Although the product that I made is not the best it can be, I am glad it works. This toy is supposed to be subjected to kids at younger ages. If I had more time, I would make the randomizer better by having two of them so that if the one of the sticks get stuck, you could use the other to spin the fidget spinner, I would also make the measurements of the teeth more accurate because I accidentally cut the holes to close to each other, causing the cardboard to slightly rip when the popsicle sticks are pressed. Furthermore, I would make the design look aesthetically more pleasing. However, despite all the flaws, my design works overall. By opening the mouth, a pin connected to the mouth pushes a popsicle stick until the screw in the end gets stuck under the rim of the paper cup ring. In this process, the rubber band connecting the popsicle stick and a stable box that supports it is pulled. This allows the mouth to stay open. Then by pressing on a specific tooth, it also pushes down a side of the fidget spinner. The spring connected to the bottom of it allows the other side of the fidget spinner to lift up while the side in which the tooth is on is down. Finally, this makes the rubber band pull the popsicle stick with the screw backwards, making everything reverse and thus, bringing the mouth back down again.
