Knex Grenade (Stielhandgranate)

About: I'm in my final year of Product Design at uni so I don't have as much time for tinkering as I'd like. When I'm free I enjoy making props,mechanical models and an ever-growing 1/72 model of wartime Stalingrad...

Intro: Knex Grenade (Stielhandgranate)

A knex stick grenade that has a blast radius of around 3 metres depending on elastic bands. The grenade fires 8 green rods in four directions and has a handle for easy throwing. Lots of people posted knex guns so I thought I would post a grenade!!!

Step 1: Pieces

You need:

10 White connectors
4 Yellow connectors
8 Green connectors
8 Purple connectors (individual) or 4 in pairs
4 Red connectors
8 Grey connectors
16 Light Grey connectors
8 Tan connectors
4 Red/Orange rods
24 White rods
8 Blue rods
4 Green rods (excluding ammo)
16 Blue spacers
2 Square Mini Panels/ 2 White connectors+ 8Green rods
8 Rubber bands

And some flexible wire

Step 2: The Handle

Take the four red/ orange rods and connect them to the 2 white connectors like this.

Step 3: Handle-grenade Connection

Get 2 green connectors and a green rod and connect them as shown and then do it an another 3 times and connect the four parts to the panel.

Step 4: Main Frame

Take 4 White and 4 purple connectors and 16 white rods and put them together like this!

Step 5: Charges

follow picture

Step 6: Construction

connect the charges to the frame like so....

Step 7: Construction

add the top and handle like this

Step 8: Finished

Now your grenade is finished all you have to do is make the circles that explode the grenade.

Step 9: Firing Rings

Get the wire and use some pliers to snip the wire so it is around 9cm and make it in to a cirle with a diameter (width) of around 1.2cm - 1.3cm. Do this a few times as unless you tie the rings to the grenade they are very easy to lose!!!!

Step 10: Loading and Firing

Take the top and bottom off the grenade to expose the firing rods, then push all of the rods into the middle like in the 4th and 5th pictures. Then all you have to do is put the green rods in the barrels and THROW!!! The impact of the grenade hitting the floor or the wall will make the grenade explode and fire green rods everywhere!!!!

    did you see on the news this morning there was a squirrel that got its head stuck in a yogurt cup? They called it "one squirrel, one cup" (as in two girls, one cup)
