The document describes the design and construction of a challenge project to insulate a can. Key details: - Materials used include styrofoam, bubble wrap, a safety blanket, and packing peanuts. - The styrofoam formed the rigid outer shell. Insulating materials like the blanket and bubble wrap were layered inside. Peanuts filled gaps. - The design process involved cutting and shaping the styrofoam shell, preparing insulating fillers, and sealing it together with tape and glue. - Testing involved placing a hot can inside the insulation and submerging it in cold water to evaluate heat retention.

2. Materials Used
• Styrofoam poster.
– Exterior of the insulator.
• Bubble wrap.
– Inside the insulator.
• Safety blanket.
– Inside of insulator. The surface of bubble wrap.
• Styrofoam packing peanuts.
– In the corners of the insulator.
• Duct tape and hot glue.
– Tape down the lid and seal the cracks.

3. Design (pt. 1)
• Styrofoam poster as the
outside core.
• Safety blanket on the inside.
• Bubble wrap over the safety
blanket.
• Packing peanuts in the
corners of the insulator.
• Hot glue to seal the cracks
and hold the thing up.
• Duct tape to attach a lid.

4. Design (pt. 2)
• The styrofoam poster board was the thickest layer, so we
decided to put it on the outside as the main structure.
• We decided to use safety blanket to line the inside of the
“walls,” because safety blankets can keep in heat well.
• Bubble wrap was put on top of the safety blanket to add more
insulation.
• Styrofoam packing peanuts (shown in the bottom right
corner) were used to surround the can.

5. Cutting the Styrofoam Rim
Francis is cutting out the walls of our project. We originally
went with 9.5 inches x 9.5 inches x 18.5 inches..

6. Arranging the Styrofoam Pieces
Here we are hot-gluing the pieces together. I am using a ruler
to make sure we glue straight.

7. Cutting Down the Box
Our design ended up being too big, so we cut it down with a
box cutter.

8. Preparing Insulating Materials
While Nathan cut the box down, Francis arranged and
measured out the insulating materials to put in the box.

9. Finishing the Box
Trimming down the box. Final Box’s shape before adding the insulators.
dimensions were 9 cm x 9 cm x 19 cm.

10. Final Project Outside
The design was essentially a box stuffed with insulating
materials. Nathan decided to add extra designs.

11. Final Project Inside
A view of what was inside our final insulator.

12. Testing the Can
Here we are testing out insulator with other projects. We put in a
can full of hot water, and then put out insulator in ice cold water.
