Wow! That is so cool! I had no idea that there was a layer of air between the droplet and the water below. I can't believe that this happens aver single time it rains. It's crazy!! So that means that Friday, Saturday, Sunday, and slightly today, this was happening!

Amanda said...

I thought that this article was very interesting. I didn't think about or know that the water droplet bounces, because when it rains, I thought it was other raindrops bouncing around. I also had no idea that there is a thin layer of air between the water and air either. This is really cool.

I was aware that droplets bounce off water, but I did not know how this actually occurs. I found it captivating that there is a thin air layer between the water and the droplet, and as the air is pushed aside most of the droplet connects with the water below. It is fascinating when one begins to understand the science behind nature.

Robert said...

Wow! That was so cool! Before I thought just like that guy in the video. He thought that if you put a small drop of water in a glass of water, that nothing would happen. But now I see how awesome that is. So basically when a miniscule droplet of water falls on top of a puddle or a small area of water, the water bubble has a thin layer of air between itself and the water below it. That makes the droplet of water bounce up very quickly and fall back down, then continue to jump upward until it is completely absorbed. The mathematician said that it happens about a billion times a day. So I bet if rain didn't come from precipitation of the Ocean and that it just came from nowhere then the whole Earth would be covered in water!

I think that we saw a video similar to this in room 3, 4 or 5, I can't remember. I already knew about this and how the water drops bounce and then break up. But I didn't know about the thin layer that was in between the water drop and the water. I wonder what it would be like with the rain hitting the ground. I guess it would just spread out into more water drops, and those would spit up then they would stop when they become too small. Thats just my guess...

Emory said...

The video clip was very cool. Just by watching this video, you see another dimension of water falling. Water falling is just a thing we see everyday, but we would have never thought that is was so cool. The thin layer of air must be super thin. The thin air is kind of like a parachute throwing a ball. Things like these amazes me.

Sofia said...

Just asking, didn't we see something like this already in Room 5? The droplet just stays on the top of the water. It is so cool!

Chloe said...

This is so cool! I never knew that there is a thin layer of air in between the droplets for a couple seconds. After it will go into the other water. Than`it forms another thin layer. It does this till all of the droplet is in the other water. When it rains, it must do this a billion times.

Luca said...

This is such an awesome video. It is amazing how the droplets hop up all the time.

Cami said...

I think this article was really interesting. It was so cool how the droplet of water bounced on top of the whole thing of water. It was really pretty, and the ripples it made looked really cool also. Also like Chloe said, it would look so cool to put that camera on when it was raining.

Alex G.. said...

I thought this was really cool. I liked seeing the droplets of water hop on the surface. It is awesome they are able to slow it down so much so we can see the process.

Cypress said...

This is really cool! I never would have thought water would do this. I wonder if it does this on solid ground also, or if it is only when it is on water. I always thought that water just landed and that was it. I thought it was so cool that there is a thin layer of air between water and air. I really enjoyed this video.

Will said...

That is a very cool high-speed video. When the surface tension broke i liked how it only let some of the water into the main body. Also I never knew that water bounces on surface tension of other water, I always thought the tension broke immediately.

Nate said...

That was amazing! This proves that surface tension is a very strong law of nature. It is amazing to believe that it is the principle that controls how water droplets stay together and can make the water droplet bounce on the water. I think it is weird that we cannot see the water droplet bounce even the slightest bit. I never knew that there was a layer of air that was trapped between the water droplet and the water. It sort of reminds me of the Magic Sand, even though the principle is entirely different.

Aaorn said...

I remember that in room four or three Ms. Maulin ( I think that I spelled it wrong) showed us this video. I forgot about it, but it really is amazing.

Edie said...

This video was so awesome! I remember learning briefly about this in Room 5 last year. Also my mom has shown me this video before. It's so cool how they got it to 2,000 frames per second! I was wondering if someone just said, "Oh, let's video this droplet of water and see what happens!", or was someone just thinking about it and they had a few different possibilities in mind, and then they tried it out and said, "Oh, we WERE right!", or they hadn't ever thought about the fact that maybe it bounced on the water, and they, of course, didn't say that.

Anthony the Gamer said...

This video clip was so interesting. I knew that water bounces off the water, but I forgot about it. It was amazing that it just kept bouncing and turning into smaller drops. It's amazing that this sort of thing happens every time it rains or when you shower. This article was so interesting and I will look differently at water.

Sergio said...

Wow. That was amazing though if air layers the droplets wouldn't it happen at a microscopic layer since oxygen is one of the elements in waters.

Esther said...

I remember we watched this video last year, but watching it again, I felt like I understood more things about this concept. I think that it's so cool how there is the layer of air between the water drop and other bodies of water. It also looked really cool slowed down that much.

Kevin said...

I had known that something happened when a droplet hits water, as I'm pretty sure I've seen a video like this somewhere before. However, this was out of my expectations. I'm definitely going to research water's qualities more.

Ryan said...

I think this is really cool. I had no idea that the drop bounces when it rains. I think this is very interesting, and now every time it rains I will think of this video.

Jameson said...

This video is pretty amazing. Just think about it, when it rains this happens all around you. It almost tempts me to film a video of it raining and play it in slow-motion.

Caroline said...

I think we saw this video in room 5! It is so cool how the droplet bounces like a plastic ball. Every time you see a drop of water drop you can know that it bounced, you just can't see it. It is interesting how the thing layer of air is pushed aside and a smaller droplet is pushed into the air. I wonder what you would see if someone played a video of it raining in slow motion. It would be like a bunch of little rain droplets bouncing up and down and being absorbed by puddles. The things that water can do are so amazing.

Emma said...

I thought that this video was very interesting. Water dropping is such a normal and quick thing that happens a lot, but mostly passes unnoticed. You wouldn't think that there is much more to it than water dropping. So much happens so quickly that you don't even realize it. I didn't know that the drop of water gets smaller and starts bouncing every time. If this video was shown at 2000 frames per second, just think of how fast it all really happens.

David said...

Sometimes the most interesting things in science are ordinary things that turn out not to be so ordinary when you study it up close! It’s so fascinating to observe a drop of water in ultra-ultra-slow motion. So many things are happening when the drop bounces and gets smaller and smaller, including the finite amount of time it takes for the air layer to drain. The elastic surface of the water allows certain insects, like the water strider and the water strider, to walk on water without sinking. This helps the insects to escape from predators or to chase after prey. This advantage helps them to survive.

David said...

Sorry, I meant to write the water spider and the water strider.

Jordan said...

I thought this article was very interesting because you realize that this happens every time somone drops a drop of water. It is interesting how there is a thin layer of air between the droplet and the water which allows it to float.

Nick said...

And to think that happens every day right under our noses.

Rehaan said...

This was a truly amazing sight. I never knew that water droplets would become smaller on every bounce, before I thought that water droplets would completely dissolve at contact to the water. Surface tension is a very strong law of nature just like Nate mentioned.

Cooper said...

Water's surface might also have a trace of the same thing that they use in that blue sand too.
