Living plants
They drink, breathe, bloom and set seed, and bees cross them, so a jar's plants are its own.

How a jar goes
- 1.Build it.Gravel for drainage, charcoal to keep it sweet, soil, sand or peat on top.
- 2.Water it.Enough to soak the soil. Not so much it drowns.
- 3.Plant it.Ferns, herbs, succulents, flowers, a bonsai mother tree. Every seed comes up a little different.
- 4.Seal it.Put the lid on, and watch.
From then on, nothing comes in and nothing goes out. The water rises off the soil, fogs the glass and runs back down. The plants breathe in what the bugs breathe out. Fallen leaves feed the springtails, and the springtails feed the soil. You can help it along, or you can just watch it find its balance.
And there's something else in the shed. You'll know it when you find it.
What lives in a jar
All of it is the real game, recorded as it plays.
Little lives
Springtails, bees that build a hive, butterflies, day geckos, and ant colonies that grow into kingdoms.
Ponds
Dig one out and fill it: axolotls, shrimp, fish, lilies and reeds, all living off the same sealed water.
Carnivorous bogs
Wet peat, a bright lamp, and flytraps, sundews and pitcher plants that catch the jar's bugs.
Glowing nights
Turn the lamp down: fireflies, glow moss and glowing mushrooms light the jar up.
A little chaos
When you feel like it: storms, fire, earthquakes, a meteor, a volcano, a black hole. Or Lizardzilla.
