Physics

My original idea for how to do the spin art is to get a drill, canvas, paint, and box. I will cut a hole through the box and place the canvas inside. Next, I will put the top of the drill through the hole and tape the drill to the canvas. Lastly, I will put globs of paint in a symmetrical pattern on the canvas and close the box. To finish the spin art, I will simply hold it up and press the button on the drill. The box will prevent paint from slinging everywhere. I had many attempts to successfully make the drill idea work. The biggest issue was attaching the canvas to the drill itself. The first idea was taping it together but the tape would not stick to the canvas. The next idea was hot gluing it on but the glue would not stick to the drill. The final plan is much more engineered than originally planned. I give credit to Annabelle for creating a wooden beam that is screwed into the canvas, out of the center of the beam there is a bolt that attaches to the drill. 

My plan for the fidget spinner was to layer pieces of cardboard together and attach a ball bearing in the middle. Also, I wanted to peel up the card board to reveal the textured ridges underneath. The prototype was too large and when you spun it it hit your hand. Another issue was the bearing wouldn't spin. To solve these problems I trimmed the size down and replaced the bearing with a more simple support through the center of the bearing to spin it on.
