Dear City Official,
I understand that you have a problem and I am willing to help. To solve your problem, I will conduct a series of expirements. The first step is to add water. The density of milk jugs are .95 g/ml. All the other materials are over the density of 1 g/ml. As a result the milk jugs powder will rise and you may seperate the milk jugs from the other materials. When that is completed, use the tank labeled "Concentrated sugar water, density = 1.5 g/ml" and add the other three materials with the sugar water. Since the density of the soda bottles are 1.4 g/ml and the density of the sugar water is 1.5 g/ml, the soda bottles will rise. As a result, you will be able to collect the soda bottles. To seperate the steel cans from the aluminum soda cans, you must use your magnets to bring up the stell can powder. Once the steel cans are eleminated, you will be able to collect the remaning aluminun soda cans.
Sincerly, Aamir Rupani
