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 a hundred
and fifty grit sandpaper until they’re
perfectly flat they don’t have to be
smooth though in fact the rougher they
are the 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 calves
now to make this thing as strong and
lightweight as possible let’s try
bonding it with a two-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 two 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 clapping 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 and tell the epoxy hardens you can
see here how the epoxy at the bottom has
completely sealed everything off
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 two caps
and some hot glue it won’t be as strong
but you can make them start to finish in
under three 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 fourteen grams but
they can still hold up to ten
milliliters 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 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
multi-purpose 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 you’ll
like some of my others check them out at
the king of random calm hello my random
citizens hey guys I hope you enjoyed
this soda cap container project and I
want to let you know it works with water
bottle caps as well so if you don’t have
any soda bottles just go find a water
bottle it’ll work the exact same way did
you like this video as always I’ll be
looking for your comments below and if
you’re checking out this t-shirt
wondering where you can get one I’ll put
a link for that in the description as
well thanks again for joining me in this
project and I’ll see you around for some
more random hacks of science in the next
project video I’ll see you there
