sparkler and why make one. I think it is safe to say that everyone who is reading or read this instructable has played with or seen a sparkler. basically a tube sparkler is a hand held firework that burns slowly and produces sparks due to a powdered metal. i know some people might say "why make a sparkler when you can buy them at the shops for under $2" well firstly the ones you buy at the shops are one of two main groups of sparklers dipped sparklers and tube sparklers in this instructable we are making a tube sparkler as they can contain more composition and therefore give off more sparks. secondly shop bought are dimmer and give off tiny sparks that die as fast as they begin. So that's why i have created my own
now before I continue i have to make sure that you know this. These sparklers are more powerful than normal sparklers and create a lot more sparks that are hot and can stay lit for over a second when they have touched the ground so do not light this sparkler when your standing on a pile of dry leaves or any other flammable material if you step on the sparks in bare feet you might receive a small but nasty burn so wear shoes and never point it at anyone. People watching the show should stand at least 3 meters away. So remember to be safe and think before lighting and you will have a great time.
OK i'm glad i got that off my chest so where did I get the idea to make a tube sparkler. Well the idea to make this tube sparkler came when i stumbled on a great pyrotechnic composition that produced an immense amount of sparks and light ,which i will show you how to make later on, after thinking of many things i could use this mixture for i came up with a simple yet effective and bright sparkler.The sparkler was made at home using chemicals that aren't hard to find or buy and some tools that most house holds should have.
Step 1: Materials and Tools
# potassium nitrate/KNO3
In the sparkler composition the potassium nitrate will oxidize the reaction. with out it the reaction wouldn't get any oxygen and therefore would not burn
In the reaction sulphur will act as a fuel for the potassium nitrate to oxdize
In the reaction charcoal like sulphur will act as fuel
#aluminium powder mesh 400
aluminium powder is our main chemical and will give the reaction its brightness and sparks
Now these are the tools you'll need you should already have most of them but if not there not hard to find
# Mortar and pestle
for grinding chemicals
for mixing chemicals and for making the tube to contain our sparkler composition
for making the tube and a funnel to put the sparkler composition in the tube
for measuring chemicals
this is a good thing to measure your chemicals in
A pole or a long piece of heavy wire to mount the sparkler on a glue stick for making the tube some masking tape or string to attach the sparkler to the top of pole or wire and a spoon for scooping chemicals. i did not include these in my photo as there need became obvious after the photos were taken.
Step 2: Step 1 of Creating the Sparkler Composition
C/S/Ai powder/KNO3 1:2:7:12
The fist step to making the composition is measuring the two primary fuels, sulphur and charcoal and grinding them together. Its easiest to make 22g batch but by multiplying everything by 2 you will get a 44g batch and if you multiply everything by five you would get a 110g batch and you get the point. Lets just start with a 22g batch. We're going to need 2g of sulphur and 1g of charcoal so get measuring, once that is done put them in your mortar and start grinding until you have a fine powder as seen in the photograph above.
Step 3: Step 2 of Creating the Sparkler Composition
Step 4: Step 3 of Creating the Sparkler Composition
Step 5: Testing Our Compound
Step 6: Creating the Tube
Step 7: Filling the Tube
Step 8: Light and Conclusion
In conclusion i believe I learnt a lot from making this instructable. In the process i learnt how sparklers work how to make them and what chemicals are used to make them. If I was to do it again there would be few things i would do differently but I would make the sparkler compound create less smoke, but a part from that I believe the out come was better than expected and i feel proud of it.
thank you for taking the time to read my instructable it is much appreciated.
