Worm Observatory by World Alive offers a slightly thinner version of the standard worm farm.
Why is this nice? Well the really thick units out there the live worms tend to hide in the middle so you never see them.
Watch worms tunnel, eat, and reproduce in the habitat! Discover the lifecycle of the Earthworm and learn how to care for them. Earthworms are important for the soil. By digging and tunneling below the surface, they help to mix-up the soil layers by moving nutrients and air around. Kit includes: habitat, activity book, sand, soil, magnifier, pipette, and live worm ordering details (worms purchased separately.) Ages 4 and up.
