The first experiment was like a magic show before this I only saw in TV. He placed a board with so many sharps nails on it on his body, adds a brick and hammered it. After the experiment, nothing happens to him, he is ok. He asked for some wrong answers because, everyone can learn from the mistakes, when he was being hammered, large force acting for short time, which force is not transferred completely to the body. He is 70kg and his mass will sand equally to each nails, which means each nails will get only 70 grams. The area of the harmer is small and so we need to transfer to a bigger area the force spreads out. This is the reason why he is not hurt. The next experiment is even more look like magic. Liquid nitrogen with the boiling point as low as 196 degree. Then he try so many experiment with Liquid nitrogen like put the rubber ball or the banana and a few more but all of them after he put in Liquid nitrogen they turn to glass . After all he ask us why this happing? We didn’t know the answer he said because of these is plasma: 4th state of matter. The next experiment my first time seeing this pong ball is being sucked by a blower in 1 place, magnet can produce electricity it was a ball in PVC tube and magnet ball. Professor Doctor Natarajan explain to me physics also can be fun essay to learn and I think I learn physics by doing that and see how it works in real .today also we learn so many thing about physics and so many experiments . I hope I see him
