Here are some scenarios when it comes in handy:
- Camping: not having to go out of your tent to pee when it's cold
- Peeing off a boat/kayak on a boat trip
- Group hikes: not having to find a place to squat and pull pants down in private
- Side of the road: no rest area in sight, desperately needing a pit stop
- Public bathrooms that are just too gross to sit
- Little girls on long car rides who just can't hold it long enough
- When you are outside and it's cold, and you don't want to strip to pee
- In a train compartment
If you prefer making something pertaining to what goes into your body rather than what leaves it, check out my other duct tape instructable, my woven duct tape berry-picking basket.
Step 1: Materials
• Duct tape. This can be an 8.5 x 11" sheet plus a roll, or just a roll.
• Transparency film or acetate
These instructions will focus on using the duct tape roll. The advantage of a sheet is it leaves fewer ridges for stuff to get into.
Step 2: Duct tape base
Then lay four more overlapping strips face down, so they stick to the face-up strips.
Voila! A duct tape sheet.
Step 3: Tubing
Tear off about 2" of duct tape. Wrap it around the tubing about 1" down. Fold the other 1" over so the sticky side is out.
Step 4: Shaping
Fold the sheet in half. Place the tube inside the sheet so that the duct tape sticks to the walls you have made. Cut on a diagonal up from just above the tube to a couple of inches back from the tube.
Tape over the top of the fold from the tube back toward the rear.
Step 5: The back
Use tape to cover the hole on the outside, then the inside.
Step 6: Little touches
Add tape on the inside using little strips to make the path to the tube nice and smooth.
Step 7: Stiffening
Step 8: Testing/tweaking/tips
- Whether you make your own or buy one, be sure to test it at home before going on the road. Have children test it too. You may even find leaks you can fix before you travel.
- My tubing was curved the wrong way, so to fix that, I waved it about 6" above a gas burner, very cautiously, to slowly warm it so I could bend it back. This took time and patience, but now it's great.
- Remember that urine is sterile. Keep the PSU in a freezer bag when on the road, then just rinse and let dry. It cleans up easily.
- If you are concerned about urine collecting in tape overlap, try spraying on some sealant.
