So my therapeutic bed blows hot air up through a mass of silicone beads the size of sand grains. If beads leak out they form drifts on the floor, like natural sand would, but some say they can taste the plastic in the air. I seriously doubted this until, like Wegener's contemporaries when he proposed continental drift [now plate tectonics], I thought of a possible mechanism. What happens, I wonder, when the beads collide, like nearly microscopic worlds? Microplastics are produced by decay over time, but there could be other ways. Now I worry every time I take a breath. Dare I look for published research on this topic?
