Slippery showers

Why are some showers more slippery than others?

At MyEasyBath.com we understand the science behind the slippery.

Here is what it comes down to:

Soft water reduces the surface tension of the soap, which changes the way the water “wets” your skin, making you feel more “slippery”. It is exactly the same thing that happens when a lubricant comes in contact with something, it changes the way it “wets” the surface, making it also, much more “slippery”.

Here's a lot more information on this and the difference between hard and soft water on skin:

Hard water contains higher-than-ordinary levels of dissolved minerals (strictly speaking, dissolved positive metallic ions) such as magnesium and calcium. Water from underground aquifers – well water, for you civilians – has extended contact with soft calcium and magnesium-bearing rock and mineral deposits such as limestone, chalk, dolomite, and marble, and small amounts of minerals are dissolved into an ionic solution in the water. Often the dissolution process is facilitated by carbon dioxide in the water, which forms a weak carbonic acid. Surface water generally doesn't contain enough calcium and magnesium to be considered hard, although there can be exceptions.
