Don’t eat beef, people.

It would be cool if u could use bamboo shoots but let them keep growing, so that it’s kinda like a living greenhouse.

The bottles are stacked on a bamboo stake like a skewer stick. A hole is cut in the bottom of the bottle, or the bottom section of the bottle is cut off. When you have enough bottles cut and cleaned (labels removed and inside of bottle washed) you place the bamboo stake through the opening on the bottom of the bottle, and up through the neck of the bottle. Then the next bottle is placed on top of the 1st bottle and continue stacking until you have enough bottles to fill your space, then you move on to the next row/space using the same method as before. I hope this helps to answer your questions.

That’s not the whole truth 😉
Germans prefer to drink beer from glas bottles, some water too, but usually plastic bottles (although not so healthy, but not so heavy) with 25 cent deposit, also for cans. Every supermarket has a machine for giving back such bottles and cans and yoghurt glasses too. For paper recycling every house gets a so named “Blaue Tonne” for free. It’s also possible to bring it to a recycling company and get back money. Also a “Gelbe Tonne” [yellow refuse bin for the collection of recyclable packaging material, e.g. yoghurt pots, detergent bottles] we have for free. Did I forget anything? 🙂

Psych- why would one want to? Gee… why do you lack the imagination to understand why a greenhouse of recycled materials holds the interest of people? I’m sorry it’s confusing.
