Back to the Roots Organic Oyster Mushroom Grow Kit
An organic countertop kit: open the box, mist daily, and harvest oyster mushrooms in about 10 days.

The Back to the Roots Water Garden is a small aquaponic ecosystem: a 3-gallon fish tank with a growing tray on top. Fish waste fertilizes the plants, and the plants help clean the water, per the listing. The kit includes radish and wheatgrass seeds, growing medium, water conditioner, dechlorinator, fish food and a fish coupon, plus a free STEM curriculum. The listing says microgreens can be harvested in about 10 days. It's made in the USA.
It's a living science lesson on a countertop: a betta below, microgreens above, each looking after the other. Kids and adults both get hooked.
