Introduction: Airsoft Trip Wire Landmine

Your in a tight battle situatoin and know your going to get ambushed, so you put one of these babys down and boom!!This uses no exploseves just a spring and some pipe.

Step 1: Materials

Picture of Materials

What you'll need:
6 inches of 3/4 inch pvc pipe
3/4 inch end cap
3/4 inch 45 degree angle piece
spring (should beable to slide through pipe)
glue stick cap
little screw
fishing wire
stick (to put wire)

Tools you will need:
pocket knife or drill(i didn't have one)

Step 2: Make the Holes

Picture of Make the Holes

First make a hole to where you want to put the nail (the shorter the better)

Then put a hole near the top to put your little screw(to keep spring from shooting out)

Step 3: Installing the Spring

Now put the end cap on your pipe(opposite of little screw)
put your glue cap on your sping (inside the pipe)

Step 4: Priming It

Picture of Priming It

Put your little screw in and push down spring(i used a pen)
and put you nail threw the hole So the spring is pushed down.

Step 5: Loading

Picture of Loading

You can use just flour or just bbs or for really good effect use both!!!!!!!!

Step 6: End

Picture of End

Now you put your stick with the wire on it in the ground and on the other end with your nail tied to
it in the mine.You spray paint it and put leaves over it and your done.

When some one hits the wire the nail pops out and the 45 degree angle top guides the bbs (or
flour or what ever you used ) toward the person who detonated it.

It shoots bbs about 20 feet and flour about 8 feet.

militarymonster (author)2011-02-22

HeadBanger (author)2010-02-06

Good idea, but next time when taking the photos, don't use your flash. The photos should turn out a lot better.

shot789 (author)HeadBanger2010-02-07

 ya i know i was using a crappy camra but i have a hd camra now

 Macro is your friend...

shot789 (author)iBurn2010-05-01

who is macro?

Ballistaman (author)shot7892010-06-20

Macro is a mode on your camera that allows you to take photos closer with more detail. you normally push left on the d-pad. The macro symbol is a little flower.

Who is macro? LOLOLOLOL!!!

Awesome :p

I saw this on youtube and wanted to post it on here but you already had it up!
I would spray paint it camo and put flour and bbs in it!

kve23 (author)thing 22011-02-05

i made mine camo green with strips of camoflage cloth as guillie. its alot smaller and i made some mods to it.its still awesome

thing 2 (author)kve232011-02-05

Do you have any pics? If so I would like to see them!

kve23 (author)thing 22011-02-16

this is it. its pretty sweet.

thing 2 (author)kve232011-02-16

What's the extra piece of pvc for? Is the orange bit a glue stick cap? Also what is the threading for?

Thing 2

kve23 (author)thing 22011-02-26

so you can stake it to the ground and yes that is a glue stick cap but no there is no threads. i think your thinking of the spring.

thing 2 (author)kve232011-02-27

How do you get the glue cap to work for you without bending or poking a hole in it?

kve23 (author)thing 22011-02-27

i put the pin all the way through and it really doesn't dent it

Fire Explorer 3 (author)2010-12-02

Hmm...tryina' figgure out how to mount this with the 45* angle, so i can use it under my gun w/o the bb's hitting my gun, or the ground, or shooting sideways...or, a way to use it as a real shotgun, but with better range... (Bigger pipe and spring, but how to quick reload...any ideas?

shot789 (author)Fire Explorer 32010-12-16

For a quick reload you can cut a small line in the pvc pipe and use a screwdriver or something to push it down. I have been meaning to post how to make a undermounted grenade launcher/ shotgun but i just havent had the time but i will soon.

kve23 (author)shot7892011-02-05


Fire Explorer 3 (author)shot7892010-12-18

Please do...cuz it may well become my primary... my crappy crossman crapped out on me...

kve23 (author)2011-02-02

ive gotta make 1 like that

wawhosed (author)2010-11-26

This is a good project, I have made one before. Also, you put a s****y spring in there.

evilgenius32 (author)2010-08-16

I like how the 45 degree angle keeps the spring from coming out. I tried one like this but without the elbow and had troubles with it. This one would work a lot better.

siv (author)2009-05-19

would the mine work for paint ball also or not

shot789 (author)siv2009-06-02

ya but you cant put the 45 degree angle on unless you use bigger pipe

Thundertydus (author)shot7892009-06-11

Mount it on your gun and add on a better handle and abolt action design, it makes a great nade launcher

Ballistaman (author)Thundertydus2010-06-20

put some thin paper on the front of a pipe without the 45 degree angle when doing this. it keeps the bbs from sliding out.

jackas (author)2010-05-10

 sprinkler's have great springs i use them

airsoftbeast40 (author)2010-04-26

there is another instructable on this website thaty is the exact same thing and it is a little better done(meaning the product) so check it out-

Goalie1 (author)2010-04-18

I just made it, and it works great!!!!

Thundertydus (author)2009-06-27

No problem, it's what i do.

HeadBanger (author)Thundertydus2010-02-06

Yeah, that's a great idea. Thanks for that.

 Hmmm... Airsoft under barrel shotgun?

gregsmith55 (author)2009-11-23

so u put the spring and glue cap in put the screw in and push spring down and put nail in to keep in place????  also do you jus put the bbs/flour in ontop of the spring and stuf im a lil confused

shot789 (author)gregsmith552009-11-24

what u do is  put the glue cap on the spring and use a stick or something to push it down then put the nail in the whole so the spring is pushed down. then you put the bbs or whatever in it and then when the nail comes out the spring will shoot up and the bbs will come flying out.

gregsmith55 (author)shot7892009-11-27

alrite thx

2bad4u (author)2009-10-23

my friend and I are huge into airsoft and have thought about making this design but we can never find a spring the size we need and the power we need it to be... any suggestions...

shot789 (author)2bad4u2009-10-25

i got my spring from a crappy spring pistol but if you dont have one just find a spring that fits in the pipe and if its not strong enough just strech out the spring so it is long enough.also if your in the us i think home depot sells springs. or just make your pipe the right size.     hope that helps

2bad4u (author)shot7892009-10-26

I didn't think about the crappy spring pistol thing... but yeah I did look at home depot and at lowes but all I could find were either tension springs or ridiculously huge compression springs...

WEEZERRULES (author)2009-10-21


shot789 (author)WEEZERRULES2009-10-25

when the nail is pulled out the spring pushes all of the bbs (or whatever u put in it) out of the top and the 45 degree angle pipe aims them towards the enemy

Airsoft_Maniac_96 (author)2009-05-02

i would take like 10 of these and then put them all in 1 area so when the dude walks buy he will pay


kyro159 (author)2009-08-08

how much does this thing hurt. when it goes off it just doesnt seem like it would have a lot of power with only a spring.

shot789 (author)kyro1592009-08-10

I know its just a spring but it is about 300 fps which sounds like it doesnt hurt because thats the power of a spring pistol but remember when it goes off its only about 6 inches from u so yes it does hurt and gave my friend a few good welts

pizzus (author)2009-06-18

this is great man, i havent thought anything like this

tehgreatiam (author)2009-05-20

ahh! turn off the flash!

BADWOLF1 (author)2009-05-06

shot789 (author)BADWOLF12009-05-06
