Introduction: K'nex Landmine

Shoots White Rods

From https://www.instructables.com/id/ECUWRX2OCAEWZ990BV/ by You and Moded it

In the video, I know the mines are there, I dont know if you can see the white rods shoot, but its still a good thing. Some one walked in my room and I could tell because I heard the things shoot


Step 1: What You Need

This is a simple design

you need (for one mine only and no cannon (cannon later)):
48 green rods
24 green connectors
9 white connectors
8 yellow connectors

This is the design, that is 1 mine

all the green connectors have a green rod at both ends of them

Notice that one of them has the extra white connector (this is for the top)

Step 2: Connect It All

Connect the tips of the spirals with the top white connector

Step 3: Making the Gun

You need 3 more white connectors for the gun
7 grey connectors
1 yellow rod
1 blue rod
2 white rods (it fires a white rod)
2 orange connectors
1 elastic band

follow that design

Step 4: Connect the Gun Back to the Main Mine

the Yellow rod that is in the white connectors should be at 9:00 and the green rods that go into the white connectors should be at 12:00 and 6:00

Step 5: Connect the Gun Back Into the Main Mine

Connect the white connector back into its original position

The top green connector should be at 12:00
The yellow rod should be at 9:00
the bottom green connector should be at 6:00

Step 6: Insert String

Insert some string into the white connector at the top of the mine

Then tie a knot to the grey 1 slot connector that is attacked to the white rod

This rod will be facing down
when the string is pulled, the string will pull the conector, pulling the white rod, pulling the connector that is connected to the white rod, that releases the firing rod and fires the rod

Step 7: Make Another One of These, and Plant

There are 2 set up

Its good at night, no one will suspect it

this is cool i might mod it to have more barrels and make it shoot nerf darts

help your land mine wont shoot

my dad picked it up and the ammo shot right in his nose it was hilariously funny but hes ok

i just built this bad boy and my mom thouhht it was a hat so im like no n dont pick it up its loaded!! luckily she didnt. ;] ...great instructable though i like it alot...you can make this smaller where u have a long screw driver taped to basicall just the gun...and paint it camo. then have the wire just connected to where u would normally tie it to the gun..therefor its just a lot smaller and harder to see if u were to use it in say airsoft or something of that sort.

I have an idea: you should make a design with multiple barrels, make a true trigger, dig a hole in the ground, cover it back up with dirt - leaving the very ends of the barrels exposed, and when someone steps on the trigger it will release the pins on all the barrels and shoot straight up.

Hmmm, if you think that'd be cool then you should look at my CS2.
