Submerge your hand in a bucket of water. Some air bubbles appear immediately and others add to the surface of the hand over time. Is there anything that could be added to the water to reduce the creation of air bubbles on the object? (additive/admixture). Alternatively, what could be added to the surface of the object (i.e. hand) to reduce adherence of air bubbles.
I did some searches and came up empty-handed. There is some information about anti-foaming agents (copied below) but did not seem like they would work for this purpose.
Thanks for any suggestions for things to test! Especially if they are commonly available.
(search strings: additive OR admixture to prevent air bubbles formation OR formation water hydrophobic OR hydrophilic -concrete)
There seemed to be a lot of analysis of bubbles in concrete, and about defoamers in paint. But it was not clear whether these would help with my problem.
Here's an excerpt:
Almost every waterborne paint system contains an anti-foaming agent, typically in the concentration range of 0.05-0.5% by weight.
The composition of defoamers is extremely diverse. However, characteristic components of defoamers include the following:
One or more hydrophobic compounds. The hydrophobic component destabilizes the foam dispersion because it displaces the stabilizer. Hydrophobic components are considered among the most active ingredients in defoamers.
Also, hydrophobic components prevent the formation of stable interfacial surfaces between air/liquid. Consequently, the air bubble can penetrate the interface and release itself or it can form a bigger, less stable, air bubble by coalescing with another air bubble. Typical hydrophobic components are mostly solids, such as silicas, polyamides and waxes.
Mineral oil. The mineral oil acts as the carrier for the hydrophobic components. Surface active dispersing agents/emulsifiers. The dispersing agent ensures an optimum distribution of the hydrophobic component in the oil while the emulsifier eases the spreading of the defoamer throughout the medium to defoam. "
