I’ve come up with a great idea recently. Make a tiny tiny ball that can go through your blood vessels. Then, make a big big ball that you get in and run inside, which controls the motion of the small ball in some good ways. The inside of the big ball is all screen and as you run in the big ball, just like those cute little hamsters in their toy balls, the little ball moves inside of somebody’s body and you get to meet all these blood cells, cholesterol, germs..etc. If you wanna move against the blood flow, you have to run really fast but if you are going along the flow, you can just sit back and enjoy the view.
I think this is one of the greatest ideas I’ve ever come up with and I really don’t understand why nobody’s agreed with me so far.
