Yes, in particular the non-stick forever chemicals known as PFAS (aka Teflon and its precursors). The same chemistry that makes these plastics so non-stick also makes them resilient to being broken down chemically in our bodies. And the more the government tries to regulate them away, the more the industry plays whack-a-mole with modifications to the formula. It’s the designer drug problem writ large!
The harder thing to convey is the full dimensionality of it. With the rubber sheet (or trampoline) you can show a small ball orbiting around a larger one but only in a single plane (around the “equator” of the large ball). However in reality you can orbit in any direction you like and many satellites actually orbit over the poles. Trying to show that with a small model seems extremely difficult!
Furthermore, most children are raised on the idea that gravity is pulling them down. They intuitively understand the idea that when they climb a ladder and drop a ball from the top, the earth pulls the ball down. General relativity tells us that this is not happening at all! That there us nothing pulling us down whatsoever. I have yet to see anyone provide a lay person GR explanation for the ladder problem.
