The force from the collisions on the bottom of the object are greater the ones on the top so the object has a net upward force.

For surface tension, something different is going on. There is an interaction between the molecules in the water and the aluminum and between other water molecules. This attractive force makes the surface of the water kind of like the skin on pudding kind of. For the video above, the effect of the water molecules attracting to the aluminum and to other water molecules exerts an upward force on the disk. Oh, in this case, there is also some buoyancy force - but clearly that is not all that keeps it up.

If you push that disk below the surface, it will sink. Under the water, there is no surface tension. The borderlines of each flow regime were obtained by interpolation and the flow regime map was obtained. This is a preview of subscription content, access via your institution.
