Dark Matter

The Particle Zoo


Is DARK MATTER the key to understanding what the universe is really made of and if it will expand forever, remain static, or eventually contract? Or is it just a piece of black Swiss cheese?

Dark Matter is also part of the Theoreticals 3-Pack and Darkness & Light 2-Pack. No two are exactly the same. This is the heaviest particle in the Zoo.

Approximately 17 oz (481 gm); 5.5 inches (15 cm) across.
For ages 5 and up as it contains glued-on/small parts.
