A mixture of sand and gravel is commonly used in construction. By using a wire mesh, the two materials can be separated.
One way to separate iron nails and salt is by using a magnet. Since iron is magnetic, you can move a magnet over the mixture and the iron nails will be attracted to the magnet, allowing you to separate them from the salt. Another method is to dissolve the mixture in water, as salt dissolves readily, and then use filtration to separate the solid iron nails from the dissolved salt solution.
Yes. a candle turns chemical energy into light.
For the nails, you can use a magnet. You can separate the marbles and corks by putting it in water, wood floats and marbles don't.
Use scented oils!
You can use a coffee filter in first than put your water in than the gravel and that is how you separate gravel and water...:) or you can get a screen like a drainer and pour all of your gravel and water in that.....:)

use a magnet
Use a sieve to allow the sand to pass through, leaving the iron nails behind. Or use a magnet to attract the nails and remove them from the sand.

You could use a magnet - if you have one!
If we need to separate sand and gravel, we simply use the size of the material and a mechanical contraption to do the separating. A screen with mesh of the proper or appropriate dimensions will sieve the particles nicely. The sand will fall through the mesh piling up underneath it, and, if the screen is tilted, the gravel will bounce its way down and off the screen into a separate pile.
Use a centrifuge. Magnetic separation will not work if they are brass nails.
You would use a filter in this case a grate bigger than the the sand yet smaller than the gravel that you could probably buy at your neighborhood grocery store or online.
You can use magnetism because if you do use this technique the iron will get magnified and then it will separate from the aluminum. Source: I'm a GENIUS!
you can use a heater and don't use my answer because it is absolutly wrong (says elizabeth pham)
