For the bubble machine I needed a fan, a rotating motor, bubble sticks and a container for the soap bubble liquid. To produce more soap bubbles, the motor needs to rotate faster. The bubble sticks need to dip into the soap bubble liquid and then they will pick up the soap liquid to be blown in front of a fan to produce bubbles. To test out this logic, I made the first prototype out of cardboard. This turned out to be helpful for considering measurements for the final prototype. Other than the bubble machine as a whole, I also did trials on the CO<sub>2</sub> sensor in the plants' enclosed environment. Moreover, I tried to experiment with the closeness of the fan to the bubble sticks, for it to be able to blow bubbles. Through the trials, I found that the fan was strong enough to blow the bubbles only in specific areas, with a certain closeness. Therefore, I needed to consider and experiment with the distance and placement of the fan towards the rotating bubble sticks.<gallery mode="packed-hover" widths="260" heights="180"> | For the bubble machine I needed a fan, a rotating motor, bubble sticks and a container for the soap bubble liquid.

Connecting the bubble sticks to the stepper motor was also a challenge, and in the end I used small hoses or plastic tubes to attach the bubble sticks to the stepper motor.<gallery mode="packed-hover" widths="260" heights="180"> | ||
