How could you separate white sugar from flour?

There are several methods you can use to separate white sugar from flour:

1. Sieving: This is the simplest method. Here are the steps:

- Spread a piece of cheesecloth or a fine-mesh sieve over a large bowl.

- Pour the mixture of sugar and flour onto the sieve.

- Gently shake or tap the sieve so that the sugar passes through the holes, while the flour remains on top.

- Transfer the flour from the sieve to a separate bowl.

2. Air Separation: This method utilizes the difference in particle density between sugar and flour:

- Take an empty container with a lid and place a fan or blower near its opening.

- Pour the sugar and flour mixture into the container and switch on the fan or blower.

- The air current will carry the lighter flour particles away from the heavier sugar crystals.

- Collect the separated sugar at the bottom of the container.

3. Floatation Method: This method takes advantage of the different solubility of sugar and flour:

- Fill a large bowl or container with water.

- Add the mixture of sugar and flour to the water.

- The sugar will dissolve in the water, while the flour will float on the surface.

- Carefully skim the floating flour from the water.

- Strain the remaining water to collect any remaining flour particles.

4. Magnetic Separation: This method works if the flour contains wheat or other grains that are magnetic:

- Obtain a magnet strong enough to attract wheat or flour particles.

- Hold the magnet near the mixture of sugar and flour.

- The magnet will attract and hold onto the flour particles, while the sugar remains unaffected.

- Gently remove the magnet and collect the flour that has been attracted to it.

After using any of these separation methods, it's important to ensure the separated sugar and flour are completely dry before using or storing them.
