For this project I used items from around the house to create a pyrotechnic time-delay. Here's how to make a simple form of a slow burning fuse, because when experimenting with homemade pyrotechnics, you don't want to be too close if your composition explodes.

Some quick links to a few of the materials I used:

[✓] Spectricide stump remover: amzn.to/2cXdmMn
[✓] Sugar: amzn.to/2ctLMFm
[✓] Cookie Tray: amzn.to/2c8YNFp
[✓] Fire Extinguisher: amzn.to/2cd14Ox

Project Inspired By:

   • Kno3 and Sugar Paper Fuse  

Project History & More Info:

Similar to the recipes I tried for rocket fuel and smoke flares in previous videos, I'm using a 60/40 mix of KNO3 and white table sugar by weight. This time I'm making a 60 gram batch, adding it to boiling water, and stirring it in until it all dissolves.

Fuses were homemade by soaking 12 feet of 100% cotton yarn in the solution as the rest of the water evaporated out, then placed on a cookie sheet and baked in an oven at 300ºF for 20 minutes.

These types of devices may not be legal to make or use in your area, so check local laws before attempting to duplicate this project, and as always, be safe and aware of your environment before igniting anything flammable!

    This guy is still alive in so many hearts. Had a blast last year with my kids on the 4th cause of him. Doing the same this year, thank you!!

  • Husband: Mmm, that smells great honey! What are you baking? Wife: Oh, you know. Fuses. 
  • @TheKingofRandom
    I'm glad you had some success with it. Thanks for joining my channel and for sharing your experience. I haven't had any luck with the waterproof fuse, but will keep trying ideas as they come along. :)
  • @SIowpoke
    I want to see cashier's face when a group of boys buys a lot of stump removers...
  • @MulderXfile
    most pharmacies sell pottasium nitrate. just ask for diy bomb isle.
  • @TheKingofRandom
    Me too. I'm very happy with it, and I take them out at night and use them like sparklers for the kids. Super cheap and easy to make.
  • @TheKingofRandom
    Thanks! Sometimes pushing the boundaries is the only way to discover what the boundaries really are. I'm glad you like to see the results. Plus, I feel they help support my conclusions.
  • Thanks man, was needing this for making one of your rockets (kitty litter rocket) and couldn't think of a making a fuse. You may be gone, but you're still a big help to everyone.
  • "Mum, do we have Potassium Nitrate?" "yes sweety theres some in the pantry"
  • @TheKingofRandom
    Wishing you a speedy recovery, and closer attention to detail in future projects :)
  • @TheKingofRandom
    Yes. I did a test where I sealed a batch in an air-tight bag, and left a few outside the bag. After a month, the fuses exposed to the air would hardly light, and didn't work very well. They can be made useful again by putting back in the oven at about 300-330F for 20 minutes. The ones sealed in the bag were nearly as good as they were when I made them a month prior. Thanks for asking!
  • @Orc-icide
    I just made some of this! Its hard to find Stump Killer (KNO3) in NYC but my dad got us some for christmas and we made some today. INCREDIBLY EASY TO MAKE. READY SAME DAY. Me and my dad soaked up the rest of it in a flat paper towel, took it outside and LET IT BURN!!!! IT WAS THE MOST AMAZING FATHER & SON TIME I HAVE EVER HAD EVER !!!! Thank you so much Grant Thompson. I will try to get a donation to you as soon as I figure out how!!! lol
  • @johnbacon1340
    Worked perfectly! Just follow the instructions exactly. Was a little nervous at first but worked very well. Thank you for the upload
  • @TheKingofRandom
    Good question Robert. I haven't played with black match yet. My guess is that black match burns quicker, so the only advantage I can think of is that it gives more of a delay time? It's also fun to use as improvised sparklers for my kids.
  • @TheKingofRandom
    I was having the same problem with earlier batches and recipes, but this one works for me. They continued to burn even while squished under concrete blocks. I'll test them with some homemade rockets in future projects and show the results. Thanks!
  • @UncleFunk002
    R.I.P. what a legend. My brother and an old friend have some great memories because of this video.
  • I seriously love your videos. After this one, I don't think i'll need to buy fuse ever again!
