The effect you're demonstrating is not the decrease of surface tension from 0.07 N/m to 0.02 N/m. This does happen, but it's not the relevant bit. The soap also is a wetting agent. That is what causes the pin to sink.

@grieske

What's the difference? Doesn't a wetting agent mean something that reduces cohesion of water molecules (surface tension)

[grieske]

@flegolas A wetting agent decreases the energy per unit surface of the solid-liquid interface. A surfactant decreases the energy per unit surface of the liquid-vapor interface. Many surfactants are also wetting agents on many surfaces, but this doesn't have to be the case.

Interesting, thank you for this video clip.

...go down the drain. But when you wash your car with soap and water, it causes surfactants to enter rivers which is very harmful to aquatic wildlife.

if u care so much about wildlife stop using soap cause thats a surfactant

What kind of religious organization kills pets?

Former CoS agent Steve Fishman confirms that CoS attorney Ken Moxon ordered OSA agents Lenny Leibowitz and Clarice Guidice to drown a dog. Through a coordinated effort, Lenny and Clarice managed to arrive at Judge Ronald Swearinger's (Scientology vs Wollersheim) house. Lenny threw the Collie "Duke" into the pool and "sat on the dog" until the dog drowned.

Just one of many examples of Scientology killings pets to intimidate.

That's what's so good about the waterless carwash product, Miracle Drywash. No surfactants.
