 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?

noobererer (author)Bartboy2009-10-10

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

Peekadosies (author)Bartboy2009-04-10

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

Bartboy (author)Peekadosies2009-04-12

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)

Peekadosies (author)Bartboy2009-04-13

Peekadosies (author)An Villain2009-04-09

its accully purple, the camera just messed it up there in almost every kit.

An Villain (author)Peekadosies2009-04-10

oh i have tons of purple (but not really just a lot)

Bartboy (author)An Villain2009-04-10

Reply to all: They are the new form of grey connectors. But, only some sets have purple. There is nothing different about them except the colour.

i guess with some special knex pack/project.

Best Grenade Ever! So simple yet almost no one thinks of it. If you want it to be even better use blue spacers and a grey rod for the pin. I threw it at my wall from about 15 feet away and there were pieces of shrapnel over 30 feet away! I even got hit!!!!!!

rawknexstuff (author)2009-04-20

I modded it to use 26 purple/gray connectors!

rawknexstuff (author)2009-04-19

Like a giant splodie!

DRADIS (author)2009-04-13
