You’re up. People have these Nerf Dart wars at work sometimes, so in an effort to keep people from picking on me, I decided to create the world’s largest functional Nerf gun. So, I reached out to a couple of fellow engineering nerds, Ryan and David, from the Youtube channel Eclectical Engineering to see if they’re up for the challenge. So, it’s one thing to look good, but let’s see how she holds up against the guns of my co-workers. So here’s how it works. So the source of the air is this 3,000 psi paintball tank. By pushing the trigger forward, you let the air into this firing chamber here. And then, when you’re ready, you can pull it back to let the air out into the main cylinder and fire a dart. So, the paintball tank starts at 3,000 psi, but the silver chamber is regulated to only 80 psi for shots. By doing it this way, you get about 20 shots out of a single tape. So, after you shoot, you just rotate the cylinder over, and you can do it 5 more times. The darts exit the gun at about 40 miles per hour. And they’re made of pool noodles with toilet plungers on the end, which means they can actually stick to things. So, you can use it for skeet shooting, or Dude Perfecting. We also 3D printed a projectile that was a little more aerodynamic. And we were amazed to see it travel 130 yards. Wow.. So, I wanted to see if this thing actually worked in real life. And as usual, my niece and nephews were picking on me. So I challenged them to a Nerf dart war. Only, I may have neglected to tell them about my creation. So, a huge thanks to the brains and muscles of Ryan and David for helping to push this project to completion. They actually made a video on their channel of everything you need to know to build one of these for yourself. We also made some modifications to the Nerf gun to make it possible to absolutely obliterate watermelons. So, go watch that, and subscribe to their channel, because they’re kind of new, but they got some really cool videos in the works. I also want to say thanks to Audible. So a couple times a week, I will sit right here in my backyard, and sort of just look at the sky, and think about whatever. And it always makes me smile when I think that one of the dots 50 million miles away, has stuff on it that I have touched and designed. In fact, of all the videos that I have made, my favorite one is the one where I talk about what it felt like to see Curiosity land. [Inaudible] So, Rob Manning was the chief engineer for the Curiosity Mission, and he wrote a fascinating book that I just finished listening to, that gives a perfect overview of how Curiosity succeeded against crazy odds. He’s a really smart dude and a great storyteller. So, if you want to learn how NASA puts robots on tiny dots in the sky by listening to Rob’s book, or if you want to listen to any other book for free, all you have to do is use the link in the description, or go to Thanks for watching.

  1. That thing can be used as a weapon of war if the right modifications are made, such as:
    1. Switching out the toilet plunger ammo to actual shells
    2. Increasing PSI per shot

  2. Alternative title: shooting giant nerf plungers at 40 mph at my neices and nephews for picking on me

  3. Nobody needs or should have a Nerf gun. I don't know why people think they should have them. ONLY the Police and the Military should have them, not the citizens. Nerf Guns are Bad. You don't need more 3 rounds to protect yourself from Bad guys-5 rounds are too much and encourage mass Nerf shootings.We don't need anymore Mass Nerf shootings. They all should be banned or a Nerf Buy back program for Food Stamp Cards. STOP! the Mass Nerf Shootings and write your Congressman. Join "MANS" ( Mothers Against Nerf Shootings). Get out and protest against the use of Illegal Nerf guns. Ban the Nerf Bumpstock, Suppressor and 30 round Nerf mags. Fight against the NRA (Nerf Rifle Association). We don't need the Nerf Amendment,we should just get rid of it. I can't believe YouTube's Advertisers find this video's content suitable for their Ads. I can't believe this Pro-Nerf Channel hasn't been banned for promoting the sale of Nerf Products. Don't forget about the Nerf show "Loop-Hole where people can buy them without a Backround check and you can buy as many as you want off of the internet. Nobody needs or should have an "Automatic" Nerf gun. Take the Nerf Guns Now and worry about Due Process Later. I'm just sick to my stomach over all of the Nerf Shootings out there today, It's got to stop.

  4. Creds to eric heiner for the comment but i agree with him
    My favourite part is how when the nephews see the gun, they instantly know that it works

  5. Me:trying to build a JSBP gun
    Takes me a whole summer

    Rober: making a nerf gun
    Takes like what 3 second to build

  6. Did anyone else hear a halo arena announcer say "Overkill" in an overly dramatic voice when something got hit by his op nerf gun

  7. I made a smaller version of this and shot it at my brothers head and I cracked his head….

    The hospital bill was $2,350……

    Sorry mom and dads bank account………

  8. Wait, if you got hit with one of those bullets, would it be like getting hit by a car, considering it goes a little faster than an average speed limit?

  9. To everyone saying that 40mph is too fast and can hurt people, I get shot by airsoft bbs going at 260 mph on a regular basis
