Nerf guns are one of the most fun toys out there, whether you are playing target practice or having a battle with your friends. Engineers have been known to heavily modify Nerf guns to make them more powerful or maybe just a little dangerous. However, one former NASA engineer turned Youtuber has taken things to the next level and built the world’s largest Nerf gun that can launch projectiles over 100 meters!

This trio of engineers built this insane replica Nerf gun using a compressed air system built into the perfectly scaled-up Nerf shell. Using a typical 3,000 psi compressed CO2 tank you can buy for paintball guns, the team rigged it up to a regulator valve triggered by, well, the trigger. Pushing the trigger forward fills the firing tank, and pulling the trigger back, fires the giant Nerf bullet projectile. Each launch uses 80 psi of compressed air, which is plenty to send the pool noodle and plunger darts flying.


The internal mechanism of this giant Nerf gun is actually pretty simple, and you can get a decent idea of what you need to design to make everything work in the video. Having a giant Nerf gun seems a little impractical, but when it looks this cool, it is definitely something you need. This gigantic gun is the perfect combination of awesome engineering and insane fun.

So, now that you know it’s possible, gather up all of your friends and build an arsenal of giant Nerf guns for the most intense, yet safe, battle ever!

  2. Hurrah, that’s what I was searching for, what a information! existing here
    at this web site, thanks admin of this web site.

  3. I must say, as substantially as I enjoyed reading what you had to say, I couldnt help but lose interest after a while. Its as if you had a excellent grasp to the subject matter, but you forgot to include your readers. Perhaps you should think about this from additional than one angle. Or maybe you shouldnt generalise so much. Its better if you think about what others may have to say instead of just heading for a gut reaction to the topic. Think about adjusting your very own thought process and giving others who may read this the benefit of the doubt.

  5. Awesome post! I’ve been trying to come up with a good internet business idea for a while. Instead, I have come up with a great non-internet business idea, which kind of sucks in a way because this idea requires a lot of money, as opposed to a full internet-based business that might not require that much to get it started. I’m not giving up though. I recently started a blog where I plan to document my steps for starting my company. I figured it would keep me motivated and force me to keep at it. I also hope it will motivate the readers to keep trying to accomplish their goals. By the way, I love your site. I’ll be adding it to my list of interesting blogs.
