Week Two (April 10th, 2018 - April 16th, 2018)

This week we finalized the materials for our water purifying design. We discussed multiple different approaches to tackle the best way to purify the water, but next week we will test different ways in the lab to achieve the best solution. We came up with the following list: 

• 2 Liter Soda Bottles (2)
• Gallon size water (1)
• Coffee Filters
• Charcoal 
• Rubber Bands
• Unglazed ceramic plate
• Cotton makeup wipes / Cotton balls
• Medical tape/duct
• Legos
• Crushed Stone

We came up with a few design ideas for our water purifying device in case of nuclear war. This encompasses all of the parts of the design and it is more compact. This is the first design:

 

This is our second design, it is comprised of multiple systems. So, that the water can be filtered perhaps more thoroughly.  

Overall, we will definitively test out different methods in order to find the best solution to purify the water in the three different stages.
