can I get some honorary PhD please? Or, is this Seinfeld material ? Think as if dropping a bowling ball.

Might be some clues here.

Great picture, but onto an ultra thin layer. You are going to loose the give of the surface.

Did you backtrack and see the other pics ? All ver good.

Check this out! Doesn't tell us what we want to know, but cool though!

I am talking about that sphere at the top. I've got this picture from the net which shows the bouncing drop.

Hi,

if you use milk on coffee you will see pretty clear that most of the crown is made of coffee without much milk!

But the drops coming up after the mini-droplets of the crown settle, these central drops are first milk and then coffee.

If you let the drop down very gentle without velocity there will some air persist between the drop and the coffee and this will act like an airbearing preventing for some time mixing of the two fluids.

Assuming the droplet liquid is same as pond,the bouncing lqd will depend on the height from which it is dropping.

The % of bouncing volume will change from lqd to lqd, I mean water to water , will be different from milk to milk depends on viscosity and the impact height.

make mistakes.......no blunder

Height is a factor, as explained by BrainWave you need a certain amount of potential energy. Milk is mostly water (SG~1.04). It just looks more spectacular with milk.
