9.3. The top "sitting" compartment can be swung back due to a hinge and will rest onto the flattened cans, forming a fold-able stool.

10. How we made prototype 1

10.1. Drill holes into 8 popcans using the electric drill

10.1.1. Two holes per can

10.1.2. Each hole approximately 2 cm in diameter

10.1.3. Holes are on opposite sides of each can and approximately in the middle of the can

10.1.4. Send bungee cord through the holes to make a more stable base

10.2. Superglue two cans together

10.2.1. Superglue the top rim of a can with no hole and stack the can with two holes on the top

10.2.2. The result is 8 stacks of cans

10.3. Remove one hook from the end of the bungee cord and thread it through the holes made in the cans

10.4. Cut two circles out of the pizza box cardboard

10.4.1. Circle should be approximately 12 inches in diameter

10.5. Cut the thin cardboard into rectangular strips approximately 1 by 12 inches

10.5.1. Make approximately 40 of these strips

10.6. Roll the strips into thin cylinders and reinforce with duct tape

10.6.1. Adding a cushion using clothing and stuffing it with halloween spider webs

10.7. Tape the cylinders onto the pizza box circle vertically and place the other pizza box circle on top, reinforce with duct tape

10.7.1. Result is cylinders sandwiched between two pizza box circles, creating the stool seat

15. Build Instructions FINAL

15.1. Clean and dry 40 soup cans (284mL)

15.2. Use the PI glue to create 10 columns of cans. Each column is 4 cans in height. Then wait at least an hour for the cans to dry

15.3. Using an X-acto knife carefully cut away excess glue

15.4. When dry, on the top and bottom can, drill two holes on opposite ends of the can approximately 1.5 cm in diameter. Make sure the wholes lie in the center of the top and the center of the bottom can on both side, approximately 6 and 1/2 cm from the top of the can.

15.5. Spray paint five of these columns an ugly blue and the rest beige

15.6. Place duct tape around the sections that connect the cans together for further reinforcement

15.7. Remove the hooks at the ends of both bungee cords. Tip: buy the bungee cords with removable plastic hooks instead of the metal hooks, they are easier to remove and cost less.

15.8. Thread one bungee cord through all the top cans, and one bungee cord through all the bottom cans.

15.9. Cut the cardboard of the cereal boxes into 1" by 12" strips, to roll into little cylinders. Create approximately 100 of these small tubes

15.10. Cut out two circles from the pizza box, 12" in diameter for the seat

15.11. Use glue to stick the tubes vertically on to the seat. Then attach the other circle on the top to finish the seat

15.12. Using the Halloween spider webs, pull and stretch to create an appropriate volume and cushion for the seat

15.13. Use the hot glue gun and duct tape to attach the spider webs to the top of the seat

15.14. Place the towel on top of the seat and use glue and staples to ensure the towel remain in place. Cut and shape the towel as needed to cover the whole seat and remove excess folds.

15.15. Add velcro pieces on top of all ten cans and place the appropriate opposites on the under side of the seat.

15.16. Tie tight knots onto the bungee cords for maximum stability and to prevent slipping of the cans

15.17. For the remaining two strips of velcro attach two on the one column of the stool and the opposites on the bungee cord ends so the stool can be fastened and de-fastened easily.

15.18. CONGRATULATIONS. The stool is complete. For further instruction on how to use it, refer to the section titled "How to use it"
