Introduction: Pocket Shot

This instructable will show you how to make a cheap and easy "slingshot" small enough to fit in your pocket but strong enough to break stuff! A word of caution before we get started, depending on how well you make this thing you could seriously hurt yourself or others, the household pets, or various nick nacks. Now that you are properly warned, let's go!

Step 1: Gather the Needed Materials:

one regular sized round ballon
one empty juice bottle
scissors
optional: corn starch or baby powder

Step 2: Cut Off the Top of the Juice Bottle

Just as pictured, you want to cut it so that you are left with a bell shaped piece. You can throw away the bottom piece, we're done with it.

Step 3: Trim the Edge

Turn the top upside down and look carefully at the inside edge. If any of it is curled or turned inward, trim it off until you have a nice wide opened without any curled edges.

Step 4: Cut the Balloon.

Almost done. Cut the neck of the balloon off right where the picture shows. Next cut off the lip on the other end of the neck and set that aside. You should be left with what amounts to a round rubber pouch and a makeshift rubber band.

Step 5: Attach the Balloon to the Juice Bottle Top

Stretch the balloon over the neck of the bottle top. Make sure you get on as straight as possible. Did you notice the grooves on the bottle neck? Take your make shift rubber band and slip it over the balloon and into the deepest groove on the bottle neck. This will hold the balloon on nice and tight. If you took the time to grab some baby powder or corn starch, drop just a pinch of it into the balloon and shake it around a bit. This will keep the balloon from sticking to itself in the near future. The finished product should look something like the picture below.

Step 6: Now to Shoot Stuff

You want to hold this thing by circling your index finger and thumb around the neck. Drop in your choice of ammunition and grab it with the opposite hand. Pull it back, aim, let it go! You can shoot anything from it that you can easily drop in including sharpened pencils, crayons, etc. The types of ammo that work best for it are anyhing the size and weight of a pencil eraser. Be careful, if you made it right you can break windows with this thing, and hurt people or pets. There are many other ways to make this stronger, and some other materials to use to make it better, but hey I gotta let you have some of the fun of experimenting! ; )

what dose it shoot

author

Paper balls, foil balls, steel ball bullets, plastic bb bullets, anything you can think of

These are fun to shoot but I find they don't last long. The rubber of the balloon can't take the forces involved and will eventually tear, so a new balloon then has to be used. Is there some way to ease the load on the rubber so it lasts longer?

You could try use double balloons...trim two balloons the put glue on the outside of one and glue it inside of the other one.

Good Project. You could just time of that bell/cone shape where you put the ammo in to the bottom...as far as you can go.

Grant Thompson TKoR has an epic video on how to make a "Pocket Slingshot" btw.

Heres the video...hope it helps:

I've just made a similar one and it can shoot about 70 metres!

there could be less chance of the balloon slipping off if you wrap a rubber band around the neck a few times (that's strangling).

I shot some bbs and it went farther than I thought it would.

you can also use a hair roler and a latex finger off of a latex glove its stronger

id put tape or string to keep ballon from sliping off and hitting you in the hand

A zip-tie would work well too...

i was looking and thinking and why not keep the cap and make it basically just the threads so you can stick teh baloon on and then the cap over to make it stay and so you can shoo through it still

Now that's a great idea. I was just thinking along those lines

author
SBD made it!(author)2007-03-29

I can honestly say I have never thought of that. Try it out and let the rest of us know how well it works. Good thinking! ;)

author
dcshoeco33 made it!(author)2007-03-30

it works very well i havent had the baloon fall off once :)

author

Cool, what bottle did you use?

author
i+make+shooting+things made it!(author)2007-03-29

this is the most powerful, simplist, smallist gun iv ever made. I put a BB through 3 dr. pepper cans. it works great thank you.

BTW do not shoot short dowels or short matches, the dowel went throught the ballon and into my hand not fun.

If you use the neck of the balloon as a rubberband it is usually tight enough to hold it on. Take another look at step 5. Of course if that is not working for you then mabye you cut the balloon so that the opening is too big or you need a smaller balloon.

author
SBD made it!(author)2007-03-28

Another thing could be the type of bottle you used does not have a deep enough groove to put the balloon neck over to keep it on tight enough.

Is it as powerful as an airsoft gun when using airsoft ammo? rsvp.

author

I stick stuff like flour in the balloon or my homemade paint ball's in ther. P.S. If you would like me to post my homemade paint ball's answer this message and I'll post it.

I know. Like, if you type in gun in the search bar, half of them are Knex guns!

i like knex guns too, but when im trying to make something like a rifle, not a knex one, it pisses me off too think that there might be what i was looking for but i have to go through hundreds of knex submissions AND i end up not finding what i need. im like "what the hell!?"

author
Phoghat made it!(author)2008-06-29

So true. Do a search here for a Firefox extension that automatically deletes from your search Kenex projects and gives you the ALLSTEPS view too.
