your mini laboratory in a treehouse

You look like a normal teenager, you're about 12-15 (choose your age, I'm too lazy) so your parents aren't often home and you've been homeschooled, you have a good knowledge of chemistry and physics, and although your hands are fragile, you're quite fast and strong.
Because your parents aren't often home, so you wouldn't get bored, they built you a tree house. They didn't build it themselves, of course, but they hired builders, but that's not the point. You built a stove there so you could live there in both spring and winter, and set up a mini-laboratory there.
Description of the area: You have an average-sized plot of land, a one-story house, well-maintained, a small garden and vegetable garden, and your tree house. You are built in a quiet town, but still waters run deep, and they often sell bad goods there (I condemn), behind your fence begins a dense spruce forest, you often go there to pick berries and mushrooms, sometimes with your mother, and sometimes with your father for fallen trees for firewood, there are neighbors around you, but the distance between your houses and your neighbors is about 10 meters, so no one complains, the trash can is at the end of the street, there is a lot of stuff there, because people throw away slightly broken things that they cannot fix, so you can go there for all sorts of gadgets, you have no friends, although no one stops you from making
You can do whatever you want. Maybe you'll be a scientist? Or maybe you'll just enjoy a quiet life? Or will you justify your own "breaking bad" company, so to speak, or will you create new opportunities for changing the human body, say, a fat-loss bar? It's up to you! Good luck.
