The LEGO Vacuum


in this video we’re gonna be showing you
how to take this Lego brick container
and transform it into a vacuum that can
suck up and then store all of your Lego
brick pieces to get started we’re going
to need some kind of plastic box a
vacuum cleaner and some spare vacuum
hose I happen to have one of these
actual Lego boxes that’s shaped like a
giant Lego brick but you don’t have to
use one of these if you just have a
clear plastic shoebox sized container
that will work just fine we’re also
going to need an exacto knife a glue gun
some type of mesh cloth or fabric and
all the ingredients that we use to make
our proto potty that’s type 1 silicone
some food coloring and some cornstarch
here’s what we’ve got in mind we’ll cut
two holes into the lid one for the hose
going in and one for the hose going out
a proto putty seal around the whole lid
will prevent any air from leaking and a
mesh filter on one side will prevent any
LEGO pieces from accidentally getting
sucked up into the vacuum cleaner first
we need to tape the lid of our container
and add some holes if you’re using these
nice Lego containers I like to put them
right here on these bumps because it
just keeps the aesthetic fusing a
container with a more flat lid you just
cut right into the flat surface we’re
going to want one hole on one side where
our vacuum cleaner hose will go in and
another hole on the other side where our
additional hose will come out now I’m in
a workshop in here we have a shop vacuum
but if you want to just do this at home
with your home vacuum that will work
just fine as long as you have a hose
that can be pulled out one quick note
about using a home vacuum if you have
the type of vacuum that has turning
bristles and you take the hose out you
do want to make sure that those bristles
aren’t still rotating in contact with a
carpet because after a couple of minutes
the friction can begin to melt or burn
some types of carpet so if you are doing
this at the home back you may want to
take your vacuum cleaner and tip it on
its back so the bristles aren’t gonna
burn anything now we want to make a hole
in one side that’s just the same size as
this adaptor and a hole on the other
side that’s the size of our vacuum hose
I picked this vacuum hose up at a store
that just specializes in all sorts of
different types of hose it was pretty
convenient if you don’t have one of
those near you there are a few other
options there are some kinds of pool and
drainage hose that are about the same
size and this is the
one in a quarter inch diameter or you
might be able to find an old vacuum that
doesn’t work anymore and take the hose
off of there or if you have a vacuum
repair shop they might have some broken
vacuums and be able to sell you one of
the hoses let’s take our hose place it
right where we want our hole to be and
then trace around it with a permanent
marker and let’s do the same thing with
our other hose these hoses are very
similar in size but not quite identical
if you happen to have a hole saw that is
exactly the same size as one of your
hose connections you can probably use
that and it should work just fine both
of my hose connections ended up being
not quite the same size as any of the
hole saws so we’re just gonna use an
I suspect I’m still gonna need a little
additional trimming before this fits
quite right yeah it’s still just a
little tight but I just need to trim
down the plastic a bit more there we go
our hose now fits in and it is nice and
snug it holds itself in place you can
see that the lid is just really well
attached but we can pop it out when we
need to
that’s one cut now let’s cut the other
[Music]
now in this box specifically the corners
have these support pieces that I think
help keep the box in shape and help it
stay on the lid while those may increase
the structural integrity and be a good
thing most of time they can kind of get
in the way for us so what we need to do
is trim away some of these little
plastic tabs we now have our hose intake
and our hose out take is that right
mm hose in and hose out so what we need
to do is make it so this lid fits
perfectly snugly onto our box as it is
we can attach the lid and it may stay on
but there’s a lot of space around the
sides air is going to be able to get in
through all of the gaps and we don’t
want that we want all of the suction to
come out of the front of the hose to
what we need to do is make a proto putty
seal that goes all the way around so
when we have the vacuum turned on all
[Music]
also this particular container has two
small holes at the bottom and we want to
plug those up and we’ll just use a
little bit of our pro buddy for that as
well all right our portal putty is
starting to set but it’s not there yet
you can see we’ve still got lots of
squishiness to it and that’s exactly
what we want while it’s still squishy
we need to take our lid and press it
down over the box so it forms a nice
tight seal and the goal is not to make
it so the lid can’t come on and off
because of course we do still want to be
able to remove it but the goal is so
that when there is suction in the box it
just pulls itself nice and closed
instead of having lots of air rushing
all the gaps one more thing that you can
do if you cut your holes and you find
that the hose is a little more loose
than you’d like you can use some extra
proto putty to make a seal that goes
around the hole to make sure your hose
connection is nice and snug depending on
how well you cut your holes you may need
to do this on one side both sides or
neither side now that we’ve got
everything formed it’s time to just let
our proto Pierre for a few minutes until
it’s nice and rigid our proto potty is
nice and cured so now we can remove our
hose and we can remove the whole lid if
you’ve made the proto putty correctly
with all the cornstarch mixed in it
shouldn’t stick too much it should just
be able to slide on and off while
holding itself nicely in place one of
the nicest things about the proto putty
that we use for the seal is that it’s
designed not to stick to things too much
by adding all of that cornstarch that’s
really nice because it means we’re able
to fit it on the lid and then take the
lid off and on but one of the downsides
is that it is possible that your seal
will just be kind of loose on your box
if you want to make it a little bit more
permanent you can take a bead of the
caulking without any food coloring or
cornstarch in it and that should do a
pretty good job of bonding the silicone
seal to the plastic of the box this
stuff is sticky it’s only not sticky
because we added so much cornstarch now
we don’t want any little Lego pieces to
get sucked up into the actual vacuum
cleaner so what we want to do is add a
filter onto one side and I’ve got a
little piece of screen mesh
you could also use any sort of cloth
with large mesh like a tool or some kind
of netting this is just what I have
available so this is what I’m gonna use
this little flange seems like it will
get in the way so let’s just try and
trim that off with our exacto knife now
I’ve got a hot glue gun and our mesh
let’s just cut this to size and then
glue it right over that hole it should
still let air flow through it really
nicely it’s not gonna slow down the
vacuum power at all but it’s just gonna
make sure that none of our LEGO pieces
end up in our vacuum cleaner that’s
pretty hard to see what it did draw on
[Music]
that’ll do it we have a mesh covered
hole in one side and a non mesh covered
hole on the other side we should be able
to pop this lid on attach our vacuum
hoses and start sucking up Lego directly
aha
box full of LEGO pieces very cool that
worked great and you can see a little
bit of fuzz did get sucked up and pulled
up against our little filter here so
that may be something that is worth
cleaning every once in a while really
small dust should probably still get
pulled right through that filter the
bigger dust will just get caught up
against it but that worked great
it even pulled out some of these longer
skinny pieces they didn’t like to go
very well but when you sucked them up
with other pieces it all sort of
traveled through the hose even some
pieces that I thought seemed kind of
large like this little window frame
piece it does fit in the tube but not
super easily but it still managed to
travel up through there quite nicely
well this works great and I did want to
do one thing just to show it off even a
little bit more I have a second Lego box
that I’ve modified by adding a clear
window onto the front of it
now we should be able to see the LEGO
pieces after they’ve traveled through
the vacuum tube landed in our box and we
[Applause]
[Music]
[Applause]
that’s awesome just flies in there all
over the place it’s pretty neat now like
I said it’s not necessary to put the
clear window on the side of your box
that’s just something that lets us see
what’s going on as the luego flies in
there and I think it looks pretty cool
overall though I would just go with the
normal box no window added because you
know that’s gonna work just as well and
saves you some time and effort guys this
has been awesome but the fun doesn’t
have to end this little box up at the
top will transport you directly to our
last video and you should check that out
the box at the bottom will show you at
YouTube thinks you need to be watching
now and this bomb here in the middle
will subscribe you to the channel so you
never miss out on a video don’t forget
to ring that Bell and we will see you in the next one talk to you then
