What a fun idea, I thought, and immediately wanted to make one of our own with Hunter. I found out that the gravel was necessary and we made a field trip to the pet store.
We decided to make a big one in an empty aquarium we have and put about an inch of gravel in the bottom.
We put about two inches of potting soil on top of the gravel and scattered random flower seeds in there to see which ones will grow. Okay, so maybe not the best way to do it: but of all the seed packets we had, they were all pretty old and I wasn't sure if any of them would grow anyway, so I figured with about five packets of seeds in there perhaps some of them will sprout. I also stuck in there all the little flower sprouts that grew in spite of me in our flower flat we've had for the past few weeks.
Alright, so I'm not the greatest gardener, but I'm learning. Maybe after we learn a few things from this one we will have a real one that we can work to keep up later on. But either way, the point of this terrarium is to demonstrate the way water was distributed when God first created the earth: it circulated through the air and moistened the entire environment. It was never too hot, never too cold, it never rained, and man didn't have to do anything to make the plants grow, because they grew on their own.
"And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. And God called the firmament Heaven. And the evening and the morning were the second day."
