Introduction: How-To Make Fireworks From Marshmallows, a Pyrotechnic Putty

If you like this Instructable please don't forget to vote for it!!

In this Video I explain how to make a slow burning firework putty using Marshmallows and an oxidizer (Sodium Nitrate in my case...) Potassium Nitrate can also be used but the ratio is 3 parts oxidizer to 2 parts sugar, instead of 2 parts oxidizer to one part sugar like Sodium Nitrate...

What you'll need for this is an oxidizer like Sodium or Potassium Nitrate, Marshmallows and a source of ignition.

I list the formula in the video in case you wish to scale it up or down, which I'll also list here, but note this is the one for sodium Nitrate not Potassium Nitrate...

Sugar content x 2 = NaNO3 Amount or Marshmallow (Weight)/2 = Sugar Content (Roughly) x 2 = NaNO3 (Sodium Nitrate) Amount (Divide by 1.875 instead of 2 if you wish to be more precise) or to keep things simple, Marshmallow (Weight) = NaNO3 Needed (Roughly...)

Remember, though I find this fairly safe if done correctly, I am still not responsible for any damages that might occur if you replicate this experiment, and always make sure to have fire safety equipment nearby... And have fun!!

If you stuffed the coated marshmallow into the bottom of a tube, would it create a more concentrated 'fountain' effect, and if so, how high would the sparks go above the top of the tube? Also, would it ignite with standard fireworks fuse?

Good idea with the marshmallows though, I'll try that

I know how to make fireworks but I don't know how to get SODIUM NITRATE!!!!!!!!!!!

if I add food coloring, will the sparks change to the color of the food coloring

No, the food coloring with do nothing in terms of the color of sparks. You would have to use something like:

-Copper Sulfate (Blue)

-Aluminum Oxide (Yellow)

-Magnesium (White)

-Iron Oxide (Red)

Or possibly combinations of different metals powders, or compounds.

Yes, it is an option. :) Check for commercial holders so you can mount your camera on a tripod. Or, look right here on instructables for how to build your own. :) It will make your presentations much easier to watch.

Alright thanks for the tip.

lebarican (author)2014-03-17

Please invest in a tripod.

I have a phone camera so that is sadly not an option...

I,m sue I have pots of sodium nitrate in my shed, its used as a weed killer on paths and patios, so if I can stop myself eating the mallows, I might give it a try

Make sure it is pure so you don't end up with some nasty side reaction due to miscellaneous chemicals, and remember to be safe.

Other than that Have Fun! :D

you can get a pound of potasium nitrate pretty cheap if you go to the store and get a bottle of stump remover. it comes as a white powder typically in a black bottle that i've seen. just double check the label and make sure that it is in fact pottasium nitrate.

Thanks for the advice, would you by chance know the price range for anyone who is curious..?

Congratulations on being featured!!!

Thank you, I appreciate it.

Aluminium oxide won't react to make sparks - you need to use the powdered metal.

Commercial sparklers use iron, not aluminium. Try repeating this with iron filings or powder.

  • Aluminium or magnesium or magnalium, produce white sparks
  • Iron, produce orange branching sparks
  • Titanium, produce rich white sparks
  • Ferrotitanium, for yellow-gold sparkles\

I actually was using Dark German Aluminium powder I had made, but I think that because it is more of a fuel then and oxidizer that the marshmallow and extra carbon really slowed down the reaction...

Kiteman (author)TrollFaceTheMan2014-03-13

Ah, you kept saying aluminium *oxide* in the video, which is very unreactive.

TrollFaceTheMan (author)Kiteman2014-03-13

Yeah it was my mistake, I am used to saying that for some reason, dark German Alumnium powder is actually fine Aluminium powder cover in charcoal to prevent oxidization...

That is why when I listed the Ingredients for the composition on the video I put "Aluminium Powder" instead of "Aluminium Oxide..."

i keep seeing a lot of experiments using patisum nitrate or other chemicals, where do u get them from?

A lot of time they can be bought under the brand of Certain Stump Removers...

Here is a discussion by a few people who are talking abou this exact thing (

The way I got this one is by making it using Ammonium Nitrate that I got from Instant cold packs and combining it with Lye (

Problem is that way of doing it can be dangerous so I don't recommend it to anyone who does not have a firm understanding of what their doing...

As soon as I heats up outside though I am going to make a video about how to do this via a safer way, which might be a better idea for the backyard enthusiast...

Other than that sometimes they can be bought from certain cooking places, for things like Sodium Nitrate can be added to food to keep things like meat redder longer, and for treatment of corn kernels and such...

Wow, this is so cool!

Thanks I am glade you like it!

Has anyone viewed this yet..? If so please leave a comment... I think my view counter might be messing up... I am getting new Total views... Yet my per Instructables views I think are locked...

It would be appreciated in trying to solve this issue... Thanks!
