okay what is it you wanted to show me
let me show you how someone can
unlock your phone using your fingerprint
without even knowing
how are you gonna do that uh i'm gonna
make a replica of your fingerprint of
your phone yeah i do
watch this here it is um this is your
phone right
yeah so look if i try to use my thumb
print obviously
not gonna work right right try yours
okay
all right so uh here we go all right so
say you left your phone laying around
right mm-hmm
what you want to do is uh get a balloon
put some water in the bottom of it
blow it up the water is what's going to
keep the balloon from breaking
all right so looks so cool yeah
now you will start to see it kind of
smoke all right i hold this here for
about 15 seconds you'll see the smoke
start to come out you see that oh yeah
you don't want to do it too much because
this thing could pop at some point but
basically this gives us a lot of soot
on the bottom of this balloon a lot of
soon you see that yeah now take a brush
and this soot is what we're going to use
to cover the brush with
which will be very important for making
a copy
of your fingerprint off of your phone
you want to get it nice and sorted up
you see all that stuff on there falling
off yeah it's kind of satisfying
sometimes it's right now watch it so
with another brush full of soot
we have your iphone now your thumb was
on this last so your fingerprint is the
last one on here
which is crucial because watches you
want to just ever so gently
just start to just very gently just kind
of dab where the thumbprint was
just ever so gently you see that you can
see it coming through
i know but watch covered all the way
that's nuts that's your fingerprint all
right now watch now that we have your
fingerprint let's dust it out and watch
it take a piece of tape
i prefer like a thin uh this kind of
thin scotch tape or whatever
you're gonna take it and that oops
actually i already messed up because you
see every time you touch the tape
you're gonna leave a fingerprint right
see that every time you touch it and i
have one in the middle here
which you do not want okay you cannot
have it needs to be completely
uh clean tape in the middle so let me
try another one it's probably easier if
you just
pull a big old piece out that is much
longer than you need
right so now i can touch the edges of
this but the middle stays completely
clean see that yeah
edges are fine to touch but the middle
has to stay completely clean so watch
we take uh your fingerprint this is just
the same
it's the same way that the you know the
detectors do it a crime scene i'm going
to just put it right
over like that
i want to make sure there's no air
bubbles special actually work yeah well
we'll see yeah it should let's
watch okay rub it with the brush a
little bit just kind of just
just making sure you get a really good
lip on the print okay because in a
moment i'm peel this thing off
you want to make sure it gets all of
this soot with all your fingerprint
indentation on it all right
it's also helpful that i have these
little things on the side just makes it
easy to grab off
all right and then this will be really
helpful for
later when we come to replace it
watch i'm just going to draw like a
little box
around this and this is just so you know
exactly where to put it
and you'll see yeah watch so
you want to do this part extremely
gently this is a very
important step watch you'll see okay
okay you can wipe this off now
wipe this off and now we should be left
check it out with that is your
fingerprint
right there yeah yeah okay so
now i have your fingerprint this is
where it gets really this is the moment
all right
you can store this thing uh just make
sure that this center part has to remain
undamaged okay you cannot damage that
print right there that's the
that's the that's the print all right so
you store it somewhere if you're gonna
store it somewhere you have to just kind
of stick it
on the side of the thing but you know
leave it dangling off make sure that you
know
that the uh the print stays on damage so
there's your print you can see that get
a
shot of that so right there's your print
all right yeah
now whenever it comes time where you
want to use this thing
uh you're basically gonna line it up the
same way it did once again this is all
this is blank this could be weeks months
i mean this this print can be unaffected
for a long time
and when you're ready to reuse it and
unlock the person's phone let's see if
this works
i'm going to line it up perfectly boom
should be close enough and then let's
once again we want to get the air
bubbles out of this thing
so we're going to just ever so gently
rub that all over it all right
and i think we're ready okay so let's
see if it worked
all right we have the soot on here and
if this works properly
wait let's see i really want to make
sure it's stuck because you may only get
one shot of this right i mean every time
you remove the tape
it will damage this even more so right
you know the first time you do this you
do want to make sure you get a really
good
you know adhesive um you know
and centered stick to it and then let's
see if it works ready
oh my gosh
