"Just keep swimming, Just keep swimming." Said Dory in 2003 Finding Nemo. Biologists recently have discovered a baby clownfish, which was no bigger than a grain of rice! can swim hundreds of kilometers within their first week on earth. They start their long journey as soon as they come out of egg.When they leave they can as long as two to three weeks looking for a new home.In a test scientist took a DNA sample of a fish in a reef and they took the DNA of the fish in another reef two weeks later, which the reef was 250 miles away from the first reef. They found two small fish that had the same or similar DNA. That suggests the baby clownfish swam all the way from one reef to another in search of a new home.

the ultimate playground trick of completing a 360-degree swing on a swing set. Three professional stuntmen pushed and pumped in an attempt to accomplish the full swing.But getting enough rotational centripetal force on your own to overcome gravity's downward pull is simply impossible. None of the trio could crest the top of the swing set, much less sail all the way around it.Not even a 65-pound dummy could completely circle around the swing set.Have you ever tried to do this, I have but never could. Ever though it have been proven impossible, do you still try?
