Problem Develop a new way to help keep houses afloat in flood

conditions.

Must be made from recycled materials.

Approach Water bottles to provide buoyancy

Duct tape and string to hold the water bottles together

Constraints Must be able to hold 45 lbs securely afloat

Made from 75% recycled materials

Have little or no cost to build

Location Egypt

The Nile runs through it

Has experienced a lot of flooding

Materials 1 Cardboard box

67 Water bottles

Duct Tape

String

Garbage bag

Construction House Represented by the box

Water bottles provide the ability for the house to float

How much can one water bottle hold?

House

Calculations Found out that 1 water bottle holds about 16.9 mL of

air.

We then found 1 mL of air supports up to about 32 grams of weight, or 1.12 ounces.

1.12 oz x 16.9= 18.928 or about 19 ounces or 1.2 lbs

So 1 water bottle holds about 1.2 lbs

Results After testing our prototype, we found that our design

did meet our requirements.

Held our 45 lb objective, at a 1/100 scale showing the actual model will hold about 4500 lbs.

Made from a 75% recycled materials

Almost no cost
