I don't understand the question. When you said "sold", I assume you meant "solid", but solids don't have surface tension. Surface tension is the tendency of a fluid to try to maintain the minimum possible surface area. It does this because each molecule of the fluid is attracted to every other molecule by hydrogen bonds. Molecules of solids are often connected in crystal lattices, or in more complicated structures of very large intertwined molecules. Crystal lattices usually can't deform at all, and if the solid is made of long hydrocarbon molecules, the distance between molecules will be smaller than the length of a single molecule, so there will be a lot of mechanical interference with hydrogen bonding. So, solids don't have a tendency to fill a minimal volume. Since they don't have this tendency, they don't have surface tension. Since they don't have ANY surface tension at all, they don't have more surface tension than fluids do. Now, if you're asking "why can solids support more weight than fluids can", the answer once again comes back to the natures of the substances. Solids are held together by stronger bonds than fluids are, so the resist deformation more strongly.

A lot of 'science' is just theoretical nonsense designed for calculations, etc. Most of it has no bearing on our actual reality, I'm sorry to say.
