Water is a liquid. and in all liquids there is space between molicules just like gas but lesser than gas. when u drop a solid, for example sugar, its molicules part to fill up that space because there is vaccume and no gas. they dont actually part, they are pulled apart by the vaccume. you must be wondering why it doesnt pull the water molicules and why only the sugar ones; thats because at room temperature, water is stable in liquid state and the vaccume is not powerfull enough to pull the water molicules. solids have lesser kinetic energy (energy to move) than liquids, and thats why only they get pulled apart........hope ive helped u.
(ps your 'liquid' spelling is wrong.) :)!!!
