Well to be honest I have no idea how much an empty toilet paper roll weighs other than to say it weighs close to the same as an empty water bottle.

Empty water bottles weigh about 1 oz.

Good luck

1.) Jumper cables (aka booster cables) 2.) Multi-Tool (one of those pliers that have tons of tools in the handle) 3.) Map (local area or area you’ll be traveling) 4.) First-aid kit 5.) Flashlight (and extra batteries) 6.) Rag 7.) Duct tape (because you can fix a lot of things with Duct tape) 8.) Rain coat (the folded $1 type) 9.) Emergency blanket (the folded $1 type) 10.) Folding shovel (entrenching tool) 11.) Fuses for fuse box 12.) Water bottles 13.) Protein bars or M.R.E. (meal-ready-to-eat) 14.) Reflective tape or reflective triangles (flares are hard to find) 15.) And old phone. Grab a $20 pre-paid phone(w/ roaming), because $20 is cheap insurance. 16.) Lighter or water proof matches, or flint rod. 17.) Compass 18.) Matches (for a fire) 19.) An orange vest if you need to stop on the side of the highway and get out of the car (a workers bright neon orange vest) 20.) Paper plates, cups 21.) Paper towels and toilet paper 22.) Sleeping bag 23.) Tooth Brush and Tooth Paste. There is a large possibility that you probably will skip brushing your teeth for a day in case of emergency and lack of water 24.) Kitchen Knife 25.) A 5$ Pan 26.) Ramen Noodles 27.) A few trash bags (shelter, poncho) 28.) A duraflame log (it burns for up to 3 hours and you can get them at your local grocery stores) 29.) A can of gasoline 30.) Signal Sparks I hope this helps: I have one of these myself By the way, choose and pick from this list, because I noticed that you said “Light Weight”

Single ply. Double ply. Tripple ply. Toilet paper?

6 oz. 8 oz. 12 oz. 16 oz. Water Bottle?

The toilet paper wrapper should give you the “weight” of the

roll, plus the number of sheets in the roll. so now all you have

to do is to “is the math.”

The bottle of water should tell you how many “ounces” of

water are in it from sentence two, above. so weigh the whole

bottle, with the water in it. Then pour the water into a plastic

bag. Weigh the water again without the bottle and, Wa-La.

subtract the difference. <}:-})
