PUTT PUTT SWAG
Story
The year is 2008 and there has been a total shut down of power-gas and electricity. As a result many forms of normal transportation have now become obsolete. The government has asked the public for help in the development of transporting vehicle's that can only use steam power. Since you are from newfoundland then you figured it would be best to use something that can be used on the water. The government has suggested that steam power be used because it is cheap and will not require the need for electricity. Another stipulation that the government has it that the device prototype can only be made of recyclable materials. You wonder at what such an opportunity will have for you as you gaze around your garbage scanning for the materials that you might use to develop the ideas brewing in your head. You note some plastic pop bottles, popsicle sticks, cardboard, glue guns and glue sticks, pop cans, juice cartons, candles, and duct tape. This is perhaps all that you will need in order to create you one-of-a-kind steam powered boat.
Step1: Identify Problem
We need to make a putt putt boat for the government to help with steam powered engines for transportation where power-gas and electricity has been shut down. We need too creates a few designs and chose one to make from recyclable material.
Step2: Design Brief
We are making our putt putt out of a milk carton and using copper pipes and a candle.
list of materials:
- 2 straws or 2 copper pipes
-milk carton
-playdoh
-candle
-tape

We found out that we can build two types of putt putt boats one with a coke can
and one with copper pipe. Our source of heat is gonna be a candle.

Step 4: Generating Alternate Solutions
Questions
1. Is the design practical? 2. Will the design cost a lot of money? 3. Is the design reliable? 4. Is the design durable? 5. Is the design visually appealing? 6. Is the design safe? 7. Are the resources available? 8. Are the tools available 9. Can the design be created on time? 10. Does the solution meet the needs? TOTAL: |

We have chosen sketch number one because it got the most score when we answered the questions and also we have all the materials and are familiar with how it works and how to create it. Its the most practical for what we need to make it for.
Step6: Developing The Solution
Step6: Developing The Solution
Step7: Testing and Evaluating
We used the same design as sketch number one but we used a milk carton instead of Styrofoam. Yes it worked as predicted but it took long for the heat source to heat the copper pipe to the right temperature to make the boat work. Yes are design was as reliable as we thought because it worked good ands lasted for a pretty long time so the copper tube could hold the water good as we expected. Are design worked the best because it went the fastest. The can design wasn't the best because there became a problem where the putty leaked and couldn't hold the water.
Step8: Resigning and improving
Some small things we would do to improve are prototype is we would put more putty and find a better way to fill the holes in where the boat leaked too. Also we would coil the copper pipe better and closer together so the heat source can heat a bigger part the pipe at once!
Brief Summary:
We made a prototype as you see in the pictures above. Are putt putt boat was made from a litre milk carton sliced in half to create that boat shape. We coiled are copper pipe with a broom handle for our motor and had to end pipes to stick out the back of the boat as a source to propel the boat. We covered the seams with putty to stop the leaks. and filled one of the end pipes with water to fill up the motor. We used a tee light candle to heat the copper pipe to make the water boil and 'power' the motor. Are boat worked as we predicted!
