Use a strainer and strain the soup into another bowl. The oil will be left in the strainer.

You can also use an oil skimmer. An oil skimmer is a device designed to remove any oil spills floating on a liquid surface.

Use your hands to hand pick the metal. It is not practical but it still works (just not as effective).

Use a fine sieve and pour the coffee into the sieve. The last chunky bits of residue will remain the sieve and the coffee will end up in the cup.

When you have a coffee drink you can use a metal mesh filter to press down to squeeze the rest of the coffee out before you pour it into a cup.

Distillation - There might be a chance that distillation could work if coffee bean isn't flammable
(prob doesn't work)

Filtration-
Filtration is the best method because coffee grains will remain as residue and coffee solution can be easily filtered through filter paper.

We could use a strainer to drain the coffee drink and let it pour in a cup and the coffee grounds are left in the strainer. Then you can throw it away.

Filter paper - you can pour the coffee through the filter paper into a cup. It will filter out the larger chunks of the coffee.

Using a separating funnel, we can separate the two liquids as water   and oil are fully insoluble, they split into two distinct layers.

You can separate water and oil by gravity filtration. It will oil purify and separate heavy, oil/water mixtures.

We can cool the soup, and the fat in the oil will float up to the top and can be easily removed.

We use a big electromagnet put onto a crane. When the crane is lowered then all iron scraps cling onto the magnet.

You can also boil it and cause it is less denser, it will float to the top! Since the oil is lighter, it is less dense than water and floats on water.

- make a big magnet and move around the waste using a crane to collect iron/metal

- Use ice to freeze the oil that's on the surface of the water.
- You can wait until the water gets colder so then the oil hardens, and you can scoop it out
- If you boil it (like hotpot) the oil floats to the top because its water based.

Use an ice cube and move it on top of the soup to remove the oil.
