How to Make a Soda Cap Container!

If you’re on a hike, or caught in a survival
situation, it’s really helpful to have containers that are lightweight and weather resistant.
So in this project let’s turn a couple of empty soda bottles, into compact, lightweight,
and waterproof, soda cap containers. Let’s start this project with a hotel key,
and a couple of plastic soda bottles. The first thing we need to do is cut the tops
off, and if we turn them upside down and clamp them in a bench vise, it should be incredibly
easy. Now if we use something like a hacksaw, we can use the bottom side of the flange as
a cutting guide, and the goal here is to make the cut as clean as possible. When we’re through
to the other side, let’s double check the flange to make sure it’s completely flat,
and if there are any ridges, we can easily shave them down with the saw blade. Now we’re gonna need a second cap, and this time I’m using a bottle with a black lid just for
a little variety. This should allow us to color code the two ends of our container.
Now depending on your purpose, it could be extremely important that the lids sit perfectly
together. And to make sure that happens, let’s go ahead and sand the bottoms with something
like 150 grit sandpaper, until they’re perfectly flat. They don’t have to be smooth though.
In-fact, the rougher they are, they better they’re gonna bond with an epoxy. While
we’re here it’s a good idea to roughen both sides of our hotel key as well, so let’s go
ahead and do that, then carefully trace around one of the caps with a marker. As we cut it
out, you can see we’ll end up with a plastic disc the exact same size as the caps, and
this will become the divider that splits our container into two separate compartments.
Now to make this as strong and lightweight as possible, let’s try bonding it with a 2
part epoxy. This will need to be blended thoroughly for about a minute to make sure it sets up
properly. Now, without wasting too much time, let’s apply a liberal amount of epoxy to the
base of the caps, then carefully set the round divider on top, and press it into place. If
you already have epoxy on the other cap, just join it to the other side of the divider,
and simply leave it to harden. In about 2 hours, your container will be firm enough
to handle, and a few hours after that, it should be fully ready to use. Now for an even
stronger bond, try clamping both caps so they set together under pressure. If you don’t
have a bench vise or a set of bar clamps, try using a rubber band to keep things tight
until the epoxy hardens. You can see here how the epoxy at the bottom has completely
sealed everything off. That means this container will hold two different items, and keep them
completely separate. Now I added some special ingredients to mine and tucked it away in
one of our first-aid kits to help out in emergency situations. This will give us the power to
ignite a survival fire, without ever having to strike a match. Look for how this works
in the matchless survival fire project. I also tried another variation and found the
simplest container could be made with 2 caps and some hot glue. It won’t be as strong,
but you can make them start to finish in under 3 minutes. This version is still super lightweight,
water resistant, and will work really well for storing things like pills or small candies.
You can see it’s hollow all the way through, so the contents can be accessed from either
end. This works well to protect your matches from the elements, or even make improvised
hide and seek containers for geocaching. If the container ever does get wet, everything
inside will be kept safe and dry. Now both variations weigh only half an ounce, or about
14 grams, but they can they still hold up to 10 ml of fluid, which is the same amount
as both of these glass bottles put together. By the way, if you epoxy the two bottles end
to end, you’ll have another variation that still looks really cool, and will last for
a really long time. Well now you know how to turn two empty soda bottles, into lightweight,
multipurpose containers, that don’t really cost anything to make, but will do a great
job protecting your stuff. Well that’s it for now. If you liked this project, perhaps

  1. Ideia genial! Ótima forma de aproveitar garrafas pet. Suas tampas são excelentes para , como no exemplo do vídeo, serem muito úteis para guarda de comprimidos, etc.

  2. You can glue the caps together over and over again to make a multi-compartmentalized walking stick! Get the picture?

  3. Me and my dad made these. We used waterproof epoxy meant for jet ski repair and other things. And we also used his old MasterCard to make them. It was perfect for anything and it's so convenient! Thanks Grant!

  4. I like this guys projects and I like his delivery. I like how he says "let's do this, let's do that" so people don't feel condescended

  5. You could also paint the spacer with little pictures of what is inside so when the container is empty, you’ll see the image and never forget which side is which. Plus it would look cool

  6. I needed some larger containers so I used Gatorade caps instead. i suppose you could even uses something like a plastic mayonnaise container and make extra large ones.

  7. Nice I actually made something before king of random did lol.
    I have them in my YouTube videos.
    I made them for containers and to have diff stuff of mine screw on and off each other

  8. I have successfully used a PVC pipe cutting (the plier looking ones) to cut the tops off. Works super slick and nice clean cuts too.
