Introduction: Simple Firecracker

Picture of Simple Firecracker

This is a simple / cheap firecracker you can make with four items and 5 minutes of your time.

First of all, I want to remind you that fireworks are dangerous .. even the cheap ones. I am not responsible for your actions.

With that said, let's get started.

Step 1: What You Need:

Picture of What You Need:

- Tape ( any kind ... duct tape, masking tape .. etc ... but scotch tape worked the best for me)
- Two nickels
- Roll of caps ( caps that you put in cap guns)

*Note: I got these caps at walmart and on each roll is 5 separate strips which is all you need for one product.

Step 2: Folding Strips

Picture of Folding Strips

- Remove one strip from the roll.
- Fold it in half ( The long way .. see image below ).
- Fold all 5 strips.

Step 3: Wrapping Nickel

Picture of Wrapping Nickel
- Take one of your folded strips and begin wrapping it around one of the nickels.
- Then take a second folded strip and make a second layer.
- Tape the end to hold it down.
- Do the same for the second nickel.
- I usually do 2 strips per nickel but you could do as many as you see fit.

  • Does more strips = Louder bang ? I'm not sure .. I would think so but try and see.

Step 4: Putting Them Together:

Picture of Putting Them Together:
- Now, take both of your wrapped nickels and put them together as shown below.
- Tape the crap out of it.
- The image below is not the final so imagine that all taped up.

  • Remember, it's not about how much tape you use, it's how tight you tape it. Compression is key.
  • I used duct tape but I would highly recommend using scotch tape. I am not sure why exactly but the bang was about 5 times louder with scotch tape. However, I got more smoke using duct tape. ( Small puff of smoke .. nothing to get excited over ).

Step 5: How to Use:

Well this step is pretty obvious. Just find a hard pavement like surface and whip it as fast as possible. It should bang on impact. The bang is pretty loud depending on how well you make it and at night you can see the spark.

Have fun and be safe !

  • I'll get a video here as soon as I grab some scotch tape.

this is called penny bomb.....................................

scotchtape is simply a strip of plastic with glue on it and ducttape is woven so where scotchtape suddely breaks with that nice hard sound the fibers in the ducttape restraint the energy and break only slightly

i through TNT in a fire once .... my friend died

first of all is that true ? and if not knock it ,off death is not funny

BOOM5601 (author)BstnRedSox33122009-11-15

You need a blasting cap to ignite trinitrotoluene.

Scar16 (author)BstnRedSox33122009-11-10

yeh well mine dide to so shut up

Yeah right BstnRed Sox 3312

ilpug (author)BstnRedSox33122009-07-14

its hard to light tnt with fire, and even when lit, it doesnt explode much morethan an equal wirhgt of gunpowder. what really makes tnt blow is the explosive force of a blasting cap that compresses the molecules and make them react violently, ie, explode. if your frind died, that sucks, but give proof or i wont believe u. also, how hte hell did u get your mitts on TNT?

matt7 (author)BstnRedSox33122009-05-11

yay right

Nice ible. I've got a suggestion for the folks on here. Take a buttload of sparklers and empty them into a film canister. pack it in really tight. Make a hole in the cap and use whatever you want for a fuse. I got a white flame that went up at least 10 feet. There wasn't even a trace of the canister left, it was obliterated. And it burned the sidewalk. Oh yeah, wear sunglasses.

zack247 (author)russian52010-01-04

awesome. im gonna try putting that into a toy hummer, and seeing how much damage that causes (i might try 2, not sure)

russian5 (author)zack2472010-01-22

Good idea. I'm going to try putting one of 'em into something metal and see what happens.

zack247 (author)russian52010-01-22

awesome. i cant wait to see the results

Pyro Master (author)2008-05-28

Were do i get caps

fade400 (author)Pyro Master2008-05-29

I got mine at walmart. But I have also seen them at the dollar store. You should be able to find them at any place that sells cap guns.

mechamaggot (author)fade4002009-03-19

could i launch this out of a potatoe gun or would it go of in the barrel?

zack247 (author)mechamaggot2010-01-04

you probably could if you put something behind it to absorb the shock

clayball97 (author)2009-03-25

what happens if you set one on fire like a real firecrackers

fade400 (author)clayball972009-03-25

haven't tried .. haven't made one in a while either. but you should try and let us know how it goes =)

macgyver603 (author)fade4002009-06-18

You could stick a sparkler in the end and light that as a fuse.

clayball97 (author)macgyver6032009-06-18

good idea i could use that soon with 4th of July coming up

codongolev (author)2009-06-09

I've seen it done where the caps are wrapped around a sparkler and taped in place. that way there's a fuse.

Jupitane (author)2009-05-23

Is this a firecracker???

matt7 (author)2009-05-11

its easier to just take all five and drop a brick on them or put a brick on the and jump ont it

fade400 (author)matt72009-05-12

just cuz it's easier doesn't make it more or less interesting.

wiiman07 (author)2008-06-12

it was three am at scout camp i couldn't fall asleep so i made one of these and chucked it into the fire it was so loud that everyone at my camp site woke up GREAT INSTRUCTABLE!!!!!!!

goeon (author)wiiman072009-04-18

camp gardener?

mazeka.14 (author)wiiman072008-12-03

sounds lik you enjoy camp:D

mazeka.14 (author)mazeka.142008-12-03

miss spelled.

AnarchistAsian (author)2008-07-06

it's probably louder with scotch tape, because it tears faster and holds more pressure than duct tape =>

gschoppe (author)2008-05-04

the most economical way to do this effect is with two bolts and one extra long nut... you screw one bolt half way onto the nut, place a single, or stack of caps in the center of the nut, and screw the other bolt on over them tightly... that way you have bolt-cap-bolt, surrounded by the nut... when you throw it and it goes off, the gas has to escape through the threading, and it appears to vield a more satisfactory "pop" than my earlier experiments with rocks... btw its economical because its reusable, and only uses 1-4 caps

fade400 (author)gschoppe2008-05-05

do you have a picture. im not sure i understand exactly.

i make shooting things (author)2008-05-03

where can you get those iv seen the snapper things that you throw on the ground and they go pop but never a roll of them

well they are normally used for cap guns so find a place that sells cap guns. Iv bought them at the dollar store before. This time I found them at walmart.

only cap guns iv seen use individual red plastic caps or rings of 6-12 red caps for revolvers. ill look next time i got to the hobby store

PKM (author)2008-05-03

Nice variant on one of my childhood favourites. The recipe I used:
- fold caps in half down the middle
- assuming you have 100 caps per roll, count out twenty and fold the strip over on itself so you have five rows of twenty next to each other
- press tightly together and wrap tightly with packing tape, leaving the paper end of the cap roll sticking out as a fuse. I know masking tape doesn't work, we never tried duct but packing tape is the undisputed king.

Tape to a wall or something vertical in a non-flammable area (possible danger of burning fragments, keep away from dry vegetation etc.) with the fuse sticking out downwards. Light fuse and get at least a couple of metres away. This will really, really make your ears ring closer than that.

fade400 (author)PKM2008-05-03

great i'll have to try that sometime.

Ah man, I loved junior high! We used to do this with pennies (not double them up though). We'd make a whole bunch (~40) and run down the street throwing them as high as we could behind us. My friends and I would do this constantly through the summer as late in the night as we could. Needless to say we weren't well loved by the neighbors. Good times....

Cool! although I'd rather mix chemicals.........
