DOCUMENTATION OF DESIGN

ORIGINAL DESIGN

We thought that if we covered the can with cotton balls, put it in a oven mitt and ripped up pieces of emergency blanket, we could keep the can at the same temperature. This would of kept the can warm for little while, but not long enough.

ORIGINAL SUPPLIES

We used cotton balls in our first box. They minimize heat transfer. We couldn’t use them the secong time because they take up too much space. We planned on using an

oven mitt. We decided against it the second time so we could use the foam.

We first only used duct tape to around the box to hold the box together

We first just stuffed the emergency blanket in the box

ORIGINAL MODELS

This is the original model of the boxThe edges didn’t fit because we didn’t measure it right. Each side of the box was a different size and we would have had to tape up the holes with duct tape.

We just stuffed cotton balls and emergency blanket in there with the can. This wouldn’t have worked because the top of the can wouldn’t be covered and it would leak.

REASONS FOR ORIGINAL DESIGN

For this project, we decided to put the can in a burner glove and surrounded the glove in emergency blanket. In all the cracks and crevices, we used cotton balls. The whole thing was put into a foam box. To keep it waterproof, we put it into a plastic bag. We used a burner glove because they are made not to conduct heat. The emergency blanket reflects the heat back onto the can. Our hypothesis is that the emergency blanket will reflect the heat back to the can and the glove will keep the heat trapped in the emergency blanket.

NEW SUPPLIESGorilla Tape • “Duct tape on Steroids” • Very sticky

Spray Foam Insulation • It is used for sealing roofs of houses, so if must be

strong • Great for filling gaps and cracks

Emergency Blanket • It reflects the heat back on the can

Foam Board• Used to make outside shape because it was thin

FINAL DESIGN

We used a lot of foam, an emergency blanket, gorilla tape, and a more hand crafted box for our final project. We make sure the can was stuffed air-tight in the box and that the lid was secure during our experiment

STEPS TO MAKE FINAL PRODUCT

1. Build the box to the right dimensions 2. Cover the box in duct tape 3. Cover the box with a Ziploc 4. Cover in gorilla tape 5. Surround an empty soda can with

emergency blanket 6. Spray foam around can 7. Cut off edges and tape down 8. Cut a piece of foam board and cover with

emergency blanket. Tape down for lid. 9. Punch hole in top for thermometer
