Can a light bulb also make a micro bonsai? Let me teach you how to make one
I snagged a bit of sand from the construction site downstairs, washed it several times, removed the mud, gave the basin a shake, and simply separated the coarse and fine sand. I dug up some moss from the rooftop (bottom right).

The bulb is a small one, about 6 or 7 cm in diameter, tiny, taken from a broken bedside lamp.
First I put in some crushed stone. I'd read in a post before that this way lets water stay at the bottom and won't leave the soil soaking all the time, otherwise the soil easily gets moldy and smelly.
Then I slowly filled in sand using a funnel made from rolled paper. Coarse at the bottom, then a layer of fine, though it's actually really hard to do, and I feel like it ended up all mixed together haha.
Forgot to mention. The front tip of the bulb, I used the sharp point of tweezers to slowly dig it out, and then there's still a layer of glass inside. At this point you need to pad the bulb with a towel, then hold it and forcefully poke through with the tweezers, and the core inside shatters, then slowly clean out the glass shards inside.
Next is putting the moss in. Slowly break it into small pieces that can fit inside. You need large pieces, then adjust them inside with tweezers and piece them together. The moss came with a bit of soil, so I didn't add another layer of soil. It's really hard to stuff in. I was so focused on doing it that I forgot to take photos.
That's about it. I don't know what that grass is, I just dug it up along with the moss on the rooftop. Just plant it in casually.
Actually, tweezers are great for sending things in. For adjusting things inside, I used a bent stiff wire.
After using the wire, I bent it a bit and made it into a stand
Then……
There is no then. Photo time
Later, at night, I thought, should I give it some light so the moss can survive more easily.
So I found a lamp and found a cord.
After finishing, I suddenly felt this looks quite beautiful too
Later, the grass grew……
