Science Explain why you can slightly 'stack' water above the rim of a glass if you pour the water in slowly. Asked by Dr. John Carmen on 18 Jan 08:04 Last updated by anonymous on 20 Jan 00:21
First of all, this has to do with surface tension. That means that the very top layer of a liquid surface has a type of bond running across it, like a sheet. So, if you pour slowly, then the bond remains intact.
