How it looks

The Eco-column is made out of coke bottles. There are three zones in our Eco-column, each zone will be in a different coke bottle. At the top of our Eco-column is our first zone, the Terra zone which needs to be watered every day, it has a whole at the bottom of the bottle fulled with stones to lets water but not soil pass out the Terra zone.

Beneath the Terra zone is the middle zone, the Decomposition zone where the water from the Terra zone escapes to. There are smaller wholes at the bottom of the bottle to let the water leave from the Decomposition zone.

Then at the base of our Eco-column is the Aquatic zone where the water from the Terra zone finally reaches it's destination, there is a pipe connected to the bottle to make sure that the water does not overflow from the zone.
