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 '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
