Bernoulli's principle states that as a fluid's velocity increases, pressure decreases. Fast-moving water flowing from the shower head creates a low-pressure area, and the higher-pressure air outside the shower presses the curtain against you in its endeavor for equilibrium. But the leading theory behind the shower-curtain effect comes from UMass Amherst professor David Schmidt. Schmidt won an Ig Nobel Prize for his partial solution of the shower curtain problem. According to Schmidt, the shower's spray drives a vortex - much like a cyclone - that rotates around an axis perpendicular to the shower curtain.
The low-pressure region at the center of this horizontal vortex pulls the shower curtain inward. Schmidt advises that you sew weights in the bottom of your shower curtain liner.
If you have a metal tub, take advantage of the liners with magnets to hold the shower curtain down. And don't be afraid to spend some money on your shower curtain liner. The cheapest liners are often the thinnest and lightest, leaving you susceptible to curtain cling.
Curved shower rods also get the job done. Don't suffer through your showers any longer. What had we overlooked? It might be that water rushing from the showerhead sweeps a stream of air along with it, causing a drop in pressure surrounding the flow. This drop creates a space for air outside the shower to whoosh inward. David Schmidt, a professor of mechanical engineering at the University of Massachusetts at Amherst, decided to test the cold-shower theory. If a shower has enough pressure and a sufficiently flimsy curtain, the air outside pushes the curtain inward toward the vortex.
So, how can you avoid the shower liner and curtain from blowing in on you? While shopping for new bathroom decoration, floor mat, toothbrush holder etc.. We found a nice curtain we liked and then needed to find a liner.
While looking at the liners, I always shopped price. They have different gauge shower curtains.
