How to make simple Grenade Launcher

Alright, what you are about to make isn't a real grenade launcher. It doesn't shoot grenades, but the ammo used here is much like the Brute Shot in Halo.

Things You'll Need

• 2 identical tubes, large enough to put a Poland Spring bottle inside them.
• Poland Spring bottles.
• Tissue Boxes.
• Electrical tape, or other strong tape such as duct tape.
• Strong scissors.

STEPS

The Ammo

1.) Take your Poland Spring bottle (T is the top, B is the bottom, and W is the wrapping)

2.)  Twist the bottle under the wrapping so that it is very tight. Then take your tape and tape it very tightly in such a way that when you release the bottle it doesn't undo it. There you have your first piece of ammo. the more you make, the better, because you can launch them without the gun.

 

 The Gun

1.) Take one of your tubes and cut it from end to end. Cut the tube again leaving 1/2 inch from the first line. 

2.) Cut it down the middle.

3.) Again: Space between cuts are 1/2 inch away.

4.)  Fold over it and tape well.

5.)  Tape off one end of the tube so that nothing can penetrate it.

6.)  Cut out a rectangle at the end of your second tube. #This cut on top of the tube should be big enough for the ammo to be dropped in.

7.)  Cut out another rectangle on the other end of the tube and below  (Make sure you leave one side of the rectangle you're about to cut alone).

You are trying to make a flap, not a hole. Or diagonal from the first rectangular cut.

 1. Insert your tube with the taped end into the first tube with the rectangular hole. Take another Poland Spring bottle, and cut it into a funnel, cut the bottom off, and cut the cap part off, for it to looks like a pyramid with a hole on top. Make sure you are able to insert another bottle into the funnel you have made. Make sure the bottle's cap is sticking out of the funnel.

2.  tape your funnel securely to the tube. Make sure it is on the end with the rectangular hole, on the bottom.

3.  Cut the top of the box and bottom (the largest sides.) of your tissue boxes. # Tape the boxes so they are stacked up high. Leave the highest box's bottom uncut. You just made a magazine for your "grenades."

4.  Tape the magazine tightly to the tube.

5.  Cut the top of the tissue box so that you can open the top like a flap.| You should be able to insert the bottle in the flap on top of the tissue box.

6.  With your magazine loaded, pull the tube with the tapped off end out, and let a bottle fall in the cylinder. Push the bottle forward with the tube into the funnel. Fire the cap as seen above in "HOW TO LAUNCH THEM." Open the flap on the bottom of the tube and let the shell fall out. Close the flap, and pull the tube with the tapped off end, back, so that another bottle falls in place. Repeat and enjoy.

Launching it

1.) Without gun: Hold the bottle firmly and slowly twist the cap until you hear a small hiss. As SOON as you hear it, twist the cap as fast as possible. Make sure you don't have a tight grip on the cap or you will have to slow it down.

2.) You should hear a loud pop and water vapor should be visible giving a smoky effect and the cap can fly anywhere from 20 to 100 ft,

3.)  With Gun: When you have the ammo in the funnel, hold it below the cap with one hand and hold the cap with the other. Doing the same method as seen above, hold the tubing under your arm.

Warnings

• Don't shoot at people's eyes.
• Never shoot animals. While humans know it is only a game, they feel actually like they are in danger. Plus someone could perceive this as you are trying to kill the animal and call law enforcement!
• This does not work against the newest razor wire. This is steel with special component so it resists regular explosions.
