Rober is an engineer and inventor from Sunnyvale, California, who’s dedicated his life to science. After receiving a BA and Master’s degrees in engineering, he joined NASA and worked there for 9 years. In his free time, he also worked on his own ideas, and even founded and sold his own company.

While science and engineering have always fascinated Mark, he knows STEM (science, technology, engineering, and mathematics) isn’t as accessible for others. That’s why he also started his own YouTube channel, where he makes pranks, builds machines and explores scientific ideas in fun, approachable ways.

So far, he’s invented a prank to make your friends think you can pull a watermelon whole out of its shell, powered up an electric car with melons, created a glow wall, and invented a glitter trap for package thieves.

Mark’s approach to science is relaxed and fun. He proves that science isn’t just for serious grown-ups in lab coats. In fact, with a little bit of creativity, science can be for everybody.

In the video, we see a bottle containing water being poured out by positioning the bottle upside down suddenly. While the water is being poured out, air tries to come into the container.

The air trying to come into the first container slows down the pace with which the water runs out. The water in the second container, on the other hand, was swirled before it was turned upside down. This swirling pushes the water to the edges of the bottle, thereby creating space at the center that looks like a tornado.

When it is turned upside down, the air coming in goes through the center, while the water flows out around the edges of its opening. Since there’s an air passage and water passage, the water flows without much resistance.
