Introduction: Safety Goggles for Knex Guns

Picture of Safety Goggles for Knex Guns

In this instructable you can learn how to make a pair of plastic goggles out of a 2lt soft drnks bottle. You can make a version with or without string.
Without string is better cause the string gets annoying.

P.s This is my first instructable.
I dont like unwanted comments.

I will NOT be held responsible for any injury or death while wearing these goggles, they have not yet met official saftey standards.(PLEASE TAKE CARE, WEAPONS AND GUNS ARE DANGEROUS!)

Step 1: Materials

Picture of Materials

Items that you will need: A 2lt soft drinks bottle,
Insulation tape(stiky tape)

see picture for my reccomendations.

Step 2: Getting the Plastic

Picture of Getting the Plastic

Cut the top and bottm off your bottle and cut a 22cm strip from around the middle. Make it about 2 inchs wide so it will cover all of your eyes.

Use the pictures to help you.
After throw away the top and bottom of your bottle.

Try not to get coke everywhere!

Step 3: Nose and Padding

Picture of Nose and Padding

For this you will need any tape, cut a small dint where you want your nose to go and then sart to cover the edges with tape. Once all the edges are coverd it will feel smooth on your face. Using your scissors make a hole in each corner if you want to add string.

Use the pictures to help you.

Step 4: Great Your Done!

You now have your own pair of safty goggles.
Add comments and post pics if you make them.
I have no objections to changes.

1. Knex pieces don't weigh enough to actually hurt your eyes. 2. If a piece does hit these hard enough to hurt you, the plastic will just bend, and it will hit you anyways.

Whaleman (author)Aar000n3y2007-08-24

actually, though I agree with you that these are pretty useless, knex pieces could put your eye out, a 6mm bb can, so a knex rod going at half the speed but twice as heavy should do the same thing. Seeing as the rods go about 100fps, about a fourth of some high power airsoft guns, but are ten times as heavy as a .28 gram bbs that are fired from said airsoft gun, then they should, in theory, put out your eye. Eyes are very sensitive, which is why you can lose sight just by looking at the sun.

Aar000n3y (author)Whaleman2007-08-27

Bbs are certainly not .28 grams. That's way too light for any bb. Even if they were that light, a 3 gram object wouldn't hurt your eye at 100fps. I doubt they even go that fast.

shawbob (author)Aar000n3y2011-03-05

wtf do u mean "I doubt they even go that fast. " theres a limit at my airsoft site of 500fps meaning there are guns over 500fps, my fully automatic one shoots at 360fps. 100fps isnt really that fast anyway, we were over a frends tryin to catch bbs going 80fps with a few catches.

Whaleman (author)Aar000n3y2007-08-27

whoa, 100fps is slower than the crapiest airsoft gun there ever was, some of the airsoft guns go as high as 480fps. And airsoft bbs go as light as .12 gram bbs.

Proof on the FPS

Fricai_Andlat (author)Whaleman2008-09-04

there is no way that knex bullets go 100fps. i built the moretti recon kit gun (what's his face....good gun anyways). i took out any semi auto and made it a one shot. Really good rubber bands. it went 75 feet. took it about 4 seconds. thats less than 20 fps. but yeah, knex could hurt you. could kill you if it hit the jugular at close range too...hehehehehe

Whaleman (author)Fricai_Andlat2008-09-04

But you have to remember, the force is the energy times the mass, so .12 gram BB at 100 fps verses a 4.8 gram Knex rod at 20 fps, which is faster? The Knex goes 1/5 the speed, but weighs 40 times as much. Ergo, the knex has 8 times the power. Of course, if you really wanted to kill someone, then you may as well just break their neck, grab their neck, etc. Humans are fragile.

Aar000n3y (author)Whaleman2007-08-28

I wasn't talking about actual guns, I was talking about the knex rods.

Whaleman (author)Whaleman2007-08-27

BBs Sorry, I thought I had put this on the other one

Sypran (author)Aar000n3y2007-08-23

ok dude AarOOOn3y take a knex pistol (a very strong with sharpend bullets) and have a freind aim for you eye 15 ft away from you a perfect example would be that sniper rifle that turkish guy made it breaks CDs like tisue... oh and conor1148 have the shot shot in you moulth u might choke and die due to it lol.

sdfghjklhgfdsdfg (author)Sypran2009-09-04

ummm pretty much any gray sharpened rod with destroy cds out of even the crappiest of guns

Sypran (author)sdfghjklhgfdsdfg2009-09-11

-___- not if the gun makes flailing bullets, or has like very weak/not many ruber bands

altaria1993 (author)2008-04-04

(PLEASE TAKE CARE, WEAPONS AND GUNS ARE DANGEROUS!) Hmm, isn't that the whole idea behind weapons? (and guns are weapons by the way).

when he says weapons, i think he means like a sword, or a knife, or a chainsaw, or a pipe, you get the point.

So? that does now change the whole idea behind weapons and that guns are still weapons.. also a chainsaw is not a weapon, its a powertool..

blind4life21 (author)altaria19932009-02-21

it can be a weapon in the wrong hands

shawbob (author)blind4life212011-03-05

it can be used AS a weapon, does not make it by definition a weapon

shawbob (author)altaria19932011-03-05

yeah, a weapon is something that is purposely designed to do damage or kill people. Im sure the people at black n decker wernt thinkin of how their chainsaws could kill people better.

NatNoBrains (author)2011-01-04

Safety goggles...
Shoot right through 'em.

good idea, it pays to be safety conscious. but cant a rod penetrate or buckle the glasses? My first time, FIRST COMMENT!! :P


Furloy (author)sdfghjklhgfdsdfg2009-09-27


well i dont want to try it but it probably could from close range, i use a grey rod with a art on the end for ammo so, yes, probably

sdfghjklhgfdsdfg (author)albf12009-09-04

u mean definitely !!!!!!! green rod would buck them

andrew13 (author)2008-08-05

what the heck? KNEX? who still uses those?

ou dont dis knex

charlie farthing (author)2009-09-19

my guns will shot throught that that make so that are stronger

Sting Teddy (author)2009-07-03

If your going to wear googles which I do when shooting at and being shot at with friends... just wear safety glasses.

Stratles2 (author)2009-07-01

why dont you go to sports authority and buy hunting glasses.... or buy a airsoft gun or paintball gun

jakezcop (author)2009-05-20

who, why did you really honestly bother to make those, let alone make an instructable on them....

Rorbob (author)2008-09-13

knex guns can be harmful but they are fun you should really wear goggles

blind4life21 (author)Rorbob2009-02-21

get some airsoft and a paintball mask much better

bannana inventor (author)2008-06-14

If you haven't already post the gun in "picture 2" it looks pretty cool.

bannana inventor (author)2008-06-14

This would be an awesome idea if you wanted to get creative, but a pair of sunglasses would do just fine if you are worried about that kind of thing.

!revenge! (author)2007-08-17

well i think it is a very good idea i shoot myself in my eye that hurt :(

Killa-X (author)2007-08-15

hey people lighten up. if you shoot ammo like me, you need to take care of where you aim. I pin-sharpen mine and use killer-Ks 200 ft gun. I shot a 2 inch ficken hole in the wall...

noik (author)2007-07-31

Dude, Dot you think you can be killd by a knex piece!!! Aaaaaaah!!!!

conor1148 (author)noik2007-08-02

you probably cant be killed, but a flying knex rod at close range can pierce an eyeball (yes, pierce). especially since people are maknig these guns more and more powerful. i use my paintball mask from when i used to play competitive paintball at tournaments and such, i still have my very nice $100 mask (empire e-vents if you know what im talking about) and use my old scratched up lenses that i dont trust to play paintball with, it works fine and is very comfy.

Mad Cat (author)2007-07-10

I dunno, seems a bit stupid...

albf1 (author)2007-07-10

Andy tht sounds horrible, i tryed to use swimming goggles but it made my vision blurry and i hit a lamp....

!Andrew_Modder! (author)2007-07-10

cool,also i was thinking about making some for my airsoft gun, but i forgot my custom 450fps gun went threw a test pair of commercial goggles(so mabe this would not be a gr8 idea for me) :-P .
