Optical Illusion and Angular Momentum Challenge

We created a yo-yo and two spinning tops, all with optical illusions on them. The yo-yo functions perfectly, and it creates an impressive optical illusion. The spinning top on the right creates a blue-orange mix, while the left top creates a grey-red illusion in the middle.

We decided to create objects that spun to create angular momentum, and created different optical illusions. The only minor difficulties that occurred were trying to get the top to spin as best as it could, and also we had to separate the two circles in the yo-yo so it could function correctly.

If we had more time we would find better string and cut our circle out of stronger material so it would last longer, and spin more smooth. We would also make the spinning top column out of either plastic or a metal so its more durable and could spin longer.
