The museum has its origins in 1923, when the "Museum van  den Arbeid" () was opened by the artist Herman Heijenbrock on the Rozengracht in Amsterdam. In 1954 the name was changed to the Nint or "Nederlands Instituut voor Nijverheid en Techniek" (), and in 1997 it changed again to "newMetropolis". The name "Science Center Nemo" was introduced in 2000. In 2016, the name was changed to "NEMO Science Museum". Exhibitions. Inside the lobby there is a small cafeteria and a gift shop which sells small scale copies of some of the attractions at Nemo like the giant domino set and the DNA experiments. The main concepts on the first floor are DNA  and chain reactions which include a room with giant dominoes with contraptions like a giant bell and a flying car. Also on the first floor is a show on the half-hour, which features a large chain reaction circuit. On the second floor is a ball factory where small plastic balls are sent on a circuit where participants are to group them in weight, size, and color and then send them to a packing facility where the balls go into a small metal box. There are five stations at which the people stick magnetic barcodes on the boxes and send  them off to start the circuit again. On the second level, there is also a small cafeteria and a movie and performance hall where various acts and movies about science are shown. The second floor also features a display on the water cycle a display on electricity and a display on metals and buildings. The third floor has a giant science lab in which people can do science experiments such as testing vitamin C in certain substances and looking at DNA. There is also a small section on money and business. On the fourth floor is a section about the  human mind, it has such experiments as memory tests, mind problems, and sense testers. The fourth floor is quite dark which adds to the eeriness of the surroundings. The fifth floor or upper deck has a cafeteria, a children's play area and a great view of the city surroundings.
