A hot iron nail is dropped into a bucket of water. The nail cools down and steam rises from the bucket. This is an example of Latent heat. It is also an example of Heat flowing from a hot object to a cold Object. It is an example of Latent heat because when the hot nail hits the water the water releases the hidden particles in the nail and it cools down. And the other example is because while it sits in the water it cools down but also heats up the water a little.

the most interesting thing i learned from the video is that it took 13 years to make the video because as they went on they found new kinds of fish. It took them all that time because they actually went around the world and looked all over. I found out that the fish will hide in crates, or rope or anything they can find so they can stay away from bigger fish that will harm them. They will find anything to hide in to stay away from anything they will eat them. I found out that one kind of fish will go up to the surface of the water and have a bird peck off the stuff off of them, or have fish do it.
