a modification to a famous knex grenade by halo99. except without the shrapnel, and with 3 rubber bands.
16 red connectors
8 yellow connectors
2 white connectors
2 single slot connectors
a yellow rod
a grey spacer
a Y black connector
Step 1: The Pin
This is the most simple thing in the world, second to rocket science of course.
Step 2: The Grenade
Make this. you don't really need instructions for this part, do you?
Why, just look at those pictures! OMG!
Oh yeah, don't forget da rubber bands.
Step 3: Putting It Together/ Blowing Up
insert the yellow rod with the grey spacer in the bottom of the grenade and squeeze until the black connector on the other bit can go on sideways. Then to fire, put your hand in the position shown and flick the grey connector up. It will pop of and the yellow rod will drop through. Then throw!
It wont explode while the pin is in, actually it is very strong.
Blast radius: 5 meters.
Have fun destroying walls.
