STEM Concepts
Things we needed to know prior to constructing our prototype include the water weight we need to hold, ways to keep water hot or cold for long periods of time, and how to pressurize the water. Also we need to know what type of insulation to use, what type of shower head would provide optimal water flow, and the ergonomics of the device. Lastly we need to figure out how to attach it to a vehicle.
Prototype Stages
Before Covid-19 our product was going to be made out of two pvc pipes, with the rest of the attachments fitted into them. The pipes would've been measured and cut to our specified length and one of the two would've been painted black. The other pipe would've been fitted with some type of insulation as well. The attachments that went into the pipes would've been outlets for the water, a shower head and a faucet, the inlets for the water, a valve for pressurizing, and the handles for moving. We would've had to cut some of the pvc with saws, drill pieces together, as well as use glue/caulk to keep the seals water tight. Once the two pipes were finished and fitted with the attachments we would've mounted the wheels on them and added mounts to attach the pipes to the vehicle. Some of the testing we would've conducted for the product would have been initially filling it with water to make sure the containers were water tight. After that we could've weighed them, pressurized them, and tested the outlets. This would help us ensure that everything worked as well as be able to collect data for how much water fits in the containers, how much it would weigh, how much pressure it needs, and how well the water flows.

For our new Covid 19 product we are going to use paper towel sleeves to act as the pipes that would of held the water for our shower and drinking water. We are going to use other sheets of card board to act as our support for holding the paper towel rolls up. For the hose we found a wire that looks proportionate to the design and added a shower head too out of paper. We cant run any test on our product as it cant actually hold water now. If we did we would test how cold we can keep the drinking water and how hot the shower water is. Also we would need to run some test to see how much water pressure we can have in the pipes before they break.

Introductory Letter to Advisor
Dear Mr. Earl Gwin,
We are currently working on our senior year capstone project at Worcester Technical High School as a part of the Pre-Engineering program. Our group consists of Eric Gwin, Ryan Ethridge, and Ethan Kalchthaler. Our project aims to create a product which would allow for easy transportation of clean drinking water as well as warm showering water on your vehicle while participating in outdoor activities such as camping, driving on the beach, or attending music festivals. We believe that in order to create the best product possible that is of high quality we need the advice of an expert like yourself. We would like to ask you to represent our group as a mentor and give advice to further our research and development of our project and product.
Respectfully,
Eric Gwin, Ryan Ethridge, Ethan Kalchthaler

Equipment/Items Needed
For the creation of our product there is almost no technology or software that is needed. Our design is simple enough that the only necessary equipment would've been hand tools including a saw, a drill , screws, a measuring tape, and a wrench.
