Introduction: Waterproof Storage Tube

Picture of Waterproof Storage Tube

I thought of this the other day after watching the King of Random's video on how to make soda cap containers. I took his idea and changed it some.

Step 1: Tools/Materials

Pipe Cutter

Sandpaper (optional)


Plastic Soda Bottle


1/2 inch Plastic Pipe

Duct Tape

Step 2: Cut Off the Top of Bottle

Use the pipe cutter to cut the top of the bottle off. Hold the body of the bottle firmly. The pipe cutter will cut the top off but it will not be completely straight. That is fine for what we are going to do.

Step 3: Cut Your Pipe

Do a dry fit of the caps and decide where you want to cut it. I wanted to wrap duct tape around mine so I made sure to include it in my measurements. Use a marker to line up the pipe cutter with where you want to cut it. Then do another dry fit on the piece.

Step 4: Epoxy the Caps

I used a 1 minute epoxy to glue the caps on the ends of the pipes. I mixed it with a toothpick and spread it on the ends of the pipes. Then I put the cap on and rotated it to get as even a coverage as possible. Make sure you move quickly.

Step 5: Wrap and Store

I wrapped mine in duct tape, but I might make one wrapped in paracord. Then store whatever you can get to fit. This was a quick and fun project that anyone could do.

Im gonna do one with 5 lts caps to have more space inside

Good job, but I think you could reach the same result without effort by using a pills container as the one in this pictuce.

It is hermetical and has the silica into the plug that avoids the humidity!

I have something similar that I use for storage. Thanks for sharing. I like mine because I can determine the length and alter it for my own purposes.

If you want a hermetic seal just add some cork to the cap. Easy-Peazy- lemon-squeezy. ?

Nice instructable, Try a Medicine Bottle if in a hurry, the are also waterproof, but only for the short stuff.

I have prescription meds bottle from pharmacy that is orange and several inches high. I use some to store glasses, tubes of anti-scratch and antiobiotics bought over the counter, etc.

fschmitt2 (author)2016-03-31

Add some sticky backed sandpaper to the tube and have a striking point for your matches. Good size for small backpack kit!

That is nice. Thanks for sharing the black looks great.

bakdrft (author)2014-08-17

why not use PVC glue?

the pop bottle isn't pvc.

lilchumy (author)2014-09-10

I voted for your ible please vote for my "guide to fresh water fishing" ible registered in the hunter gather contest. Really appreciate it!

shed469 (author)2014-08-07

Excellent work and variation on the idea. Especially like your variation because I like working with PVC pipe and I have a cutter but might not have thought about using it to decapitate the soda bottles. Seriously doubt The King of Random would quibble over an Ible posted here without credit and link. He invites viewers to make their own and suggests other variations. As I recall, The King gave no credit to the inventor of plastic screw tops for soda.

static (author)shed4692014-08-09

Nor did the King of Random give credit the those who deleloped PET. ;)

ehudwill (author)shed4692014-08-09

Thanks, and I agree with you points.

IzNoGuD (author)2014-08-08

I bought some of these:

King of random had stolen directly from the Geocaching community ;)

good instructable

fgjill (author)2014-08-06

Stolen directly from the King of Random

tehbanz (author)fgjill2014-08-08

I prefer OP's version, more storage space.

ehudwill (author)fgjill2014-08-06

If you had read my opening paragraph you would see that I linked to Grant's video in my introduction and credited him as my inspiration. I did not steal anything. I used all my own pictures. I thought my idea was different enough that it deserved to be published.

Crucio (author)ehudwill2014-08-08

And it certainly does. Thanks for posting.

ehudwill (author)Crucio2014-08-08

Thanks for the support.

LittlestWorkshop (author)fgjill2014-08-07

Google image search bottle cap storage and then comment on the king of random's video to say he stole it.

mzmclady (author)2014-08-08

very nice....

First time I have seen this, and I will

be adapting and utilizing this idea... Thanx...

BTW, Pay no mind to negative nellies.....

There are those of us who are new to this

and appreciate the effort of others.....

ehudwill (author)mzmclady2014-08-08

Thanks for your support. Instructables is a great site. I have been here since 2007 and come here often. I wish I could publish more projects. If you have an idea we would love to see it.

Devasigamanisd (author)2014-08-07

Supper & Thanks

ehudwill (author)2014-08-06

If you had read my introduction you would have seen that I linked to that video.

samalert (author)ehudwill2014-08-06

Sorry didnt read it, saw few pictures and made my judgement. You are right, you gave the author credits.

Google image search bottle cap container, Grant did not invent this either.

ASCAS (author)2014-08-07

Three years ago I made a pocket-size spudgun using the exact sodacap hack. I've never thought of using it as a waterproof storage.

sunshiine (author)2014-08-06

Thanks for sharing! Have a super day.


ehudwill (author)sunshiine2014-08-06

Wow, thanks I will have a super day!

jmwells (author)2014-08-01

I have something similar. I use it to store an extra house key buried in the yard.

ehudwill (author)jmwells2014-08-02

That is a great idea. I plan on making several. I will have to make one for keys.

Housedog (author)ehudwill2014-08-06


I'm amazed at how many people will attack you on here because they didn't bother to read the intros, or previous comments. On a couple occasions I commented to the creator that they forgot something. They correct it, then I get a bunch of comments on how foolish I am for not seeing that the error is in fact correct! Lazy jerks in my book.

Fikjast Scott (author)2014-08-06

I really like this, the idea of using the cutter on the neck of the bottle is brilliant. nice work.

This is great. Thanks for sharing.

Why not just use a soda bottle pre-forms? You can find them 3 for a buck online.

ehudwill (author)Blue Hawaii2014-08-05

I already had the soda, epoxy, and extra pvc pipe laying around. I didn't have to buy anything I didn't already have.
