Separating a mixture of sand salt sugar and pepper is easy, first off pepper floats so put the mixture into water and occasionally stir until all the pepper is on top. Then you can decant the pepper off, then you put the leftover mixture and water into a filtration system, the sand will be filtered out while the sugar and salt will have dissolved into the water, and lastly if you evaporate the water then mix the sugar and salt mixture with ethanol, the sugar is more soluble in it than the salt is.
