Helpful tip from The Garden Geeks: A fun experiment for kids - Let them grow oyster mushrooms! Soak about 20 sheets of newspaper, drain, lay flat, and sprinkle with spawn. Then roll it up tightly, tie and slide it into a plastic bag. Close loosely and store in kitchen cupboard for 3 weeks. Open the bag slightly and place it near a north facing window. Mushrooms should appear in 3 weeks.
