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 $9, but the stuff you’ve got lying around your house will
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 4 1×1 bricks (maroon), 9 1x2s (blue), 15 2x2s (green), 2 1x3s (grey), 4 2x4s (yellow),
4 1x4s (black), and 6 2×4 bricks. Oh yeah, and you’re going to need another
46 2x4s so you can start building a retaining wall 2 layers tall. The baseplate I got is 32 studs wide by 32
studs across, and if you start with one of the 2x4s and press it into place leaving 4
nubs exposed on the bottom and 3 nubs exposed on the side, then everything else should come
together perfectly. Continue laying the big bricks down in a straight
line until you get within 4 stubs of 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 so they’re staggered. Ok our retaining wall is looking pretty good,
so let’s move on to filling the inside with whatever LEGO shapes we 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. Ok with all these pieces pressed firmly into
place our LEGO candy mold is optimized and ready to be cast with silicone, so let’s
move on to doing that next. Now I cast my rubber candy molds with a 1lb
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 2lb kit for about the same price. Opening up the big container you can see it’s
full of a white silicone goop, that has the consistency of wood glue. Ok, 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 mix together, you only get around 30 minutes of work time before the
silicone starts setting up. This second liquid is a catalyst that’ll
help get the silicone hardening, and it’s bright blue so we can tell when the two substances
are thoroughly mixed together. The idea here is to to keep folding the 2
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 silicone goop directly
into the center of our mold instead. This stuff is about the same consistency as
processed honey, so as it dribbles 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 one-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 baseplate 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 will probably be 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 rip them off. It doesn’t take much effort, and after about
5 minutes of tidying up, you should have yourself a very clean, and very 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 minute 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 ok
to use general purpose silicone for casting candies, and with the stuff I’m using it’s
just fine because casting silicone is inert and impressively non-reactive. 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 2lb 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 custom 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 2 part silicone mix, to create custom silicone candy molds at home. That’s it for now. If you liked this project,
