The water dropping is very interesting because the water slowly diminishes in size one bounce at at time. I never thought that water could bounce, but it did. The thing that I do not understand is how the water goes underneath the surface, then pops back up! It was really interesting.
I agree with you Grace C., This was very interesting because I always thought that once the water droplet hits the water it breaks into super small droplets immediately and becomes part of the pool of water. I never knew that it bounced and then got smaller. What doesn't make sense to me is that if it keeps bouncing until it gets smaller and smaller, how does it eventually stop?
I thought it was amazing how the droplet kept forming into smaller droplets. I also saw that when the droplet stopped bouncing, it just laid on the water for a while, and then it split up.
When I watched the video I was a bit confused at first, but then I got what the water was doing. It was kinda creating momentum when is stopped for a it and then bounced back up and became smaller. I thought it was like a babbushka doll when it kept getting smaller. I agree with Finn when he said it kept getting smaller until it is small enough to be completely absorbed.
I thought it was very interesting on how the water breaks apart again so keeps bouncing. I wished they had mentioned how small the drop of water can get. Also I kept wondering when they said "that is what makes insects able to walk on water." Well is their a way that with a big enough drop of water, that it could make us humans or a bigger animal able to walk on water.
Grace C. I believe the water goes under the surface and pops back up is because of the surface tension, and the air is pushing it down and up. Hope that helped you!
I agree with Grace C. because when the water bounced after each time it hit the water it showed me that the density can really move the water and to let bounce it many times. It was very interesting!
That was great. I know I have seen it before, but I am always amazed at how that works. It looks like in most of those it bounced 5 times before finally just going into the water. Imagine what it would be like if we saw it in the ocean with every wave. I also believe that what they said in the video was right. I also agree with Mila about the surface tension. It also said in the video that it acts like an elastic sheet, or something.
I think that is interesting how there is a thin sheet of air between the droplet and the water. I didn't know that is also what helps water bugs walk on water. It's so amazing how the water pops into a smaller droplet. I was a little confused how that worked, but when I realized that when the water drop bounced that it broke into a separate droplet.
I thought that this was cool because you were seeing something that happens so often that you probably weren't aware of. I saw Nick's comment and I thought that the white-wash of the waves acts like that but magnified.
The water bouncing was very interesting but i did not exactly under stand when the man explaining how it bounced. He said that there was a thin layer of air. Since the video was slowed down you could see how the water drop would bounce once of twice and then sat for a few seconds. He also said that when it is small enough that the whole thing disperses. What I don't understand about that is why the drop has to be small to go through the layer of air because the bigger the drop is the heavier it is so it would be easier to penetrate through the layer of air.
This water dropping is awesome. It is so cool how water doesn't just, it gets smaller and smaller until it is small enough to be absorbed by the water. I never knew that it was because there is an air bubble around the droplet. That's what makes it bounce up on the water.
I thought that this video was very interesting. It was a bit hard at first to comprehend how there is a layer of air in between the water drop and the bowl of water. I thought that it was really cool how the water drop bounced up as soon as the air, that was separating the water drop and the bowl, was pushed away letting some of the water drop, go into the bowl of water.
I agree with Miles, this is very cool. I cannot believe that there is a layer of air over water that lets insects walk on it. Also, I could barely believe my eyes when they said that that tiny drop of water become EVEN smaller! It was interesting when the water drop bounced because of the surface tension, it kind of looked like it was jumping on a trampoline. For people that do not know what surface tension is, it is a surface of a liquid that allows it to resist an external force. I wonder if this works with other liquids, like soda. Would the fizz of the soda change anything? In all, I really liked the video. My favorite part was when the drop of water was sitting on top of the beaker full of water.
Wow. It's amazing that you can take something ordinary and make it extraordinary. I think that the whole process happens too fast for the human eye to see, but when you slow it down you can see the whole process. I think it's really cool.
This is what happens. The water drop hits the surface, creating a hole in the air layer between the droplet and the water. This air layer is also what makes the droplet sit on the water for a little while. Then
Um... Sorry. Continuing my comment. Then the surface tension makes the drop bounce back up, but the water has absorbed a little of the drop. This process repeats over and over again until the drop is finally absorbed into the water.
I wonder how the insects walk on the water. if there is a layer of air, do they just walk on the air, or something else? Also, does the height change any thing about this, like how many times it bounces?
Overall, I agree with Savannah. This video is extraordinary.
Its super interesting that when the water drops, then some of it bounces back up and gets separated. Then a thin layer of air is in between a now smaller drop of water and the pond or lake or bath. This taught me why water bugs can stay on the surface of the water and it is from the thin air layer! that was a really interesting thing that I learned rom this awesome video, but I am a bit confused. Where does the air layer come from?
It is really interesting to think about this. It happens every day, but we never go into much thought about it. One thing that was interesting to me was how the droplet stayed on the surface of the water. You don't ever really think about it like this when you think of a water droplet.
I really enjoyed watching this video. I am really interested with this concept. I never knew that water kept getting smaller and then finally sinks in. I always thought that it would just fade away within the water. I thought I was extremely cool when the water literally bounces up out of the water again and then because of the thin layer of air, it pops and gets smaller in size. All in all, I really liked this video. I thought it was really interesting.
This idea was amazing and I understood most of it but water weighs more than air so why would a layer of air be under it. Couldn't it pierce through the air? It was very cool how the force pushes the drop up and it bounces. This was definitely amazing and I thought it just plopped on the water.
I agree with Grace that the way that the water pops back up is very interesting. The drops hit the water that bounce, which was very interesting to see.
I find it really cool that water drops pop back up after dropping at about half the size, sit on the surface of water, then burst and repeat the process! I wonder why that happens.

Hey Annie it stops when the droplet is small enough to be completly absorbed. I agree with Grace that is was really COOL!

Sorry i meant to say tention not density.
It was very cool because water keeps bouncing up and down until it get tiny, and then get absorbed by the pom, lake, ocean etc.
I meant to say pond.
