So we painted the cannon. We did some low pressure testing, which I'm sure the neighbors blamed on
0:03:51 - 0:04:01
If we pull that rod back, it'll break the seal, dumping all that air behind the baseball and off she
0:03:55 - 0:04:05
dumping all that air behind the baseball and off she goes.
0:12:16 - 0:12:25
But the shockwave is going to come out, and the baseball, at some point, is going to outrun...
0:14:17 - 0:14:31
(Destin) We got baseball. We've got... we've got ideal gas law.
0:01:04 - 0:01:13
This is me in a German air cannon.
0:04:19 - 0:04:29
that force to try to pop the cork on the baseball even faster.
0:04:25 - 0:04:35
And then we compress that front gasket, making a seal behind the baseball.
0:10:09 - 0:10:18
if we can see the shockwave go across and the shadow graph of the baseball.
0:12:46 - 0:13:02
Let's get a baseball. [exhaling excitedly] It's time. It is time.
0:17:32 - 0:17:41
So as the baseball goes across, not only can we get velocity this time, we've got a really good pixel
0:17:36 - 0:17:47
we've got a really good pixel calibration and we'll be able to get the drag coefficient and the baseball
0:19:22 - 0:19:33
the cannon was extremely consistent with its targeting.
0:00:50 - 0:00:58
I thought about the ballistics of throwing a baseball through the air.
0:02:01 - 0:02:11
The baseball is 1.6 times larger than the golf ball and three times as heavy.
0:19:14 - 0:19:27
After several shots, we realized the cannon was extremely consistent with its targeting.
0:00:24 - 0:00:34
What happens when a baseball goes past the speed of sound?
0:09:51 - 0:10:03
Today is the day we're going to shoot the first baseball in a relatively controlled environment.
0:12:02 - 0:12:11
however many weeks it takes to get the exact shot I'm looking for, which is a shockwave over the baseball
0:18:39 - 0:19:14
Narrating) We've all heard the expression "knocking the cover off the ball", but the ability of a baseball
0:20:41 - 0:20:55
The crazy idea is: what if I get a baseball with a
0:22:56 - 0:23:07
And I will send you this baseball.
0:23:01 - 0:23:11
I need to know your address, because I need to send you your baseball because I have it.
0:05:06 - 0:05:16
With the golf ball cannon. When we looked at the slow-mo,
0:01:43 - 0:01:52
we made a golf ball air cannon.
0:04:15 - 0:04:25
thing, but it's actually good, because we're going to use that force to try to pop the cork on the baseball
0:04:47 - 0:04:59
And then we release that sear and it'll dump all the air into the baseball. So it goes stupid fast.

time to load a baseball I forget how tight that is all right we put the plastic over here just so we
0:11:48 - 0:12:12
how you get ants three two one oh there's the baseball all right I got it I do so much happening right
0:00:16 - 0:00:28
make a baseball go past the speed of sound and we can 1050 miles an hour Mach 1.38 so now it's time to
0:09:13 - 0:09:22
and so we Define the baseball curve out here there's something funny about writing out zero to two thousand
0:09:25 - 0:09:36
we're trying to get all the data here so we can get the complete drag of a baseball can I please see
0:25:28 - 0:25:42
a jar of mayonnaise with a baseball at a size and 74. yes now we know obviously that question has been
0:03:35 - 0:03:44
shoot the cannon we're going to get the velocities as a function of pressure and we're going to see what
0:03:24 - 0:03:35
in here yeah look at that so you can see where the baseball hit last time that's cool we're gonna be
0:04:02 - 0:04:15
that first shot no target just camera check out got a checklist today on the phone time to load a baseball
0:09:09 - 0:09:16
yeah so what I need to do is I need to draw one of these and and go out here and so we Define the baseball
0:18:08 - 0:18:20
it we need to move that way move it up oh wait I can move the mayonnaise we need to move the whole Cannon
0:09:46 - 0:09:58
this is not a spinning baseball this is a knuckle ball okay it is time for the first smarter everyday
0:01:08 - 0:01:17
what we can do with a baseball the way we're going to do that is we're going to characterize this thing

This is the cannon image or something. What is it? Trent: Me20F-SH Destin: OK, all that.

Like last year we built the super sonic baseball canon. This year. My dad worked on the James.
