Plastic Soda Bottle Lid Capsule

Step 4: The finished result

This was a quick little project and a lot of fun to make.  My seven-year-old son, Jack, helped me with some of the steps and watched throughout the entire process.  He thought it was pretty cool to make a little piece of gear out of something else that we would normally just recycle.  I probably won't be making a lot of these or using them for everything, but it is a useful little container and is very strong.  I could see this being used as a container and float for a small fishing kit.

If you have some time and a few spare plastic soda bottles laying around, give it a try.  After making this one I made another one with an additional flat piece of plastic sandwiched between the two necks that created a dual compartment container. I think I'll use it for salt and pepper!

This is so cool! I am running to rescue stuff from our recycle bin!

We've always made a ton of these in our group, but we glue plastic in the middle section so that each side is divided. Each side holds a different spice for camp cooking.

Is there a way to make it longer say ... for matches??

[TheMaker888]

WaterProof i presume ?

[bfgreen]

You presume correctly sir, else what is the point?

This would make a good water tight pill container or something. So many things this can do we haven't discovered yet! Maybe you can roll up your bills and make this a wallet. A water proof wallet...

[silverassassin3]

it probabley would work as a wallet, but it would need to be bigger, because you would have to fold the bills pretty small. so i might just brain storm to think of a slightley bigger version, but still make it pocket sized.

Now you are talking. When I was young in Military Leadership school they had us practice brainstorming. It was along these lines of taking something strange and giving ideas on what to use it for. No laughing at each others ideas, just idea and write it down. It was just amazing how much we came up with with all of us giving ideas fast and furiously. A waterproof wallet is an excellent idea, easy to store as well.

There's a whole sub-thread below about using this as a pill storage container. That's what I originally made mine for.

[chevhunter]

that is a great idea. i'm thinkin i'm gonna be building one with the two compartments for muzzle loading. one side for extra primers and on the other side will be some bore butter. ( instead of taking the whole squeeze tube with.)

Thanks! If you're looking for a way to re-package creams or greasy items, check out one of my other Instructables on that topic: DIY Single-Use Antibiotic Ointment Blister Packs. It might help you with what you are looking to do :-)

another thing they could be used for, key/keys for a boat to act as a float.

[K'nexFanatiFreek]

better yet: combo float and boat (and motor if applicable in your state) registration holder

[Hippymike96]

for all that you could just put it in the bottle its self!! :D

[bfgreen]

True the container is buoyant and water tight. Even more possibilities..

[Hippymike96]

Humm.....

[FrozenIce]

hahaha i love this :) so usefull, so compact, so POCKET SIZED :D just what i need :) might make a couple of them if i have the time.. or maybe more then just a couple...

Another win Brian! I have some store bought containers about that same size but the lids don't stay on well. Another con is that they are heavier than your cap container. I have a feeling your Ibles are going to get me in trouble with my wife. :)

[bfgreen]

Thanks Frank! Not much I can say about your wife giving you a hard time, other than "welcome to my world." ;-)
