Is there going to be a Nerf grenade launcher?

no one knows but there is a rumor going round that there might be one coming out in 2009 called the Bull sharc gl-8 but it is probably not coming out

I would make Nerf grenades like i do. I take a two film canister, then you cut up three or four Nerf bullets. I fill the canisters with the mini bullets. I put a small piece of cardboard on top of one then I lay the other one over it. The cardboard should be in between the two openings of the film canister. Then put a rubber band around the grenade. To arm it, take out the cardboard gently. Then throw it.

There is also a grenade that you pump called the:Lanard Scatter Blast Foam Dart Grenade

You pump the end/tail and on impact or time it launches 6 bullets out of slots all over the grenade. I got one for about then bucks and it is the best thing for wars, usally for hitting people over a wall or barrier.
