How-To Make a LEGO CANDY Mold


for this project I’m going to show you
how to take homemade treats to the next
level by making your own silicone candy
molds at home to start this project
we’re going to need some Lego I went to
a local store and picked out a bunch of
random pieces for around nine dollars
but the stuff you’ve got lying around
your house will probably work just as
well you’re also going to need a
baseplate for holding the bricks in
place and if you want to copy the style
of my mold then you’ll need four 1 by 1
bricks 9 1 by 2s 15 2 by 2’s 2 1 by 3s 4
2 by 3 S 4 1 by fours and 6 2 by 4
bricks oh yeah and you’re going to need
another 46 2 by 4s you can start
building retaining wall to layers tall
the base plate I got is 32 studs wide by
thirty two studs across and if you start
with one of the two by fours and press
it into place leaving four nubs exposed
on the bottom and three nubs exposed on
the side then everything should come
together perfectly continue laying the
bricks down in a straight line until you
get within four stubs at the end then
turn left you’ll want to keep placing
more bricks until you’ve formed a square
then move up one layer so you can do the
same thing on top but this time
overlapping the bricks they’re staggered
okay our retaining wall is looking
pretty good so let’s move on to filling
the inside with whatever Lego shapes who
want our candies to look like I decided
to keep my mold relatively simple by
arranging the bricks in a way that
optimizes the space and keeps it as user
friendly as possible but you can get
really creative and make your mold any
shape or size you want to whatever you
choose it’s important to make sure
everything is pressed down and compacted
tightly enough so that it minimizes any
gaps between the pieces okay with all
these pieces pressed firmly into place
our Lego candy mold is optimized and
ready to cast with silicone so let’s
move on to doing that next now i cast my
rubber candy molds with a 1 pound kit of
general purpose silicone I got from a
local special-effects supply company if
you don’t have anything like that nearby
or just prefer to use food grade
silicone instead then check the video
description for a link on where you can
find a 2-pound kit for about the same
price opening up the big container you
can see it’s full of a white silicone
goop that has a consistency of wood glue
okay now let’s dump the entire contents
of the second bottle into the mix and be
prepared to work relatively quickly
because once these two substances mixed
together you only get around 30 minutes
of work time before the silicone starts
setting up the second liquid is a
catalyst that will help get the silicone
hardening and it’s bright blue so we can
tell when the
substances are thoroughly mixed together
the idea here is to keep folding the two
parts together until the color is
completely uniform and as soon as it is
I recommend transferring the mix to a
second paper bowl and double checking
that nothing got missed accidentally
alright you can see our mix is blended
really well at this point and if we had
access to a vacuum chamber this would be
the time to suck all the air bubbles out
so we could get the best results but I
don’t have a vacuum chamber and you
probably don’t either
so let’s just skip that part and pour
the silicon goop directly into the
center of our mold instead this stuff is
about the same consistency as processed
honey so as a dribble straight down into
the center of the mold the liquid
naturally begins flowing in to fill all
the spaces below as the silicone slowly
spreads out it gently pushes any air out
of the bottom which is really important
for making the finished product look
nice at this point we’ve got the entire
1-pound mix of silicone poured into the
mold and all that’s left to do is just
give the mold a little wiggle to
encourage any loose air bubbles to rise
to the top then leave it out to set for
about 24 hours when you come back the
next day your silicone will probably
look exactly the same but this time
instead of being sticky and gooey like
it was before you’ll find it feels
strangely hard and rubbery which is
exactly what you want let’s go ahead and
take it out and clean it up a bit start
by gently prying the entire Lego mold
upward and let the rubber release from
the base blade at whatever pace it needs
to when it finally detaches take a look
underneath and you should see all the
LEGO pieces stuck inside and completely
encapsulated by rubber how cool is that
go ahead and break the retaining wall
off from around the sides then pick the
bricks out of the center to reveal your
brand-new candy mold creation now there
are probably some areas where the
silicone seeped in between the cracks a
bit but that’s not a big deal at all
just grab the rubber tags with your
fingers and give them a quick tug to rip
them off it doesn’t take much effort and
after about five minutes of tidying up
you should have yourself a very clean
and professional looking Lego candy mold
these custom candy molds are fun and
rubbery extremely stretchy and very
durable and if you look closely you can
see how the silicone captures every
minut detail perfectly which means your
candies will come out looking exactly
like the real thing the silicone molds
are dishwasher safe and can be cleaned
really easily just by running hot water
over them and not only will they make a
mountain of gummy candies like the ones
I showed you in a previous video but
they’ll cast chocolates as well now some
people might wonder if it’s okay to use
general-purpose silicone for casting
candies
with the stuff that I’m using it’s just
fine because casting silicone is inert
and impressively nonreactive
you could probably eat pieces of the
mold itself and be just fine but if you
have any concerns at all just make yours
with food grade silicone instead I found
this two-pound kit online for about the
same price and I’ll put a link in the
description to where you can find it one
pound of silicone makes one Lego mold
like this so a two-pound kit will make
two of them but if you want to try
playing around and experimenting a bit
you can cast just about anything you can
think of I made a mini Lego mold for my
kids to play with and another mold for
casting chocolate bars which I’ll show
you how to make in another project video
well now you know how to use Lego bricks
and a two-part silicone mix to create
custom silicone candy molds at home
that’s it for now if you liked this
project perhaps you’ll like some of my
others check them out at the king of
random calm
