Made an interesting observation in relation to the behaviour of oxygen 'bubbles' in a confined space. For example in a cup of water when stirred and pockets of oxygen or 'bubbles' are created in the liquid by trapping air in the meniscus, the bubbles are drawn, in a manner resembling magnetism, to any solid in the cup. Is this because of water's polar nature or the air pocket's unstability as a molecule? Would appriciate any answer!
@Falco Tinnunculus,
I have often wondered why a handful of Cheerios will clump together in a bowl of milk. I'm guessing surface tension, but I think that comes down to being more a name than an explanation.
