1. The Drink Up Life Long Batch No. 1234Z Unauthorized readers will be prosecuted

2. Problem with the water  Grey and white solid found in water  yellow liquid on top of the water  Strong alcohol smell

3. Grey solid  The magnets on the desk keep attracting to the grey solids Our Hypothesise: The grey solids are made of magnetic materials

4. Solution to grey solid  We can make use of the magnetic properties of the grey solids to remove Them  We will use giant magnets and remove the solids by placing the magnets above the tank of water

5. White solids  The white solids are in the water, not dissolving Our hypothesise: The white solids are insoluble, thus we can use secret method X

6. Solution to white solids  As the solids are clearly visible in the water, which prove that they are insoluble, we can use filtration(Secret method X).  We will get a big tank with a layers of filter paper, and slowly empty the water into the tank. We will get a wire gauze to support the filter paper.

7. Yellow liquid  A layer of yellow liquid is found on top of the water, not mixing with the water Our hypothesise: The yellow liquid is of a different density as compared to the water, so we can use our secret weapon.

8. Solution to yellow liquid  As the yellow liquid is of a different density as compared to the water, we can use the separating funnel.  We will make a large separating funnel and we will separate the yellow liquid from the water.

9. Strong alcohol smell  There is a strong alcohol smell in the water, so the water might be mixed with alcohol Our hypothesise: We can use the power of heat to remove the alcohol

10. Solution to alcohol smell  As we suspect that the alcohol smell comes from the alcohol that is mixed with the water.  We will boil the water at 68 to 78 degree Celsius, so as to evaporate the alcohol, but retain the water.

11. For safety precautious  For safety measures, so as to remove any other unidentified pollutants, we will use distillation to distillate the water, in order to obtain pure and clean water.
