Jamie Hyneman Answers: What's One Myth You've Always Wanted to Test? - YouTube

i'm jamie hyneman on reddit ama I am a
whatever the question I'm answering is
[10]
one from ho4 X what's one myth you've
always wanted to test but couldn't due
[15]
to financial slash illegals that slash
safety etc reasons there's this one
[21]
thing that for some reason I can't talk
anybody else into getting interested in
[26]
but me and it's based on the on a story
that Cary Grant or did a while ago where
[32]
they had a baseball or a guy on a train
who's a professional pitcher rather has
[38]
a baseball and he throws it backwards in
the direction opposite to which the
[44]
train is going and he throws it at
exactly the same speed that the train is
[49]
traveling so to a person on the side the
suppose admit is the ball would drop
[54]
straight out of the air and just sit
there on the ground and so that's all
[59]
well and good they tested it and it and
it's possible and everything but the
[63]
thing is I want to be the baseball and
my idea is that we would set up some
[69]
sort of a low trailer sort of a thing
and put it on a truck or trailer behind
[75]
a truck and we would put a backward
facing slingshot like you know out of
[81]
surgical rubber tubing or bungee cords
and and I would get into a sort of a pod
[88]
or maybe you can just sit on a chair or
something and get fired backwards at the
[93]
same rate that the truck is going
forward now for some reason insurance
[99]
won't let me do this and you know my my
problem with that and the reason that I
[106]
should be able to do it is that you know
we can deal with these things
[111]
incrementally like for example would you
let me do it at five miles an hour of
[115]
course you would you probably let me do
it at ten miles an hour and if it's safe
[121]
at ten miles an hour and there's
absolutely no problem why not you know
[125]
fifteen or twenty or fifty you work your
way up to it and of course you can be in
[131]
some sort of like
if there's any kind of question you can
[134]
have protection like a bee in a cage or
a pod that that you know won't that
[140]
nothing bad can happen and and or we can
also test Buster before doing it now the
[146]
thing that they're worried about and
this is where it got interesting for me
[150]
is that I started to break it down and
it's not the fall it's the potential
[158]
problem that you'll have if there's a
mismatch in speed if the bungee cord
[162]
doesn't shoot you backwards at exactly
the same speed that the truck is going
[166]
forward and and so the you know you can
set up this slingshot thing so it's
[173]
right above the ground so it's not the
fall it's about that mismatch and what
[176]
happens with myth mismatch as I started
to think about it is mainly friction
[182]
because once friction starts to come
into the equation the thing that touches
[188]
the ground first is going to catch while
the rest of you wants to keep going and
[192]
so you start to tumble and if all this
is happening really fast then you tumble
[197]
really fast and you break your bones in
your head or whatever but assuming that
[201]
we've not got any kind of like curbs or
obstacles like we do it out on there a
[206]
runway or something like that if you
don't have any friction you've not got
[212]
any kind of problem with tumbling you're
just going to slide that's what they
[215]
have that's why they have a motorcycle
gear that is armored doing with plastic
[220]
or leather and if the motorcycle falls
down as long as you don't hit a curb or
[224]
something you're just going to slide
you're going to be fine and and so I you
[231]
know reasoned that the other way to do
it or of course is like there's all
[235]
sorts of different ways of removing
friction then that could be lots of
[239]
lubrication which would be quite funny
and make for a good episode and I don't
[244]
know why the producers don't think that
that's fun but the other thing one could
[249]
do is is have something that is
something like a like a ski or a shallow
[256]
metal pan and so you get you know fired
to speed if there's a Mitch Matt and
[260]
this mismatch of these philosophies
you're just going to the pan will send
[265]
out some
ARC's or something or maybe it's a
[267]
plastic thing you're just going to slide
and so the end result of all this
[272]
testing would be that in theory you
could have a bus that could go buy a bus
[277]
stop and deliver passengers without even
slowing down which you know may not be
[283]
something that gets picked up by mass
transit I'm sure in the near future but
[289]
it would be fun to try it
