Respiring Reflections
This project is called "Respiring Reflections", a bubble machine which is connected with Pothos plants in an enclosed environment. Read below to follow the process and story behind the making of this project.

First Experiments
In the beginning of our semester, we were given some seeds to be grown at home. This was our first experiments for this class. I was growing Chia seeds (and also apple seeds that didn't really grow into anything) on a piece of cotton and inside a plastic bag. I have not done this since school time, so it was interesting and fun. During our first experiments in growing seeds, we documented our plants' progress. I documented it in form of pictures and diary entries.

Motivation
After attending a few sessions of this class, I started brainstorming what could my topic of interest be. Honestly it was a bit confusing and challenging to try combining/connecting plants and electronics somehow. Before this bubble machine idea came up, I had some more ideas and sketched them in my notebook. In the end, I was interested in the respiration process of my plants and decided to make a bubble machine which can visualize the respiration process/cycle of my plants. I think bubbles are fun and matches the concept of respiration, since they are somewhat transparent/translucent, and we cannot really observe the plants' respiration. With the bubbles, I was trying to simulate or reflect the respiration, hence the project name "Respiring Reflections".
//TODO: add initial sketches
Before the bubble machine idea, I already decided to grow Pothos plants from cuttlings and documented their growth. During the process, that was where I started to think: "Are my plants breathing? They seem fine, their leaves are green... but are they really okay?" The idea was that the soap bubbles quantity would be according to the CO2 level of the plants' enclosed environment, divided into three categories: Low, Medium and High CO2 level. When the CO2 level in the plants' environment rises, then there will be more soap bubbles. In order to do so, I watched videos and read blogs/forums related to the DIY bubble maker machine, until I had a plan on the materials needed and how to make it.
