Does my boyfriend love me?

Me and my friend are doing an extra credit prodject in science cl. If completed and completly works we will get 10 points added onto our final average. We need to build a purification system that can filter out an entire happy meal (cheese burger) all we know is it has to go through a smell test, it has to look clear, salt and chlorine test and lastly a greese test. We need to have a half a liter of clear and nice water. The question is how and what materials do we need? specifically step by step please?
