Step 1: Materials

Picture of Materials
You will need:

A tube at least three inches long
Duct tape
A screw
Thin rod
Small weight (optional)
Spring a little longer than tube
String or fishing line
Rod the same width as the tube's hole

Step 2: Getting started

Picture of Getting started
Take a drill and drill a hole at least twice as wide as the thin rod on the side of the tube.

Step 3:

Insert the spring into the tube and secure it with a screw through the lower part of the tube. The place a cap of duct tape around the part of the screw sticing out. You should probably put some tape over the bottom end so bb's dont fall.

Step 4:

Picture of
cut a small notch into the bigger rod. This will help you load the grenade and stick the key under the rod and over the spring.
The video's pretty bad, sorry about that. You shove the rod into the tube, and make sure the notch lines up with the hole. You will then put the thin rod into the hoe to lock the spring. Dont put the thin rod in too far. The thin rod can be replace by anything, preferably a hook. You can then attach a fishing line to the hook. Gently place (dont stick hard) duct tape on the opening after putting some bb's.

Now you are ready to launch. This is reusable if you could not figure that out on you own. When you throw this, hold on to the other end of the line. Once its far enough, it will lanch all of the bbs as the hook is yanked out. This is convenient since you dont have to buy an expensive reusable. Put some spin on it so the bb's dont all go in one direction. If the key doesn't pull out, add a weight and make sure it is not too far into the hole. I borrowed this concept from a land mine you tube video. I also made a multi bb launcher with a big spring and attached it to the side of my gun.

This is a great Instructable, but you need to add a main image of the final project to the intro step. Please do that and leave me a message when you have so that we can publish your work. Thanks!
Can you turn this into a video because the pics you put are a bit confusing
these work great!
but i cant ever find the right kind of spring.

I built a claymore / Landmine version of this, I can post an 'ible if people want, i don't mean to be offensive but the pix in this one are unclear and difficult to follow. 
Nihar, would you mind if i post an instructable of a claymore version of this?
do people want me to post it?
lemme know

i dont get it. bad ible. so, is it just cover one end and tape a spring to it, then but a rod in to hole the spring down? and if you cape the end strong enough to hold down the spring then it wont do anything when you pull the pin.

here's a diagram.
Nihar C (author)  daelans6 years ago
you dont properly understand this. The spring is actually supported at the bottom by a screw. When the pin is pulled out, the spring is released and by no means should you put the top duct tape piece on strong. I have tested this and it works, and i plan to post a video soon But thanks, ill try and make this instructable more clear.

Get this idea off of my instructable?
Nihar C (author)  footer05 years ago
no i got the idea off this airsoft tripmine i saw on youtube and my grenade works on a different concept where the key is pulled in midair after the line reaches its limit
