pickle jar terrarium - wonder how long they last - seems like it would run out of air or nutrients or something, and once you unscrew the jar again, you wreck it - but maybe as a more ephemeral terrarium project. and it's just a pickle jar!
Wine bottles, jugs and carafes can be laid on their sides or even hung with wire. Want a super-easy (and practically free) terrarium project you can complete with the kids? Try using a plastic soda bottle.
