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
