This is a tricky question.
Generally the specific gravity of gypsum is greater than water and therefore it won't float.
However, if the gypsum is a little amount of very fine powder, it is possible to sit on the water as its mass will not be great enough to break the surface tension.

Natural occurrence of gypsum is found in rocks. Pure gypsum is white. Impurities can be grey, brown or pink. Its scientific name is calcium sulphate dehydrate or hydrous calcium sulphate. The powder of gypsum is useful. How can we make powder of it? Gypsum powder plant, which is mainly consisting of gypsum crusher, grinding mill, etc, is the production line to manufacturing gypsum powder. 100-1000t/d is the most ideal gypsum plant. In the modern industry, usually, the gypsum powder has 100mesh, 800mesh, 1250mesh, and 4,000 mesh.

Are you planning to build a boat out of a gypsum board? It will float may be for a while but it will eventually sink.
I know for a fact that gypsum are additives on making cement and I didn't noticed anything floating when I mixed cement when doing construction works.

It depends upon the particle size of the gypsum. If you grind the sand into a very fine powder, you can probably get it to float for a brief period. An alternative to dry this would be to take some talcum powder and blow a fine dust on top of a saucer of water and see how long it takes to sink.

What's up with all the gypsum questions on here tonight? This is the second one. Strange.

you should check the volume of water to gypsum if the volum of water is more than gypsum therfore it dropps down
but 80% it will float if it were not they never give u this que.
