Making the real life version of Katniss' bow from The Hunger Games is impressive

No one can bring weapons from fictional worlds into real life as well as the crew from Man At Arms: Reforged. The blacksmiths are just too good at what they do. This episode of the making of Katniss’ bow from The Hunger Games is especially cool because you get to see a big block of aluminum that weighs 19 pounds get… »11/16/15 8:00pm11/16/15 8:00pm

How the US Air Force reloads the largest combat jet gun on the planet

When you got one of the biggest guns in the world, you can’t just pop in a new magazine and start firing again. Well, you can but the new ‘magazine’ for the GAU-8 Avenger is so ginormous it needs to be trucked in and requires multiple Air Force guys to get the gun reloaded. It takes time to get giant bullets on board!… »10/13/15 3:20pm10/13/15 3:20pm

The 40th Anniversary Python Holy Grail Box Set Doubles As a Working Catapult

It’s hard to believe that the greatest achievement in comedic filmmaking is already 40 years old.

Making a katana the old traditional Japanese way is so impressive

I think this is the most impressive video that Man At Arms has ever done, and that’s saying a lot since they’ve recreated all the coolest weapons from TV shows and movies in real life. But there’s something ridiculous impressive about making a katana (stylized like the one from Kill Bill) the traditional old school… »7/14/15 2:38am7/14/15 2:38am

Which of Our Favorite Sci Fi Gadgets is the Most Powerful?

San Diego Comic-Con is in full swing, so naturally, we’re seeing a lot of iconic scifi gadgets this weekend. But as a faithful Giz reader, if you’re in the market for a fantastical new weapon to defeat your sworn enemies, you’re gonna want specs.

What It Feels Like to Shoot With the Military’s Experimental Smart Scope

You’ve probably never fired an M4 carbine. Until a couple weeks ago, I hadn’t either. But at a recent DARPA demo day, I loaded a magazine (also a first for me), snuggled up to the deadly assault rifle, and looked through one of the most technologically advanced smart scopes ever built. Then I pulled the trigger. »4/29/15 12:09pm4/29/15 12:09pm

Trying to Make Game of Thrones Valyrian Steel Sword With Real Materials 

Nothing reigns consistently in HBO’s Game of Thrones (and George R.R. Martin’s “Song of Ice and Fire” book series that inspired it) except Valyrian steel, a magical sword material. Valyrian steel is, of course, extremely not real. But materials scientist Ryan Consell took a look at its chemistry anyway. »4/07/15 12:07pm4/07/15 12:07pm

The Computer Simulation That Almost Started World War III

Remember the 1983 movie WarGames? The film is about a computer "game" with the potential to start thermonuclear war. But strangely this scenario is more truth than fiction.

The Navy's ship-mounted laser cannon has been a long time coming, notes Brian Resnick, who chronicle

The Navy's ship-mounted laser cannon has been a long time coming, notes Brian Resnick, who chronicles the 50-year history of the military's "dream" project. "The LASER may be the biggest breakthrough in the weapons area since the atomic bomb," the head of the Army Ordnance Missile Command wrote in 1962. »12/15/14 1:41pm12/15/14 1:41pm
