DIY Mini Terrarium

I know this isn't that original, I see it all over Pinterest, but I thought it would be fun anyway.

All it takes is:
~a jar ( I used a nice big pickle jar, although I've seen it done in lots of things --even big empty light bulbs.  I also have plans to take the paint off the lid),
~some rocks for drainage at the bottom (I got mine at the dollar store, and now I'm kicking myself because I should've just picked up pretty ones near the river instead of wasting money --especially since you can't see them very well anyway),
~some potting soil (I may have put too much in here, but maybe it will compress over time),
~some moss and other little plants. (I gleaned some from a nearby spring, but I know you can buy it all from the store as well.  Then maybe you won't get little stowaways --So far I've found small slugs, tiny beetles and some almost microscopic snails.  Oh, and a mosquito of all things, but I think he adds to the mesozoic theme we've got going, I'm sure they had giant bugs like that --or maybe I've been watching too much journey to the center of the earth).

Look closely, do you see it?

~a small figurine if you want. (I didn't have any cute woodland creatures, but I did have some dinosaurs, so that's what we put in there for fun.)

 ~Add some water and voila!  It's its own little ecosystem in there.  (Although, I open it up and blow in it every once in a while to give the plants some CO2 just in case).

It makes a nice centerpiece.

The kids think it's pretty cool (although it's hard not to want to get that dinosaur out).  We'll see how long it lasts.
