Check out our one and only interactive keychain – the aquamesmerizer! Named appropriately, this cool keychain uses colored liquid to create a lava lamp effect with moving, bright bubbles of color. With several color combinations available, this is one of our most popular keychains with all ages. However, kids especially love it! Outside of the clear casing, the museum logo is printed in white and features the recognizable flying saucer illustration. Everyone will enjoy playing with this one-of-a-kind keychain, so pick one up at the museum or online in our gift shop.
