How to Make a Mini Dart Gun w/Multiple Configurations

[@GreekGadgetGuru]

Interesting! Would make a decent wrist launcher if you attached it to a brace. This really helps me understand the piston valve, Thanks Ben!

[@isaacsilver4901]

that's what I was thinking/and now doing

[@SteveSmith-fw3uo]

Super late on this but... Has anyone tried firing this set up via hitting the center pin on the air valve where the pump attaches?

[@HybridLibrarian]

Amazing job! That was a cool and very elaborate project.

[@kipkedersha5604]

Now THAT is one sweet Dart Gun!

[@Odood19]

I'm seeing many of the people I'm subscribed to in the comments! You're one of them.

[@Odood19]

***** Kipkay has videos. Superior logic.

[@eunjunshin9540]

O_O OMG

[@Xilver_]

***** that is not actually kipkay because he hasn't changed his KZbin channel name, has over 1 million subscribers and has a lot of videos unlike the guy whos trying to copy him

[@mismag822]

That was fantastic!!! Great tutorial!

[@zdf46]

Cooper Ruberti no

[@kimtuyennguyen80]

Experience these require too much technical equipment. Could you do the same kind of weapon but with recovery of materials? As school equipment.

[@shishKababGamers666]

You could also try to add a loading system where you slide a larger piece of pipe over an open port in the barrel. Or even add a Co2 capsule w/ a bike filler valve which could be easily concealed. Endless possibilities! Great video man!

[@alltime10s]

Cool

[@misik52]

Omg its you

[@zdf46]

***** they are all spam channels begging for more attention because they don't think they have enough already...

[@Scotrik98]

zdf46 Alltime10s has over 2.3 million subs so I dont know what you are talking about...

[@MrDagassman]

Anti Scotrik I think he makes a good point. I've always wondered why this big channels make simple comments like this and it may be just cause they're interested but it would be a good way to draw more attention to their channel.

[@eunjunshin9540]

OMG LOVE YOUR VIDEOS

[@girrrrrrr2]

You are becoming the new Kip Kay. Only more badass.

[@notpumkin]

Agreed.

[@REALGAMER29]

:D

[@ryanhadfield8866]

Yet another fantastic project from NightHawkInLight

[@francescoquadrio5824]

im happy you are back with diy... i missed it

[@jcims]

Awesome video!!! I love this idea, the final result looks great! One thing that occurred is that you could fuel it via electrolysis, maybe using a little pvc 'grip' that has the water/electrodes/battery in the handle. A buddy did this with a little film canister noisemaker and it was surprisingly effective.

[@Nighthawkinlight]

I really like that idea, maybe something for a later video. Thanks!

[@Punisher97]

Make another project with these soda bottle preforms Really enjoyed this one, trying it myself now :)

[@troyna77]

dude! every single step in this video reflects intelligence and simplicity in manufacturing. i would want to be on your side when the zombie Apocalypse occurs. your camp would be packed with cool weapons and machines !!!

[@josephmelnick3446]

WHAT IF... rather than twisting the cap to release the pressure on the back of the piston, you depress the pin on the Schrader valve with a trigger/lever gizmo. More gun-like. Less twisty. More aim-y. The trick is leaving the S-valve open for charging while subsequently letting the pin/trigger mechanism to move into place to allow firing of the fry. Make it so!

[@clangerbasher]

It is never the science as such I find interesting with these projects it is the materials. What can you get? And what fits with what? etc. etc. For example I didn't know you could get those preforms online. Wonderful video.

[@miranaser]

Great video! Quick question please, with the isopropyl alcohol, do you spray each time you fire, or will one spray last for multiple shots? Thanks!

[@Nighthawkinlight]

It's possible that one spray will last for a few shots if it coats the walls, but no matter what the camber needs to be opened between shots so fresh air can get in.

[@TheChineseUnicorn1]

Your voice makes me happy

[@iPwnSauce]

You sir are gifted and should sell such devices. I for once am willing to throw my money at you. Great job!

[@nmarks]

Like Bro Brah said, what's the range of this gun? (compressed air and alcohol)

[@BrutalRandon]

this channel is life

[@suivzmoi]

better trigger for the piston version is to use a small cap (use the bicycle valve fitting cap with threads sanded off) with a pin epoxied in it and use that cap to depress the pin valve on the schrader fitting. that should be enough to pilot the piston, and also allows you to use the gun with one hand :)

[@Alan_Hans__]

I have used tyre valves from car tubeless wheels for the same style thing. All you need to do is drill the right sized hole and pull/wriggle the valve into the hole. Fitting it inside the piston should still be achievable. The cap and blanks should be good for 100psi or more so providing the rest of the build is done well you could get some serious oomph out of it.

[@TheJonesChannel11]

I always love your projects.

[@ryancl03]

hot glue would work over epoxy as well. I have used it in the past to seal various high pressure projects. would probably be a good idea to rough up the surface you are adhering the epoxy or glue melt to.

[@AbhinavSubramanian]

Just bought some plastic test tubes on amazon to make this. Looks pretty darn awesome.

[@TheMrSalu]

Nice job, greetings from Brazil.

[@CarbonPrey]

Nicely presented video's. Clear, a good pace and easy to follow with some great ideas.

[@interplexer]

This is indeed a nicely made vid. The air compressed option seems the best, ... Great job NightHawkinLight

[@SeanixOnlineGameing]

Really cool dude. I like all your Projects. Keep It up man

[@nickieisyoppie]

Dude your videos are SO COOL!!!

[@DRTWerks]

Hey, Im wondering if you could use the coaxial piston valve with a full size 20oz soda bottle it the same way or if the pressure differences would cause it to act differently?

[@Zayn873]

1:90 What a simply and genious design.

[@Niels357]

Nice design!

[@aserta]

One other method to get valves in to caps is to remove the valve itself from the threaded portion. Then, take that threaded portion and heat it, once it begins to melt plastic ( a test piece to be kept close) force the threaded piece in to the cap or plastic surface of need. When cooled reinsert the valve in to the threaded cylinder piece and voila, the perfect sealed valve. Melting the plastic as opposed to drilling it does 2 things. 1. the hole is perfectly formed around the thread 2. the melted plastic sticks to the sides of the thread making it a very secure seal. I've had one such valve for over 9 years. I use it to inflate a re-purposed air shock. It helps me lift the side of a drill press that has no lifting points or recessed areas at the bottom.

[@Nighthawkinlight]

Nice trick, I bet that works great!

[@GoldenBoy-lv1jg]

NightHawkInLight What do you call those plastic test tubes that are the same size than soda bottles?

[@PetrifiedPotatos]

Nice video. Will any soda bottle preform work? What's the maximum PSI? I know the one you suggested is 60. Also where did you get your preforms?

[@Nighthawkinlight]

Yes, any soda bottle preform should work. 60 psi is a good working pressure. The preforms can stand hundreds of psi, but the caps cannot. I broke several of them pushing it up to 100.

[@taka2va]

It would be cool to make a semi-automatic version by placing circular metal contacts on the caps (with the same configuration of wires on the inside) and making one trigger that can fire them. Essentially seperating the trigger mechanism from the projectile.

[@GoRepairs]

Great video Ben! What versatile little design. :)

[@CaptSumTingWong1]

I just skimmed over your channel and it look pretty good so I subscribed, dont let me down!

[@ground5quirrel470]

[@PHEOBEPARADISE]

Thanks for sharing this nice video :) Does it need to spray the gas before shooting every time? If not, how many times? Besides, can I spray more in it once so that I don't need to spray it that often? Dose it generate high heat while shooting? degree? (or it is too short time to have much difference ?)

[@dylanpeel6315]

where are you getting the soda bottle preforms from i am assuming they should be very cheap but looking around the only one i can find for the proper price (around 2 to 3 cents ) is on orders of about 100,000 i can find a pack of like 5 for 5 dollars but it is still not very good where do people get them from

[@dumuzi5538]

Awesome video! You always have sweet posts. Thank you. The sodium video's are my favorite ones because I use elemental Na for my experiments and I'm pretty sure we are witnessing low energy nuclear transmutation with the magnesium/sodium hydrox burn. You the man! Love and blessings to you. Namaste.

[@HandlesLikeADream]

Nice tutorial/project. Subscribed!

[@mohamedessa627]

I have almost watched all of your videos and i have been having some issues finding the equipment to do your projects so can you tell me where do you get them in your next video or why do not you buy them and sell them online for a higher price

[@cphVlwYa]

If you did the end of the dart in alcohol will it light as the alcohol vapor combusts and shoot a flaming dart?

[@CaptSumTingWong1]

Dont want to sound dumb, but do those lighter spark things ever stop working, like they have no batteries and generate their own electricity right?

[@k-rodkev-dog7449]

Im pretty dure that they generare their energy

[@Nighthawkinlight]

They will get weaker after a lot of use until they eventually break, but they don't have a battery that drains over time. They make an electrostatic spark by striking a crystal which creates a misalignment of electrons between the positive and negative wire. I think it's probably science but it could just be magic.

[@arthurjaspar573]

nice one man better than the first one

[@jackmehoff6767]

I wonder, what would be the range on this dart gun. Also it would be great if the air could be released with the push of a button so as to make the aim more sturdy without a vice grip.

[@tigerwild8153]

How far will it shoot? If it doesn't shoot any farther than in your video, how would someone adjust it to shoot 20 to 25 yards?

[@sunnysanders2478]

hey nighthawk another question do u have to hold it in place like u have it in the video or can u free hand it and which is more powerful to u the bbq lighter or the pressurized air

[@djpendejo9258]

Can Axe/Lynx be used instead of alcohol? Or will that just create a boom?

[@adamurmos9270]

Awesnome project as always. But sometimes finding the correct items can be very difficult if you are not in the US. Any idea about where to buy brake lines...?

[@Nighthawkinlight]

You should be able to find brake lines in any country that has cars. They're commonly replaced. Auto parts stores usually carry them in stock.

[@JMichellePhillipsRisingthunder]

We seen some of your videos and tried some of them out. Yeapers, they where fun. Thanks fun the fun on a rainy day.

[@jeffgardner8103]

Something else I thought of, I don't know if I could sand rubber. Search rubber bumpers at Home Depot. Most of them have threads or screw holes in them for mounting. If these were to be mass produced, get a cheap flaring tool and copper or brass tubing.

[@Marvel2328]

How would I make this semi-automatic? Also, could I put in a magazine to feed in pellets?

[@er1cdoom]

NightHawkInLight, is it possible to mod this to have a larger barrel to fire mini marshmallows?

[@jb280557]

Hi I have to ask on the electric igniter option for the dart gun what did u spray in the barrel?

[@MrTMHTV]

If the tube at the barrel is closed wont it pressurize the cannister until a valve is opened. And im talking about the second design.

[@andrewsmith7693]

Do you think the design with the bbq ignitor could fire firecrackers?

[@andornsshadow]

cool, did you even think about a method to making it able to reload quicker with the igniter? it would be pretty cool

[@FragIsBoss]

Hey man, great video! I've been watching your videos for a while and I've even used your vacuum cannon video for a project for school. I really enjoy watching your work and was wondering if you could do more Chemistry based videos, like with Gallium, mercury, etc.

[@everettdickinson8655]

Where can you get the valve to fill up the preform? I can't seem to find out where to get one.

[@XxXxN27CHAOSxXxX]

I can't seem to find a break line any where. Will aluminium tubing the Sam size work

[@The_Wizard-Jester]

Is there anything else you can use as a combustion chamber the a soda bottle preform?

[@destan5568]

Very good video, it's just what I'd expect from the NightHawkInLight, in a way this is an upgrade over your old barbecue lighter dart shooter, simpler and easier to build.

[@phantomcut1]

How much rubbing alcohol should I put in so I don't blow off my hands?

[@giveaways216]

Is it possible to put this on an angle and fire a larger projectile for a mortar style launch?

[@blackvalley007]

You are so awesome, first the touch shock thing and now this... A well earned subsribe!

[@Flofy387]

Can i have a link for a plastic test tube ? And whats Proxy (the Glue) in german ? :O

[@shlokpanchal6619]

Can we use a plastic tube instead of the steel breakline? For air compressor one?

[@TheTacticalWanderer]

Perfect no one will suspect a thing!

[@marytoney9373]

i wish i had that kind of talent to make things like that

[@xXMrProGamingXx]

Please, no link where to buy? It seems they turn out to be expensive for their cheap value.

[@After_Tech_Industries]

What if you use the butane canister with it's valve and the tube going to the lighter's nozzle to feed the combustion chamber, it automatically pulls air into the chamber if you leave the hole on the side of the nozzle open to air. All to feed the combustion chamber.

[@dragonboyjgh]

Could you presoak the ammunition's cotton end, instead of spraying every time, to speed up reloading?

[@nachoala5105]

does it have to be the barrel you showed on the video?? or any barrel will work?

[@tylercoffey5019]

you should try to make more projects with those preform soda bottles those things have a lot of potential.

[@staciemarie5859]

That's awesome! What a great way to recycle!

[@Stevepilot]

Do you know what psi and how many sprays of alcohol you could use for max power without breaking it?

[@Nighthawkinlight]

+Stevepilot 100psi is probably about the max before the bottle cap will crack. I use one spray of alcohol but that will vary depending on many things.

[@Stevepilot]

Ok thanks and keep up the good work!

[@gr8sl8m8]

+Stevepilot chronograph...

[@samspina3249]

Amazing video as always!!! I can't wait to make one. But does anyone have any idea what sites sell the preforms? I couldn't really find any on eBay.

[@dadisi09]

I'm building this next paycheck. What I really want to design is an automatic pnumatic needle gun.

[@wilson0408]

is it possible to integrate the alcohol source with the combustion chamber in the potato cannon design? so that reload time is reduced or even rapid firing can be achieved?

[@Nighthawkinlight]

No. One way or another you have to open the chamber between shots to let in fresh air.

[@thedococ14]

It's really funny because I actually watched your video where you first made the mini cannon and then the following day I made it with a preform! Two great minds think alike. ;) But one question, mine is really loud and I was wondering if you could make a silencer for it or link me how to make one. Thanks in advance.

[@artifact9118]

What is the point of using that bottle ? Can we use a regular one ?

[@Scorpiofurry]

What is the cheapest airsoft gun/ air pressure powered device you can make? For those of us who dont always have twenty to eighty bucks to spend for each project. Dont get me wrong i am happy compared to other channels your projects seem to be cheapest while still remaining most durable as well.

[@Nighthawkinlight]

I have the perfect project for you. I'll probably make a new video about it in the future because I like the design so much and it's so much fun to use. Check out the $4 bottle gun that I made in this video that fires by squeezing. It works really well: How to Make a $4 BB Gun & Airsoft Flamethrower

[@Scorpiofurry]

cool thank means alot to me and id love to see any cheap modifications you can throw on it as well.

[@hooplan77]

you should try a project with HHO gas which is more powerful than propane or methane.

[@damondholsinger1632]

how mutch fps (feet per second) will it shoot a 12g. 6mm. airsoft bb?

[@ryanmealtimer6453]

Keep up the great work

[@tybo09]

Thanks for another cool video.

[@jameshuang8609]

Where can you get the plastic test tubes, can you get them without going online?

[@Silasssssssss]

Nice, maybe you can gleu some kind of handle to the pre-form with the conbustion version? I imagen that would work insanly well :D

[@michaelpedersen18]

Where did you get the Valve for the air powered cannon? A great project but the rubber and air valve is all i need to finish it

[@Nighthawkinlight]

Google 'air tank valve'. You'll find lots of them.

[@doothowell7951]

thats prety friken cool,man

[@doublextrouble7482]

kipkay made this kind of "QEV valve" gun, but it was fit in a mag lite to give it more of a concealed look. but there are people on the interwebs that also made this "flashlight gun" and they filled it with sometimes more then 300 psi which caused the bb/pellet that was beeing inserted to gain a speed of sometimes between 700 and 800 fps...this is more powerful than a pellet gun/ air rifle (0.o)

[@acciaiomorti]

couldn't it be used as well to fire a small caliber bullet?, and a handle could also be attached, or perhaps the same method could be used with pipes meant for compressed water to create a crude, inaccurate rifle?

[@nicholassciarappa9919]

Could you use hot glue instead of apoxy? Or will that not work. NightHawkInLight

[@everettdickinson8655]

I was wondering, where exactly would you get the brake line tubing? I went to my local hardware store and they weren't sure if they knew where to get it. Anything helps!

[@Nighthawkinlight]

Brake lines are for cars. You can get them at car parts stores.

[@everettdickinson8655]

Thanks! I really appreciate it. Keep up the good work!

[@35Sohan]

Your projects are really awesome but to make the video even more entertaining you can put a song in the background while you explain ^^

[@Volaths]

Damn, that thing really packs a punch.

[@johnseed4104]

is there any thing you can use instead of a pre form

[@AbhinavSubramanian]

Would this work with a 16mm diameter test tube? I think I bought the wrong size by mistake

[@siribiriz]

you reckon you could drill it without getting it to crack?

[@AbhinavSubramanian]

Yep, although I would probably have to use a different size pipe...

[@DezamaruVG]

I am so glad this isn't a prank :D
