Introduction: Homemade Fizzy Pop Rocks Candy!!!

Picture of Homemade Fizzy Pop Rocks Candy!!!

I love Pop Rocks! 
So a homemade variety sounded great!

This recipe makes a tart and fizzy treat...not the same as the store bought stuff...
but really fun to make with the kids! 

Step 1: Gather the Supplies!

Picture of Gather the Supplies!

Here's what you'll need:
(makes quite a bit...might just want to 1/2 it)

2 cups sugar
1/2 cup light corn syrup
1/4 cup water

1 teaspoon flavoring extract, flavor of your choice
3-4 drops food coloring, color of your choice
1/4 cup citric acid
1 teaspoon baking soda

1 additional teaspoon of citric acid

Pinch of cornstarch, for dusting...
Lightly dust baking sheet with cornstarch.

Step 2: Saucepan...

In a saucepan, combine the sugar, corn syrup, and water.
Cook the mixture until it reaches 300 degrees (hard crack)

I use a candy thermometer.

Step 3: Add the Fun, Flavor and Fizz!!!

Picture of Add the Fun, Flavor and Fizz!!!

Remove from heat

add the baking soda
¼ cup of the citric acid
extract (we used one dram of strawberry)
food coloring
(we only did 2 drops and it pastels the
color so I'd go with 3-4 drops)

Step 4: Mix and Pour...

Stir to combine.
Pour the mixture out onto the baking sheet...
sprinkle with the teaspoon of citric acid.

Step 5: Break It Up...

Cool completely, about 30 minutes.
Break the candy into pieces.
I just used a butter knife...
You can break it up into small pieces,
then put some in a plastic bag and hammer them
into little pebble pieces!

Store in Ziploc bags.

Step 6: Try It Out!

Picture of Try It Out!

The candy is filled with holes from the baking soda!
This is supposed to be the magic coupled with
citric acid to get that pop effect!

They are really crystally and cool looking!

No, not like store bought Pop Rocks...
That are sweet and explode in your mouth...

It was sort of fizzy and sometimes bubbly in
your mouth...but slightly sour!

Not too sour for me or my daughter...
(who's nick-name involves the word 'lemons'...because she loves lemons)

Was it fun to make and eat?
YES!  And it's super fun to watch them eat it!

Step 7: And Take Pictures!

Picture of And Take Pictures!

And it makes a lot!!!
(maybe if you try it--give some to friends or only make 1/2)

We ate it until our mouths were sore...all in the name of science!

Yes, the food coloring is optional.

SamuelN11 (author)2016-03-06

Is the food coloring optional?

Badenpowell (author)2016-03-01

In the UK it is called Honeycombe or Hokeypokey.

Looks Great,

by the way, ever try Molasses Sea-foam Candy?

Katie belle (author)2016-03-01

Pure health food. Good job!

...also this has nothing to do with real pop rocks as the title baits.

Citric acid is generally available in most grocery stores in the Canning supplies section. Also available from Amazon.

Where can I find the Cotric Acid?

spark master (author)2016-03-01

no popping, ...fizz stone then!!

tedbear2 (author)2013-04-15

Also, is there a neutral citric acid I can use or is bottled lemon juice okay?

DavidM564 (author)tedbear22016-02-19

Lemon juice contains both citric and ascorbic acids. It would work very well, but you would need to titrate it to find out how much baking soda to add. I would take about 2 tablespoons of lemon juice and then add a small controlled amount of baking soda (say, an 1/8 of a teaspoon) into the juice until it stops fizzing. That will balance the reaction and make sure that you don't add too much of either ingredient. You might actually want there to be some left over acid for taste, so just make sure you don't add more baking soda (in proportion) than you figured out with your titration. Good luck. :)

DavidM564 (author)DavidM5642016-02-19

The main goal of this is to make sure that you use enough baking soda to get the maximum fizzy reaction, but that all of the baking soda is consumed so that you can't taste it in the final product.

Arcan3 (author)tedbear22013-04-17

yes there is, i think (dont quote me on it) unflavored vitamin C is mostly citric acid.

deh260583 (author)Arcan32013-04-23

vitamin C is ascorbic acid, not citric acid. You can use vit C and any other acidic material. the fizz come from the reaction between baking soda (base) with acid.

Made this with lemon juice amd it was AMAZING

ElisaV (author)2015-07-05

hiiii, i made it and it has been almolst 5 hours and it still has not hardened even a bit.

Benchkey (author)ElisaV2015-09-06

You must get the mixture to 300f which is the Hard Crack stage, it hardens within minutes. Something not mentioned is when in the cooking pot, be sure to wipe down the inside of the pot with a brush wet with water. Don't get the brush in the mixture. Washing down the sides gets any sugar crystals into the boiling mix. If you don't and you get sugar crystals in the final candy it will crystallize and be ruined.

AmeliaP4 (author)2015-08-29

I know I'm late to the party ;) but any ideas on why mine is not fizzy? Could my baking soda be too old?

pitothepowerof3 (author)2015-05-05

Would it be possible to make this with a pop flavour? For instance, orange soda, or something that already has the citric acid in it.

tedbear2 (author)2013-04-15

I really want to make this but can you tell me how many millilitres are in a cup?

aeboi80 (author)tedbear22013-10-03

A little know trick to most is just use Google :-) If you Google 1 cup to ml it will tell you. The same for 22C to F Google has lots of built in calculations it can do for you.

doodlecraft (author)tedbear22013-04-15

I am sure that there's a conversion calculator on the internet somewhere...figure it out and try it! :)

tedbear2 (author)2013-04-15

Just began to make this. Looks delicious so far :)

chickflix (author)2013-04-13

This reminds me of the Pop Rocks 'ible I made for the candy contest a couple years ago.... Nice job

doodlecraft (author)chickflix2013-04-13

Oh, no way! I didn't even check! :) Great job to you!

chickflix (author)doodlecraft2013-04-13

Yup, I made it for the last candy contest.

perfo (author)2013-04-12

If you want to be extra creative and a bit inventive. Then whilst this is still very liquid put it in a container that can be pressurised and pressurise it with C02. try and agitate it as much as possible whilst under pressure and let it cool without depressurising. The little trapped bubbles will now be at a higher than atmospheric pressure and will give you the popping in your mouth sensation.

Remember to brush your teeth after this! Citric acid is a great cavity mining tool.

ldeese1 (author)2013-04-11

I was wondering, could you substitute something like some unsweetened powdered drink mix for the flavoring extract and food coloring or would that change the recipe too much? This looks like a fun Instructable to do!

doodlecraft (author)ldeese12013-04-11

Great idea, your guess is as good as mine! Try it and let us know! :)

xLaurieClarkex (author)2013-04-09

Sounds like this makes something similar to Fizzies instant "carbonated" drink tablets -- but these might be better! I'm gonna make some pdq :-) thanks for the Instructable! I voted for ya :-) #sugardome

Penolopy Bulnick (author)2013-04-09

Yummers! I would love to try to make this!
