Konigstrasse at UAH that a bullet travelling in the transonic regime can create supersonic flow around

don't know a t-38 is that is the supersonic trainer for both the Air Force and NASA and it is awesome

from before that from zero to 600 miles an hour has been done and I'm assuming that was a spinning baseball
0:03:31 - 0:03:38
able to aim much more accurately now okay so this is the goal we're going to shoot the cannon we're going
0:12:07 - 0:12:24
happening right now all right this sprinkled slowed the baseball down okay we didn't have a vacuum oh
0:03:10 - 0:03:20
removed before firing what we can do with this is we can look down the shot path of the cannon and we
0:00:11 - 0:00:21
what have we done look at it we initially just wanted to see if we could make a baseball go past the
0:02:17 - 0:02:27
do with this is we're going to look at the overall View and as the baseball comes out here we're going
0:08:56 - 0:09:08
miles an hour so we just defined the drag coefficient of a baseball from 917 miles an hour to about 825
0:27:27 - 0:27:33
subscribing if you'd like to see that also if you'd like to be a patron I'd love to send you a baseball
0:27:30 - 0:27:36
love to send you a baseball like this and if you have been a patron for a while I've got something cool
0:03:15 - 0:03:24
path of the cannon and we can aim in terms of inches now that's really cool so I don't know if I can
0:01:04 - 0:01:12
is for a smooth spear this is done by a guy named Wesson we're going to see what we can do with a baseball
0:06:21 - 0:06:30
travels now and we know how much time is in between each frame we can get the actual speed of the baseball
0:06:25 - 0:06:39
the actual speed of the baseball it was going 917 miles an hour oh we can chart data now oh where's all
0:25:20 - 0:25:33
thank you 1.4 Mach 1.4 1 2 3 4. so that's what happens if you hit a jar of mayonnaise with a baseball

Hey, it's supersonic. That was Mach 1.35. I mean, that's just measured straight up with poles.
0:21:18 - 0:21:29
Which is why I reached out to the new minor league baseball team in town, the Rocket City Trash Pandas
0:00:43 - 0:00:54
threw the first recorded baseball past a hundred miles per hour.
0:02:47 - 0:02:56
And we may be able to get supersonic velocity with air just because of the vacuum here.
0:01:09 - 0:01:18
This is me in a German air cannon. Anyway, here's the deal.
0:00:39 - 0:00:48
And I learned that in 1974, Nolan Ryan, while playing for the Angels, threw the first recorded baseball
0:17:29 - 0:17:39
So as the baseball goes across, not only can we get velocity this time,
0:20:47 - 0:20:57
The crazy idea is: what if I get a baseball with a Smarter Every Day logo on it.
0:01:34 - 0:01:47
[Guitar theme music] In an earlier episode of Smarter Every Day, we made a golf ball air cannon.
0:05:10 - 0:05:18
With the golf ball cannon.
0:00:30 - 0:00:38
This is a Smarter Every Day baseball, by the way, more about that later.
0:01:24 - 0:01:34
I have to know what happens when a baseball goes past the speed of sound.
0:04:31 - 0:04:42
making a seal behind the baseball.
0:19:08 - 0:19:20
but the ability of a baseball to be destroyed by literally ripping itself apart with kinetic energy is
0:22:50 - 0:23:01
And I will send you this baseball.

And by the time we pressurize the cannon, it would droop down off the bottle we were using to hold it
0:17:25 - 0:17:35
hoping to bounce more of the Sun's light back up to the baseball.
0:00:45 - 0:00:55
And now I'm at that critical point where I want to start characterizing the cannon and how it works
0:01:06 - 0:01:15
continuing our mission to graph the relationship between how the amount of air we jam into the cannon
0:00:18 - 0:00:28
that'll shoot a baseball faster than the speed of sound.
0:01:09 - 0:01:19
between how the amount of air we jam into the cannon correlates with how fast the ball goes when that
0:13:23 - 0:13:47
We are now at the highest pressure this cannon has ever seen. 800. You ready? Ready. 54321 fire.
0:00:21 - 0:00:31
massive undertaking that's honestly, really kind of like the cumulation of my childhood love of baseball
0:17:30 - 0:17:37
we expect the baseball to fly through sunlight twice in the rest of the time.
0:00:39 - 0:00:47
This cannon was a beast to design and build in the patrons of Smarter Every Day paid for it, for which
0:01:48 - 0:01:58
We only need like the first 30 feet of baseball flight for scientific purposes,
0:16:37 - 0:16:45
What we want to do is see a reflection of the baseball over here to the side, which means we can set
0:16:56 - 0:17:07
In fact, you can see the reflection of the sunlight on the ground there as the baseball gets closer
0:03:28 - 0:03:35
And because it's not safe to be down range with pressure on the cannon, we had to improvise an odd little
0:13:19 - 0:13:27
We are now at the highest pressure this cannon has ever seen. 800.
0:00:55 - 0:01:06
The ability to precisely control the velocity and timing of a baseball will let me do all kinds of
0:16:59 - 0:17:11
there as the baseball gets closer and closer to the mirror.
0:17:37 - 0:17:50
We've got the cannon shooting to this mirror bouncing back here to this camera lens.
