Is gravity real?

1. That's heavy

2. So the white stars are heavier than the blue but the white stripes lighter than the red?

And the blue part is lighter than the red and segregated from it?

Blue textiles tend to be lighter than white and red, but white is heavier than most other textiles, so why doesn't the red float to the top?

3. To cats, gravity is optional.
