Household liquids with low surface tension?

AI Thread Summary
Household liquids with low surface tension include soap water, alcohol, and olive oil, which are commonly found in kitchens. Sodium silicate, known as "liquid glass," is another option but is not suitable for cooking due to its caustic nature. Caution is advised when handling sodium silicate, as it can be mildly hazardous. The discussion emphasizes the need for liquids with a surface tension in the mid to low 20s mN/m or less. Exploring safe alternatives for household use is essential.

I'm looking for household liquids, preferable kitchen/cooking liquids with a low surface tension. I know of soap water, alcohol, and found olive oil. Any other ideas would be appreciated. I'm looking for something in the mid to low 20's mN/m or less.

Thanks,
-Eric

I had the opportunity to visit a PQ Corporation facility in Utica, Il. recently. They manufacture "liquid glass" --> Sodium Silicate. Sodium Silicate is surfactant ie. lowers surface tension in liquids. Please note Sodium Silicate is NOT a "kitchen/cooking" liquid and is mildly caustic. Exercise care if this is something you're looking for and happen to get your hands on.

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Effect of mass on the acceleration of an elastic pendulum?'

I know that mass does not affect the acceleration in a simple pendulum undergoing SHM, but how does the mass on the spring that makes up the elastic pendulum affect its acceleration? Certainly, there must be a change due to the displacement from equilibrium caused by each differing mass? I am talking about finding the acceleration at a specific time on each trial with different masses and comparing them. How would they compare and why?
