You could let the oil float to the top and skim it off.
Not really, The best way is to use a separating funnel.
oil and water will naturally separate over time because oil is less dense than water
Oil float over the water surface; use a decantation funnel for separation.
You just need to use filter paper. use the filter paper than just pour the water and sand on the filter paper. the sand will go to the filter paper while the water will go straight to the beaker or anything below it. That is how you separate it. To separate sand and water you could pour the mixture through a filter. The water would pass through the filter but the sand would remain on top of the filter. If you didn't need to save the water you could evaporate the water and leave the dry sand behind. Or allow the sand to settle and carefully pour off the water first. Then allow the remaining water to evaporate.
First, use a magnet to get the iron nails out because iron is a magnetic material and will be attracted to the magnet. Now what you have left is the water and oil. Fortunately, oil is less dense than oil and it will float on top of the water. Use a separating funnel to tap the water out from the bottom and collect it in a container. You can also use a spoon to get the oil out from a container which contains the oil and water since oil floats on the surface.
Oil naturally separates from water and then may be skimmed off the top. For further purification, heating the oil allows the remaining water to evaporate.

this is because it does not decompose by heating
You can let the oil float to the top or you can use fairy liquid.
The most simple methods are decantation and filtration.

oil
No. You should use evaporation of the water to separate the sugar and water.
It is more simple to use a separation funnel.
you could uses a sponge or use oil
You could use the separation techniques of either distillation or a centrifuge.
