[4] [5] [6] The brightness also depended on the concentration of salt in the water. [4] The switchboard built at Her Majesty's Theatre, London in 1897 had a dimmer scale of 0 to 10, whereas gas lighting only had 3 levels. [1] The salt water need to be refilled regularly, the metal electrodes corroded, and the dimmers emitted a strong smell.
Early examples of a rheostat dimmer include a salt water dimmer, a kind of liquid rheostat; the liquid between a movable and fixed contact provided a variable resistance. The closer the contacts to each other, the more voltage was available for the light.
A liquid rheostat or water rheostat [1] or salt water rheostat is a type of variable resistor. This may be used as a dummy load or as a starting resistor for large slip ring motors. In the simplest form it consists of a tank containing brine or other electrolyte solution, in which electrodes are submerged to create an electrical load .

Add pineapple, margarita mix, and a pinch of chili salt to a cocktail shaker with ice. Shake for about 10 seconds until the shaker is cool to the touch. Strain into glass with ice.
At 20 °C (68 °F) one liter of water can dissolve about 357 grams of salt, a concentration of 26.3 percent by weight (% w/w). At 100 °C (212 °F) (the boiling temperature of pure water), the amount of salt that can be dissolved in one liter of water increases to about 391 grams, a concentration of 28.1% w/w.
Saltwater soap, also called sailors' soap, is a potassium-based soap for use with seawater.Inexpensive common commercial soap will not lather or dissolve in seawater due to high levels of sodium chloride in the water.
