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

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)

Connect the tips of the spirals with the top white connector

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

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

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

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

There are 2 set up

Its good at night, no one will suspect it
