Practice English Speaking&Listening with: How-To Make a LEGO CANDY Mold

Difficulty: 0

For this project Im 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 were 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

youve got lying around your house will work just as well.

Youre also going to need a baseplate for holding the bricks in place, and if you want

to copy the style of my mold, then youll need 4 1x1 bricks (maroon), 9 1x2s (blue),

15 2x2s (green), 2 1x3s (grey), 4 2x4s (yellow), 4 1x4s (black), and 6 2x4 bricks.

Oh yeah, and youre 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.

Youll want to keep placing more bricks until youve formed a square, then move

up one layer so you can do the same thing on top, but this time, overlapping the bricks so theyre staggered.

Ok our retaining wall is looking pretty good, so lets 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 its 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 lets 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 dont 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 lets 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 thatll help get the silicone hardening, and its

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 dont have a vacuum chamber and you probably dont either, so lets 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 weve got the entire one-pound mix of silicone poured into the mold, and

all thats 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, youll find it feels strangely

hard and rubbery, which is exactly what you want.

Lets 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 thats not a big deal at all.

Just grab the rubber tags with your fingers and give them a quick tug rip them off.

It doesnt 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 theyll cast chocolates as well.

Now some people might wonder if its ok to use general purpose silicone for casting

candies, and with the stuff Im using its 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 withfood gradesilicone instead.

I found this 2lb kit online for about the same price, and Ill 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 Ill 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.

Thats it for now. If you liked this project, perhaps youll like some of my others.
