[edit] Suction Cups?

What type of adhesion do suction cups fall under?--DataSurfer 21:37, 2 October 2006 (UTC)

Suction cups don't work (primarily) by adhesion. They are held onto the surface by atmospheric pressure and held in place by friction. —Ben FrantzDale 19:26, 17 January 2007 (UTC)

[edit] Water

There are three pictures of water adhering to different things. How does that work? Is it related to the hydrogen-bond cohesion? Askewchan 10:02, 12 February 2007 (UTC)

[edit] Molecular attraction?

One of the mechanisms listed, mechanical adhesion, isn't attraction on a molecular level -- which is how adhesion is defined in the first paragraph. Are we sure that adhesion ONLY refers to "sticking" that occurs at a molecular level? In which case, it would seem that mechanical adhesion, such as velco wouldn't qualify; and if not, what would you call it when things stick to one another but not at a molecular level?
