Introduction: Cobra Weave Exploding Stick Bomb

Picture of Cobra Weave Exploding Stick Bomb
The Cobra Weave Exploding Stick Bomb is pretty dang cool. I've seen a lot of the smaller stick bombs on Instructables but none of these chain ones so I'm really excited to share it with everyone. 
The chain is pretty easy to put together and is reusable so there is plenty of entertainment value. It's awesome to watch the stick bomb in action, rising like a cobra and noisily spitting sticks out as it goes. Watch the video to see it in action!
I would love to see other people's cobra weave stick bombs so if you make a cool one be sure to link in the comments. 

Step 1: Materials

Picture of Materials

What you need:
-a big ol' pile of popsicle sticks
-string (optional)
-your hands and maybe a buddy's hands too

Step 2:

Picture of

Cross two sticks into an "x" shape like in the picture. You want it to be a little slantly so that there are two obtuse and two acute angles. The stick on top will be stick 1 and the stick on bottom will be stick 2, see picture for note.

If using two colors, these first two stick should be the same color, in my case green.

Step 3:

Picture of

Add a Stick 3 by tucking one end under the end of Stick 2. The new stick should go over Stick 1. 

If using two colors then the stick added in this step should be the other color not used in the previous step, purple in my case. 

Step 4:

Picture of

Add another stick by tucking it's end under Stick 2 and letting the rest lay over Stick 3.

If using two colors then add a stick the color of the ones you used to make the "x" shape, in my case green.

Step 5:

Picture of

Continue adding sticks by tucking the end under the opposite color stick and letting the rest go over the other stick until you've reached the desired length. Just remember that patiece will pay off and the longer the stick bomb you make the longer explosion show you'll have.

Step 6:

Picture of

If you want to be able to trigger the stick bomb from a distance then you can attach a pull string. Simply tie a piece of string to a stick then use that to bind the working end.

If you don't want the pull string then just add a stick so that it is under both ends but over the middle stick, as the picture shows. 

Step 7:

Picture of

When for the action, give the pull string a nice tug or remove the binding stick by hand and stand back. If all goes well your cobra weave should rise up like a wave while sticks are wildly thrown across the room. Enjoy!

I made a really long one but put sharp turns in it and sharp turns don't work with these try really wide turns, it was hard at first but once i got it down it takes me 15 minutes to make a 800 stick chain.

dat's fast

Griffinisaacbourbeau (author)2016-12-17


you probably need too use jumbo popcicle sticks if you aren't using them

Samueltinapple (author)2017-04-20

it's actually pretty easy thanks

Griffinisaacbourbeau (author)2016-12-17


Griffinisaacbourbeau (author)2016-12-17

i just cannot figure out how to make it.UUUUGGGGHHHH

WhisperTheEmo (author)2016-09-06

I have searched YouTube for quite awhile on how to make a cobra weave, but they confused me. yours taught me how to make one without getting lost on what to do. if I can successfully make one, I'll put it on here

hegure_ryu (author)2015-06-15

I made it. Showed my kids, they jumped then thought it was cool.

AjayR2 (author)2015-04-12

SEW HARD TO DOOO!!coool though

mcdonaldr (author)2013-11-20

difficult but cool

dspencer9 (author)2012-11-21

I'll do that.

OutdoorManiac (author)2012-08-01

thats a cool idea ill try later

patriotsman (author)2012-07-25

can you use small popsicle sticks?

Jedi_man (author)2012-07-16

Wait... did those just continuously explode... O.O

Jetpack5 (author)2012-07-11

This I will have to do when my nephew is back from visiting...

sherrycayheyhey (author)Jetpack52012-07-11

It is so fun! If you can, you should stop by Walmart and buy a big box of them for about $5. The big ones are are usually easier to work with and if you have some extra time you can dye them in a little bit of paint and water.

DANGGIT I HAVE NO POPSICLE STICKS!!!!! AAAAARRRRRGGGGGGHHHHH!!!!!!!!!!!!!!!! >=( >=( >=( !!!!!!!!!!

GASSYPOOTS (author)2012-03-23

how do these things work!?!?!

yapoyo (author)GASSYPOOTS2012-04-08

the elastic tension is stored in the sticks, and when the stick is removed, the tension is released, making it blow up. As for the wave effect, i am not sure but i think it has to do with newton's third law of motion. Im only thirteen so dont expect me to be a real scientist.

Don't sell yourself short. Age isn't a qualification.

yapoyo (author)2012-01-22

In the second video that was a mongoose detonation. do it the other way for a cobra detonation. Also, can i do it with the thin popsicle sticks(The ones that are on popsicles)

yapoyo (author)yapoyo2012-04-08

never mind i FINALLY got some jumbo sticks

the poodleo (author)2012-01-14

thats so cool a very neat instructable, i love it.

Queentut (author)2011-11-14

Thank you so much! I've been wondering about this all summer! The guy from AGT did this! Super cool!

klerik (author)2011-11-08

Pure Awesome! So gonna try this with my daughter this weekend!

AMAZING! Lol. It would make a great April Fool's prank. Say, buy a few 100-packs of Popsicle sticks, start a chain at the foot of the bed before the victim wakes up, and string a stick bomb all the way around the room a couple of times. When the victim gets out of bed, he/she will step on the end of the chain, trigger it, and then get scared out of their wits when they see something that seems to be digging up the floorboards in their room! Perfect!
Very good Instructable! 5/5, faved, and voted.

My provider has YouTube blocked. Is there any other way to video your creation?

proxy server :)

WPee (author)2011-09-25

DON'T STOP NOW.... Do a Cobra Weave in a complete circle !

That way when it comes FULL CIRCLE the un-doing will continue to DO the un-doing of the un-done and result in a re-doing of the un-done.

Ps: use BLACK popcycle sticks to prove the BLACK HOLE idea and video it in complete darkness.


VampiricPie (author)WPee2011-10-04

Talk about circular logic. ^^

WPee (author)VampiricPie2011-10-05

Eric -
YEP! We're HEAVY on the 'circular' and very LIGHT on the 'logic' :-) :-)

astrong0 (author)WPee2011-09-26

thy logic is infallible.

nerd12 (author)astrong02011-09-28

yes, truly, thou art truly a 'natural' philosopher.

WPee (author)astrong02011-09-27

Astrong0 - Sherry did a great 'basic' demo,
BUT now it's up to the rest of us to help her complete the Cobra circle.

sherrycayheyhey (author)WPee2011-09-25

AHH! I love it! It would be so cool if putting them in a circle formation meant continuous cobra weave fun.

WPee (author)sherrycayheyhey2011-09-25

Sherry - my guess is ---
When someone with a (large) bit of Photoshop skill gets a hold of your DEMO and does their PShop-Magic there will be a 'continous' Cobra Weave hitting the Internet... so keep me posted.

sherrycayheyhey (author)WPee2011-09-27

I'm thinking it may just be easier to figure out a way to layout the sticks to make them actually do that than to try to photoshop it lol

WPee (author)sherrycayheyhey2011-09-27

Sherry - "STICK with it" ...and a solution will POP UP :-) :-)

Celine1107 (author)2011-09-26

Hahahahah fun I gotta try that some times!

mmulhall (author)2011-09-26

Do you use normal Popsicle sticks for this? I feel like they're too thick and/or not long enough and keep popping out on me :(

tabbas1 (author)2011-09-25

Check out this type of thing with Kinetic King on America's Got Talent. I'm definitely trying this

wrestlefan2 (author)2011-09-25

The KINETIC KING did this on this past season of America's Got Talent. He went for the world record and if it all would have gone off without any problem, he would have gotten it.

If you didn't watch AGT this season, do so. The Kinetic King so to the top 10

nocount (author)2011-09-25

This is the same kind of process thing that Kinetic King used on Americas Got Talent but his was WAY more complex. I wondered how it was done. Thanks for the 'structable. The longer the chain is the better it looked.

sherrycayheyhey (author)nocount2011-09-25

I bet he had an awesome layout but it's so easy to do that I wouldn't really consider it a talent. I hope he did flips or danced around it haha. I'm starting to get crazy ideas about how he could have spiced it up so I guess I'm going to have look up his performance.

nocount (author)sherrycayheyhey2011-09-25

got to AGT website and im pretty sure they still have the link up to his performances. He made it to the semi finals..

MomLovesElectro (author)nocount2011-09-25

the "Kinetic King"

or this one...
