Osmosis is the process of equalization of a solute concentration across a semipermeable membrane. Molecules flow through the membrane from a region of high solute concentration to one of low solute concentration. Although this cuff bracelet doesn’t directly demonstrate the process of osmosis, its fluid, irregular holes nevertheless invite you to meditate on this process. For example, biological membranes are semipermeable. Which molecules cross them freely by osmosis? Which don’t and need to be actively transported? These questions and more can be contemplated by gazing into the hypnotizing pattern of this bracelet.
