How to make a cheap airsoft Madbull grenade.

Alright, so this isn't technically a madbull grenade. But it does function similarly, and is much less expensive. This uses a few household items and is very effective, requires no water balloons, firecrackers, or anything specific other than what is required in the instructions section. I have spent almost a year hunting down an effective airsoft grenade. I felt like I was about done when I saw a youtube video on this. Now, I was skeptical at first, but this is the one of the best grenades. Period. So I improved the design, then since I didn't find anything about this on this site, I decided to post it.

P.s. Sorry for the fuzzy pictures. I need a new camera.

Step 1: Getting your supplies

So you'll obviously need a few things First of all, you most likely will not have the main part in the grenade. The spring loaded party popper. So go down to party city and buy some. I bought 3 for $3.00. No you may be scared at first when the box says " One time use only" but I assure you. These are very easy to reuse. So now that you have those, you will need:

Duck tape ( Or any tape, Duck tape just looks cool.)

A small screw ( One for each grenade. It is very important you get the right size so try a few different types)

An easter egg. ( Preferably with holes in the top, and I think yellow looks coolest)

Sand Paper. ( I find a rotary tool to be much easier, but you may not have one.)

A pencil.

And of course, Air soft pellets. ( I used .2 grams)

There you have it! you can start building now

Duck Tape was invented in WW1 For the army to seal ammunition cases. AND IT WAS CALLED DUCK TAPE because it was water proof

[bbot2000729]

No, it was 'Duct Tape' because it was used to seal air DUCTS.

[geniuskid9]

no ive read about it it was duck tape.

[The3rdPunch]

No, no spartan711 is correct on this one

[spartan711]

Thank you

[spartan711]

not originally, as i said it was originally called duck tape because of it's amphibious qualities.

[ebrun]

That's kinda cool :D

[YeGreatOne99]

put a small balloon or some tissue on the end and then the bb`s can fire out., its harder to reload but means you can fire quicker, say someone pops out of nowhere.Thanks

i really wish it wasnt blury, but i cant wait to build it

[agent102]

This is a sweet instructable, but where can i get the party popper?Please help

[Frank Lampard 13]

party city

[meanbean]

I found my poppers at party city. My first suggestion would be to check there.

[kenttin]

so do i have to take the egg off before firing? Please answer

[meanbean]

YES! If you don't take the egg off, it will crack. You might be able to put tissue paper over the top if you're looking for a faster way to fire it.

[h8864]

its DUCT TAPE

[heavyweaponsperson]

quack :D

[h8864]

DUCT TAPE!!!
spell it
D-U-C-T T-A-P-E

[sub893]

is it reusable?

[meanbean]

Yup.

[finn12345]

duct tape rules!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[mwagner63]

They do make golden duck tape now

[gorillailla202]

Instead of using the screw, I think a bobby pin would be better. It would hold the lid down, then you could just pull it to arm the node. Plus, instead of trying to screw the screw into top, then the side, you could just carry 50 of them in your pocket.

[invincible airsoft]

you just blew my f***ing mind!

[T-K]

great idea! i was playing around with it just now and found that the lid of a V Pocket Rocket fits kinda loosely in the opening. perhaps this could replace the easter egg and duct tape?
also, having the words "Energy Shot" on the front of a launcher like this sounds pretty cool 8)

[jagged474]

instead of sandpaper or a dremel i used the metal file off of my pocket knife. same results.

[sub893]

nice job, because i dont have a dremel

[atomiclegocreations]

nice implementing! i lost my small pocket knife that had a file on it, but then i got a bigger one!

[Oicu81shoe]

Yeah this thing is great! Though its not really a grenade its more of a mini shotgun. 5*

[aRejectedKitten]

IF YOU GUYS WANT A LAUNCHER I COULD PROBABLY COME UP WITH AN IDEA ON ONE(srry didn't kno i had caps on)

[2bad4u]

This is awesome... though I have never seen spring loaded party poppers....
this is probably some of the best work i have seen on a cheap reusable grenade...

but thats just it... its not exactly a grenade... I want something just like this except it fires on impact.... how can you or me if I make one make it so that it fires when the bottom of your grenade is struck... i'm sure it is already heavy enough that if you threw it would land bottom down most of the time... once that is done... I could easily make it shoot out instead of up (noting that it is landing and firing with the egg part up)...

anyways... great job... think about my idea though... :D

[aRejectedKitten]

this is a tactic i used on my nerf darts when i was in to nerf, take a 6 ring of caps(the ones for the revolver) and SLOWLY AND CAREFULLY scrap out the white powder from the inside and put about a teaspoon into the very tip of the. cover up the holes, and put plastic wrap over it so it's not spilling over the bbs. and hopefully, if you launch/throw it with about 20-30 pounds of force, then you have your majic jack VOILA

You do realize that the madbull grenade shells are for airsoft 40mm grenade launchers. A warning to tothers. this does not do the same thing.

[zombiekiller42]

i made one

[airsoft master 25]

that thing is sweet

[The3rdPunch]

Amazing! You should post an instructable on that.

[meanbean]

Nicely done.
Couldn't have made it better myself!

[zombiekiller42]

thx

[pieman12]

i found that using tisue paper and scotch tape on the end works really well.

[inventorguy789]

Cool grenade... i made an airsoft grenade too check it out at this adresss http://www.instructables.com/id/Airsoft-Grenade-9/

I got one and me and my friend figured that duct tape would work better than an easter egg you just take the tape off when you're ready to shot it. plus my popper is resettable with pushing down and turning it so that it latches. but you're the one who made it. that is just mine. anyway thanks for the idea because you're the one who gave it to me :-)
