K'nex Landmine/ grenade

This is my knex land mine that shoots out shrapnel when a trip wire is pulled. i decided to use the simple block trigger idea and make something creative instead of a gun (although you may consider this a gun, because it shoots knex pieces) any ways, you can use pretty much any knex grenade that fits itself together loosely, like mine(you just have to put a white rod on it).

Step 2: Stand

this is the stand that holds everything up. make sure to put something small but semi-heavy on the leg opposite of the trip wire. (in my case, a rock band drum pedal.)
