Around 2:50 when you shot the fish tank with the sodium dowel: My first thought was: "Just tape an ampoule of cesium to the end!" While sodium does go boom in water, it can take a couple seconds if you toss a chunk into water. Cesium goes boom INSTANTLY. Then I thought a little more and realized cesium sells for $100 per gram. But, I guess potassium is good enough. Sigh.
@@rdizzy1 yeah, it's ridiculous for 2 people to put hours of their time, hundreds of their own dollars and film it with thousands of dollars worth of gear to expect revenue. I mean, making trending shows how many people UA-cam got to advertise to while passing none of those profits on to the Backyard Scientist. Good point.
It is simply the fault of capitalism, UA-cam values the overall money and opinion of the advertisers more than what many content creators think about the situation, because they believe that will net them the most money. So, they put whatever the corporations want into the algorithm and it tags videos accordingly. Unless you think people have some inherent right to post videos and make money off of the back of a private companies servers and brand name, which they don't, not even close. They are free to attempt to compete with UA-cams almost complete monopoly over video uploading service.

Well I already know the first big news story of 2019.. "A man shows us how dangerous tablesaws are by exploiting one of it's design flaws and making it into a fully-automatic weapon"
For those not already aware, the sodium and potassium themselves are not combusting. Alkalai metals chemically react with water producing hydrogen (the actual fuel) gas as a product. This reaction is exothermic and the hydrogen is ignited from the heat released. I'm sure most of the viewers know this already, but some might not and could be (understandably) confused. Cheers.
John Deininger I had no idea of the specific chemistry behind the reaction, that’s very interesting! For some reason, I suppose I always thought they just reacted with water to make a big explosion, and never thought that deeply about it. I feel like most media that uses sodium, potassium, or cesium to react with water just says, “this stuff go boom when touch water”, and I just kind of accepted it. This comment deserves more likes, and it’s been 8 months already, but I hope you’re doing well! UA-cam comment sections need more intelligent, helpful people like you. I hope you see this, and I think we might be good friends. Cheers!
Sorry to inform you but your table saw cannon is only semi-automatic at best. Miss information like this can get my table saw mis-classified and eventually banned.
"Saws are dangerous so be safe when using those, also I'm going to stuff this piece of wood with sodium and launch it with this saw gun" - Backyard Scientist 2018 "Did I mention its full-auto now?"

Every time he turned on the saw, I had to turn down my volume otherwise I would have to awkwardly explain that i was watching a guy throw wood through a pipe
Please shoot this into a ballistics gel like you could do a collab with zombie go boom or something it would be absolutely sick. Like so this gets seen
that what i was thinking of, if you need a makeshift gun in a zombie apocalypse, that would've been it or course it's important to note that a saw table needs a lot of power to stay on, so it's best to use it when you don't have any "metal" ammo left to use against zombies.

Did anyone else notice the sound of the 'Fully-Automatic Table Saw Cannon' shooting at 7:11 is the same sound as the balloons popping in Balloons tower defence
You should find a way to add rifling! Those small dowels fired wonky and I’m curious how much of a difference rifling or making the wood more aerodynamic might make🤔🤔
I don't think rifling would work with a singular saw. Now if you could arrange 3 or more in a diagonal the would would spin like rifling. Rifling works best in guns, because your bullet is still gaining momentum while going through the rifling. Otherwise rifling would just cause massive drag slowing the projectile. Edit: actually just placing the saw offset in the tube and at an angle should spin the tubes as they go through the saw.
You can see the dowels are right behind each other when they're flying through the air. They are being pushed down the magazine as efficiently as possible.
Ok, so you shot Randy with the tablesaw but why didn't you shoot him with a pointed tip? Why weren't there any experiments with pointed tips? We know that, the moment you made one with a pointed tip, it went STRAIGHT through metal! Would love to see Randy's reaction to a pointed tip spearing through him. Also last video, many of us asked to try ballistic Gelatin, or try to see how many sheets of metal it could pierce (With the pointed tip of course). So, there's still tons of ways to top the fully automatic cannon.
