Backpack Body

Fold a piece of paper towel twice lengthwise and tear into three equal strips.
Place a large plastic sheet on top of the 2x4’s to prevent mess.
Cover Xerox box with plastic wrap and place on the 2x4’s.
Mix glue and water in a large container to a 1:1 ratio.
Pour mixture into small, clean, yellow trough (if it is still here.)
Dip paper towel strips in mixture and place on the box vertically (always in the same direction.)
Put on 1 layer then let dry for 1 day.
Repeat steps 6 and 7 until desired thickness.
Remove the box from the interior.

Clean the 2L pop bottles and let dry.
Center the two pop bottle lids on the block
Draw a circle around the centered pop bottle lids
Drill a hole in the circled area 1 ½ cm wide and 1 ½ cm deep.
Fill the hole with hot glue and center the cap inside the glue so the bottles can still be attached.
Put a screw through the center of the cap while the glue is still hot to keep it attached better.
Wait for it to cool.
The oxygen rig is now ready.
Make sure the bottles don’t get permanently attached to the caps, you won’t be able to change the oxygen anymore.

Take the metal panels off the floppy drive.
Place the sublimator where you want it and drill 4 holes in each of the corners through to the backpack.
Use the nuts and bolts to attach the metal panel to the backpack.
Repeat for each backpack.

Cut the entire bag part off of the backpack; keep the straps and the part holding them together.
Drill holes in the top of the backpack to match this.
Take apart the strap connection and insert as seen above.
Reattach the strap connection.

Congrats on your now wearable backpack. Good luck in space!
