three two
one
in three two one they are calling him
the Tony Stark of Kitchener Ontario on
this week's episode of the rocket flight
test we're going to be testing some new
heat shielding to keep my legs safe and
we're going to try and figure out how to
make rockets shoot off at the same time
so or the heat shielding what we've done
is we've actually created a multi-layer
Kevlar blanket with metal plating on the
outside we're hoping that the metal
plating will block the rocket room
enough it's still going to heat up like
crazy
but then the Kevlar welding blanket will
be able to withstand that and not burn
my legs so we're going to do a test to
see if this can actually hold up against
that power now we asked you guys for
some opinions on how to launch multiple
rockets at the same time and a few
people came up with this idea and what
we're trying to do is all these rockets
come with an ejection charge normally
this goes in the yellow end of the
rocket and this will eject the parachute
after the Rockets flown up but what if
we put it in the other end with the
ignition wire that way when the ignition
wire goes the whole thing should ignite
simultaneously because right now it's
actually a pretty big tube in there so
if you stick the ignition wire in there
it might not be touching the wall of the
tube so it might not ignite right away
but we figure if you add some gunpowder
in there it'll work but we're going to
have to test to see all right so we have
our two Rockets here and we have our
ignition wires and some extra gunpowder
never write with Justin Rockets
all right so since we're going to test
simultaneous rocket condition we're also
going to do two heat-resistant shield
tests one is the one I already told you
about the sheet metal and four layers of
Kevlar and the other is four layers of
Kevlar that we're going to get wet and
see what happens
alright let's see how this works we have
a thermal camera behind to see how hot
the back of the material gets and
whether or not we'll burn my legs once
we get that set up it's go time
three two one kids that's why you don't
modify rockets at home
as them as is don't use them at all all
right we're going to do the test again
because we really need to see if these
heat shields are going to work on
modified rocket
all right so that did not work out as
planned number one don't modify model
rockets by putting extra gunpowder in
them that is a bad idea number two our
heat shield still didn't quite work the
plumes ate right through it including
three layers of aluminum sheet metal so
it might be able to protect against a
glancing blow of the rocket but head on
my legs are toast
on the plus side we did obtain
simultaneous ignition and how we did
that was by bending the ignition wire to
make sure to touch the inside of the
rocket that's good but what are we going
to do about my legs how are we going to
do this safely we're going back to the
drawing board try and figure this out
but if you guys have any suggestions
please let us know in the comments
thanks for watching
alright so we've got the rocket loader
done
