How To Make Targets Explode With A Sonic Boom


[Music]
hey guys this week I figured out a way
to turn these cheap disposable water
bottles into super awesome exploding
targets that go off with a sonic boom
I’m going to show you how to make them
these little bottle blasters are so
simple to make and extremely gratifying
the use for target practice because when
they get hit they let out a sonic boom
that sounds like gunshot and rocks your
world the best part is they’re
relatively safe to handle and
practically free to make all you need to
get started is a tubeless tire valve a
one and a half inch steel end cap and an
empty water bottle you can see these
valves are about one and a quarter
inches long and I got this pack of two
for about three dollars at a local auto
parts store all you need to do is drill
a 5/16 inch hole right into the center
of the bottle cap so once you get your
hole drilled out you might just want to
use a pair of pliers to clean out any
excess there get that hole about as
clean and smooth as possible this will
give you a little space where you can
pull the valve through if you grip onto
with a pair of pliers and tug it should
lock up into the neck and create an
airtight seal now the next step is to
drill a half-inch hole right into the
center of this steel plug so let’s go
ahead and do that next okay so now we’ve
got our finished valve assembly as well
as a 1/2 inch hole drilled into our
steel cap the only thing we need to do
now is bring the two together now to
make that happen just take the tip of
your valve and stick it into the center
of the hole lock onto the threads of
your valve with your pair of pliers and
just give it a little tug and you should
feel the valve pop right into place and
it’ll hold securely into the end cap and
that right there my friends is pretty
much it super low cost and easy to make
and that add an exploding target I need
to do is screw a water bottle into place
and go pump it up let’s test this thing
out now at this point you can pump up
these bottles with a bike pump and
they’ll be ready to go but just to take
things to the next level I created some
of these templates on Photoshop that you
can have for free simply cut them out
and wrap them around the bottle and you
can see it gives it a whole different
look with a professional-looking
built-in target how cool is that simply
take something like a bike pump and
attach it to the valve on the bottom and
we’re going to pump this up to about 50
to 60 psi but you don’t want to go a lot
higher than that not with a water bottle
you can see right between about 55 and
60 psi the bottle starts crackling and
it starts changing shape as well
you don’t really want to get it too much
more full than that this one’s ready to
blow up what would you compare that to
the gun shot down louder than the
gunshot that was right then add a sonic
boom oh my god now just for fun I went
down to the dollar store and found one
of these plastic sandcastles that I
tried using for a base which isn’t
nearly as practical as using a steel end
cap but it is a lot more fun
[Music]
now if you’re planning to use something
like a slingshot to set these off what
you really want to do is go round up a
handful of pebbles like these these ones
have really sharp edges that’s going to
be great for tearing open the skin of
those bottles okay so apparently rocks
and slingshots have no problem taking
out these targets so just for fun
we’re going to try blow guns next
now if you want to take things to the
next level you can stop by the dollar
store and pick up a pack of sidewalk
chalk like these and if you crush them
up into a fine powder and load those
into the bottles and when you hit the
target it explodes into a cool colorful
cloud of dust how cool is that alright
guys so in conclusion for very little
effort and very little money you can
make yourself some really awesome
exploding targets and the best part is
all your targets are free all you need
to do is find yourself some cheap
plastic water bottles which I’m sure you
have just keep in mind that when these
explode they sound like gunshots in the
neighborhood so just make sure you’re on
good terms with your neighbors well
that’s it for this video guys let me
know what you would use these exploding
targets for in the comments below and
I’ll look for you in the next project
video I’ll talk to you then I think I
got my phone a little bit too close to
that shot that’s a lot of chuck dust
