hello everyone this is Jeff of Taofledermaus
we are back with the rifle
round chain reaction and if you don't
remember what we did the first time this
is where we use a BB gun to ignite the
primer of the first round and set off a
chain reaction through 11 rifle rounds
- 5.56 rifle rounds be specific on our test
this time we'll be using the
CHRONOS high-speed camera
for this first shot I set the
camera to five thousand frames per
second- this is roughly four times faster
than when we filmed it with our other
cameras and still the event happened
extremely fast - now here I've slowed it
down in the editor about four times and
still it's going very fast we get a
better idea what's going on we could see
the energy wave just screaming down that
tube
ok let's check out the damage
they're all of our charge this is what
our forensic team has found so far is it
out to look at how brass just paddled
out of it
this we think is the very first round
some powder burns and exceeded the
bullet down in the neck might be able to
see all of the powder that blast around
this this this gummy bear was all
completely clear got a huge brasher oh
how is it backwards somehow he had a
bullet seated in his belly barely
touching his belly when we started for
viewer fat shadow by the way who likes
our folding knife component carrying the
columbia river knife and tool in 1614 em
today
shoutout to fetchin now five thousand
frames per second definitely wasn't fast
enough i was trying to find a good
compromise between resolution and frame
rate but let's crank it up to 10,000
frames per second
wow ok let's see what the crows
high-speed camera captured even a 10,000
frames per second this event is
happening extremely fast it looks like
we had a complete chain reaction and I
even solve bullet come out the front of
the gummy bear
let's watch it again hear anything about
the Chronos cameras you can adjust the
resolution both height and by with so I
stole a little bit of the width and
applied it to the height given me a
little taller shot so we can see more
debris flying in the field now we're
going to do one more shot at 22,000
frames per second but in this shot it
actually broke the BB gun now in order
to visualize the speed of the energy
wave that's compared to a 40 Smith &
Wesson bullet that bullet is traveling
about thousand fifty feet per second and
it looks like it's very close to the
same speed as our energy wave and next
we'll compare it to an ak-47 bullet and
you can see that the bullet is much
faster so the energy wave is probably
going about the speed of sound which is
still very fast can actually see the
damage in several different places here
each of those rounds really don't and it
was all nicely painted that into that
and then of course mr. gummy took
another gunshot to the back in this time
but that is it
listen look at me
just a lot of powder it has been
actually dependent just so ready minute
well there's a bullet in there
streetline street yeah somebody was
carried through it like powder injection
which is the name of my retro eighties
band for those you have absolutely no
interest in this video other than want
to know what the music is there you go i
want to thank laura Prepon let me use ur
awesome song for this video
hey when you get there teller tell flare
mail sent you
thanks for watching
