    throw it wile holding on the pin(just be careful)

     Nice nade, dude I throwed it to the garden and i can;t find half of the shells back 5* 

    This is SO COOL! 5*! Now, can you make a gun that can shoot it?

    i had a cool idea of this but im too lazy too build it :P

    i wish, but im not a super fan of knex and i only have 1 set, nice idea though.

    I did, it goes about 20 feet, then blows up. *hint: just shoot it out of an open-barrel sniper (keep the red rod in, but take the connectors off)

    now make an instructable for it!!!!!

    this is the first grenade i yhave ever built that actually workeed. but it ended up exploding in my hand. OW!
