This Jellyfish Tank that carries the Smithsonian name delighted testers who found it to be fascinating, soothing, and educational. It is ideal for the suggested age group of 10+, but parents felt that it could be enjoyed by even younger children (with parent supervision) since it provides a unique experience not found in many other toy/activity sets. It is easy to set up, and the directions are crystal clear. It makes for a great family project and adds to the sense of pride and satisfaction for everyone once it was completed. Like a fish tank, this is something that kids can go back to over and over to watch the jellyfish as they float around the tank. It is quite relaxing and can double as a nightlight. Testers gave high marks for durability, noting that it felt like it would last a long time. There is an educational component as well because it can spark conversation about a specific species as well as other ocean/marine life. Parents felt that this would also be a great addition to any classroom or even for senior citizens. The tank itself is aesthetically pleasing, neutral, and modern in color, and looks great in any room.
