In this Instructable, I'm going to show you how to make gummy candies.

I made a silicone candy mold using Lego bricks. You don't need to make a custom mold. There are many commercially available silicone molds, or you could just skip the mold completely, and cut them with cookie cutters, a knife, or even scissors.


First I'll tell you how to make the candy.

I'll explain in detail how I made the mold in step 4. It really is very easy. User Gabebillings made the mold and documented the process in photos. See the first comment under step 4 to read his experience and see his photos.

User ibeschieru made a "making of" video showing his kids creating Lego shaped gummy candies!

I bought the Food Grade Silicone from Douglas & Sturgess. They are a great San Francisco store that sells artists materials, mostly for sculpture and casting. They have some great info on their site.

If you have kiddos that might mistake real bricks for the candy, you should consider whether it is safe to make these for them.

Vegan option There is another kind of jelly candy called gellies or jellies. Those are made with Pectin. It's a different recipe entirely. I don't know how well they would mold though.

Here is a Pectin Fruit Jelly Instructable. I haven't tested it in the mold but it seems like it should work. Pates de Fruit

Here is a video based on this instructable. Hope everyone enjoys it.

Awesome work. Thanks
Great Instructable!  I purchased my silicone from - I used their CopyFlex.  The only two reasons I used theirs is because the mix is a 1-to-1 ratio so I don't have to worry about how precise I am with it and they are in Cincinnati, so shipping was substantially cheaper for me here in the U.S. midwest.  1 lb. was perfect for the size of the mold I made.  I first used a little paintbrush to paint the silicone onto the lego pieces just to make sure that there was no air bubbles around the pieces themselves.  I tried to make a gummy lego dude, which actually worked better than I thought it would!  But I had to do some trimming with a knife to cut him free from the silicone and give access to free the gummy from the silicone later, but it worked pretty well.

The recipe you give for the gummies was perfect.  I tried yours and another I found online and yours worked much better.  Had a lot of trouble getting them clear though.  They ended up pretty cloudy.  Added a few pictures.  Thanks again!  Great instructable!

That is so incredibly awesome. People ask about the lego guy a lot.

Here is how I make them perfectly clear:
I crush the vitamin c, dissolve it in water, let it drip through a coffee filter, then use the resulting clear liquid to sour the candies.

If it isn't the vitamin c making them cloudy, then it is probably because you are stirring too vigorously. You have to be very careful not to push air down into the syrup when stirring. Don't ever stir the foam back into the candy.

The other cloudy problem is from not letting it melt long enough. Just let it sit and mello in the boiler. The longer it stays, the more clear liquid gathers on the bottom.
How did that copyflex work? is it worth the 22 bucks?
I thought it worked great for this.  It was easy to mix and pretty quick to set up.  I'd recommend it.
Thanks! I saw some other kinds but this looked the best and easiest to use. I'll have to try it!
Wow, I like the gummi man :)
I had seen that website before but unfortunately the postage for me was $36 for 1lb, still haven't found anywhere else that sells it and I'm desperate to make these. I tried emailing Douglas and Sturgess about postage but they've not bothered to reply :(

If anyone knows other places that sell the silicone please let me know.
SFHandyman (author)  Badgerdan5 years ago
The price at Douglas and Sturgess would be about the same.

Sorry they haven't replied to your question. I think they are set up more as a business to business supplier, but they do have 1 retail store and it is here in San Francisco. I think most of the materials they ship out of their warehouse and over the website are larger industrial quantities. That isn't to say they should neglect you. I'm sorry that happened.

The guys in the store are Awesome. I'm sure it was just an oversight. (I thought I'd replied to you days ago but just realized it hadn't posted!)

This is so awesome. I saw the comment on my phone and it didn't reveal there were PHOTOS. I love it.

The lego man is great!

Thank you for your tips and sharing the photos.

I added Step 5 that details the process I came up with that makes almost perfectly clear candies.

Just was at and looks like their "Food Grade Silicone, 1 lb." has the purchase number "Code: MC-1287".

Also, glad to know someone else out there calls them "kitchen scissors" too!

SFHandyman (author)  ceafin4 years ago
hahaha I thought Kitchen Scissors was universal. I have sewing scissors too. Paper dulls scissors, so you never ever cut paper with your fabric scissors. You can cut hair with your fabric scissors though.

Thanks for the code update. It has changed a few times.

Just to let you know, douglas and sturgess have the silicone on their wbsite now. here is the link.
SFHandyman (author)  kcls4 years ago
Here are a few pictures from my moldmaking process.  The first is the Lego grid I built.  As mentioned on the main comment page I worked the volume out by counting bricks and figuring out the volume.  A 1 lb. container of silicone filled it perfectly.  Incidentally when I mixed it by weight, I had some of the smaller container left over, probably because I didn't scrape out the big container well enough.  The next two pics are just after combining the two parts, and then what it looks like mixed together.  I didn't use anything high tech for this, just a plastic knife.  There were a fair amount of bubbles in the mix, but I ignored them.  When I started pouring the mold, it wasn't moving exactly like I wanted it to.  I did a fair amount of nudging it into place with the knife.  As slow as it is to move, though, it will indeed fill all the voids and level out if you're patient.  You can see some of the larger bubbles in the last picture.  I obsessed over the bubbles, but all the big ones worked themselves out.  There will be some microscopic ones left all over the bottom, but they don't matter.  All of this was done with no prior experience or knowledge except for SFHandyman's instructions, and the mold turned out great.  If you're thinking about trying this instructable out, I urge you to do so.  It's a lot of fun.

So, so, so, great. Thanks for superb instructions.
SFHandyman (author)  kansas6 years ago
Wow, wow, wow, Thank you.
I have no other reason to get a metric scale. Have you ever made an extra silicone mold and sold them? I know it sounds lazy, trust I'm not that way I just can't justify spending even $5 for a single project then never using it again. I would like to make Lego gummies and ice cubes just for fun.

Lego makes some, actually. The brick-shaped ones aren't always available, but the minifigure-shaped ones tend to be. Plus, if you live near a Lego store, some of them have the brick-shaped molds in stock.

Wouldn't Myth Busters make their Ballistics Gel out of Knox like everyone else?
SFHandyman (author)  ronmaggi5 years ago
I'm pretty sure it's a special mix.
no they said on their show once that they used unflavored gelatin

Knox is a brand of unflavored gelatin. ;) I use it for this stuff all the time.

They likely use a product that when set, has the density and mass of a human body.

If you live near a Lego store, you can make Lego gummy without having to make your own mold. Their brick- and minifigure-shaped ice cube trays make actual-sized Lego treats for a lot less money than buying the silicone.

But then you don't get to make your own mold yourself. So it's a tradeoff.

(semi)pro tip for crushing things when you don't have a mortar & pestle: double-bag things to be crushed with ziploc plastic bags. Attack with rolling pin.

 It would be awesome to make some nes 8-bit sprite molds

might do that :D

SFHandyman (author)  ZEROTB4 years ago
Whoosh. That went right over my head. "nes 8-bit sprite"?

Go for it though. I don't know what they are but be creative and have fun.

Making it as I speak, didnt have any unflavored jello though, so I used 1 box of sugar free (my grandmother is diabetic) mixed fruit jello and about 3/4 a box of pectic (she also likes to can and make preserves and is teaching me) the syrup is very tart but I think with sugared jello they'd make great semis sweet candies :D I'll upload a instructable if it works

typo: pectin

Amazing! Would love to try making it.
This is amazing. You are amazing.
Xandergust2 years ago
I am really excited to try this! Thanks for the post! How long do these stay "fresh"? I want to make these for a party and would love to do this ahead of time, but there's nothing worse than a stale gummy.

What happens if you allow the liquid to cool to lukewarm before pouring into molds?
