Introduction: 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

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

see picture for my reccomendations.

Step 2: 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

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.

    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.

    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.

    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.

    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

    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

    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.

    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.

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

    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..

    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.

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