- Last year, we attempted to cork a bat... and we did a terrible job LOL
• Hitting with a CORKED ...
So today we're giving it another shot, but we're doing it right this time. Let's see how a professionally-corked bat performs!

It’s always been hilarious to me how baseball diamonds almost always seem to be facing a road or area where cars are parked. It never fails
Most non-MLB or MiLB parks are just tucked into city streets so no matter which way the park faces there will be streets
And for basketball, courts usually face the road, or a hill 😂 makes balls that hit the rim a pain in the ass to get
My local field is facing into the woods, but the players foul enough that cars get hit anyways
roads and cars are everywhere man
“Whoa bro we almost hit a car”
*ball bounces and smashes into the passenger side window of a minivan causing a mother to swerve and flip her van with two children inside*
“Dude! No way bro! These corked bats are crazy man”
"apparently that video went viral in the carpenter community"
that had me dying Will
lol
😭😭😭😂
I think to really make sure you control for all variables, you have to have a single blind test. Have someone completely unaware of the differences between the two, then do the exit velo test. If they know it’s corked, they might swing harder unconsciously.
You can feel the difference in the weight of the bat though
That would be a single blind test because the test givers know what's up.
@@lefi75 You're correct. I fixed it.
It doesn’t matter for this. They know exactly which is which when they pick them up.
Completely agree. And, the ball should probably be stationary with the bat swung by a mechanical device.
I remember that corked bat video and now the channel has grown a lot since. Job well done.
Haven't they done scientific studies that this doesn't really help anything?
@@ItIsYouAreNotYour it absolutely helps.
@@kingsolo6241 I'm going with science on this one.
First, they say the trampoline effect is negligible in corked bats. In other words, there is no increase in the elasticity of the bat-ball collision.
Second, they investigated the trade off between higher bat speed and lower collision efficiency and found no benefit to a corked bat.
“We conclude that there is no advantage to corking a bat if the goal is for the batted ball speed to be as large as possible, as is the case for a home run hitter,”
However, there is a caveat. Being able to swing the bat faster allows the hitter to delay the swing for a crucial extra fraction of a second. And this may allow more accurate hits.
@@ItIsYouAreNotYour you’re wrong. Corking bats if you watched the entire video are illegal in the MLB for a reason. Exit velocity is much more. Velocity off the bat is much more. It’s not comparable.
@@kingsolo6241 Also: "It causes the bat to be 'lighter', which in turn allows the batter to swing it more quickly. However, the reduction in weight negatively affects the velocity of the ball as it leaves the bat, effectively cancelling out the advantage gained from a quicker bat speed."
It's a placebo effect. If there is a way to randomize the bat he uses I don't think he feels such a 'huge difference' The only thing his testing proved was the swing velocity.
I had no idea it was about reducing and transferring the weight! I thought it was all about making the bat more reactive from the hollow section plus cork. Learn something every day!
That’s what I always thought too. Thought the cork was to make it more “bouncy”
the cork makes it lighter while retaining most of the bounciness a solid wood core would have
same
Exit velo is created by how fast you can swing the bat. Exit velo is relative to how fast your swinging your bat. If you hit an exit velo of 90, your swinging your bat at 90 MpH.
A lighter bat makes for a faster swing. It’s why I prefer to swing a lighter bat.
its basically to take weight off the END of the bat specifically so you can whip it through the zone faster
I do corking methods for the fungo bats i make. Sometimes i do slits, and sometimes it's round bores with lightweight inserts like yours. The demarini wood composites use carbon fiber instead of cork and it actually increases durability
There's 2 ways that wood bats increase ball speed. Hardness and mass. Hardness increases the efficiency of a ball's rebound whereas mass transfers more energy total if the speed decrease is less than the mass increase. A corked bat balances out a bat design, but even if you increase the density to have the same mass or increase the mass to have the same swing weight, this kills any amount of endload. Endload bats are more efficient per swing weight than balanced bats.
This is an important topic of discussion when it comes to usssa because you can get a balanced drop 5 to feel like an endloaded drop 8, but the drop 8 will be more efficient at the same swing weight (not counting wall thickness and things like that). Wood is the same way. A light endloaded bat is more efficient than a heavy balanced bat.
For jacked pro players with enough strength to swing a tree axe, corking is less effective at increasing total power because the speed they gain maybe not be as much as the mass they lose. However, bat speed and control helps you get BETTER hits, so even though you lose power overall, you're more consistent with your power and have more consistent launch angles.
It's a complicated topic that comes up frequently with cupping, which can be thought of as a sort of legal method of corking a bat ever so slightly
My guy wrote a whole essay. Thanks for the info tho.👌
Fuck yea its Crixus. You gotta show off those bats dude! Or make some truly cracked bats to show off!
@@Thurokiir1 hey dude, you're right on time because I'm starting something to now actually. Got a few partners and we're gonna take my models and designs into production. I'm taking time off the university to work on it. I think it's time. Maybe i should make videos in here, although i don't know jack about content making lol
You could really tell that they were swinging the bat faster because as soon as they switched to the corked bat they were hitting more to left field. That means the bat was meeting the ball sooner than they were expecting it, so a bit in front of the plate instead of directly over the plate. After using it for a bit they began to compensate and then started getting one or two to center field.
Bro, the corking reduces the bats weight which allows you to swing it faster and impart more energy on the ball - they aren’t swinging harder, the bat is moving faster
The cut half way through the flex grunts is peak comedy
Very interesting seeing it done today. I did this test for a 6th grade science fair project in the late 90s using the base store bought LS wood model because they were so accessible and affordable then. I had unaltered, cork, super balls, and sawdust filled by a family friend who was a carpenter. My dad and I built a swing machine to guarantee the same swing path to the ball off the tee to guarantee being struck in the same spot. The altered bats were lighter, but nothing outperformed the unaltered bat. With a mechanical swing releasing the same amount of force on each swing, back in the 90s with ash, it only helped as far as reducing weight, not increasing distance.
Obviously bat tech and design has advanced a LONG way even in wood, but the density definitely mattered back then. Won the science fair too!
I think they main benefit is that the bat speed increases quite a bit with the corked bat
Yeah, if you know about relatively basic collision physics you can figure out that lowering weight for increase in velocity does nothing.
@@aukora129 Are you saying in the basic relationship of F=ma that the reduced mass and increased acceleration essentially cancel each other?
@@dytakeda No I'm saying that with conservation of momentum, the amount of weight lost by corking just doesnt mean anything. It would be far more effective to just use a lighter bat, but players dont feel as comfortable that way. In fact, many players use heavier bats than necessary, meaning they can straight up remove weight from their bat without changing it's dimensions for the same effect corking would give.
The point of hollowing it out is to reduce weight so you can swing it faster. A swing machine swinging it the same speed defeats the purpose of hollowing it out. This video shows a reduced weight of one ounce. Which is about 3% of the bay weight. The end result was 3% higher exist speed. It would be interesting to pressure test the bat to find how much you can take out of the middle before it’s to weak to handle hitting the ball. Taking the most weight off. Taking off 3 ounces could give like a 10% boost in performance. Averaging exit speeds of 110
I love the cut every time Zack screams 😂
I think what makes corking effective is PERIMETER WEIGHTING. It's a method of taking away weight, but crucially because this weight is reduced from the centre, it stabilises the barrel during contact, effectively creating a larger sweet spot. Look up Perimeter weighting. It is used a lot in golf club design.
Never gonna get used to seeing birch bats. Makes me feel old
Yo! Got an idea for you guys. Have you seen the puck knob wood bats some pro players have been using lately? I believe Dovetail bats and maybe marucci have them available for retail sale. It's supposed to improve bat speed and makes the bat an extra couple inches. Would like to see you guys try them out.
Lets see the showdown, Paul Goldschmidt puck knob vs the Jeff McNeil no knob!
I’ve seen Travis D’Arnaud use it and I’m waiting for the Bros to review one
Big fan of the dumbell knob/ hockey puck knob. It limits the way you hold the bat, but increases rotational power
Great idea
I like the idea, but i think the utilization is too individual to measure.
I think a guy will just do better with whichever one feels better on his bottom hand.
You guys should do one with corked metal bats. We had a bat in HS the end cap came off of and found it to be hollow with some light foam. So, we decided to pull the foam pack it with, if I remember right, tennis balls as tight as we could and used cement glue to place the end cap back on. I used the bat in batting practice the next day and hit 10 HRs in a row. One of teammate asked me to use in a game, so I did and hit a pitch low and away that would normally have resulted in pop out and I ended up going yard. Told the guys we can't use this anymore in games or we are going to be done. I'd be curious to see if it still works with today's bats.
this is kinda the idea behind non linear composite bats
Hey Ridgefield Spudders! I don't live too far from here! I remember when they were still building this complex, glad it looks so nice!
I really appreciate the alternation of each person hitting the bat! Subtle change but takes significant care to make that decision in editing! Great job baseball bat bros!
I feel like if you compressed the cork, you'd get a pressurized effect that can increase the pop. I would like to see more experiments around this like: seeing how wide of a bore you can get with a carbon fiber tube insert, maybe also pressurized with air, thin titanium tube insert.
Except other people with better qualifications proved corking bats doesn't do anything to help hitting distance.
@@sillygoosexv6778 this video had some very interesting statistics. While not conclusive by any means, if you apply what was shown in this video, a 3 mph increase in exit velocity would equal approximately an additional 15’ of carry distance. “Biomechanical researchers found that a ball leaving the bat at 90 MPH traveled about 300 feet, 95 MPH 326 feet, 100 MPH 350 Feet and 105 MPH 375 feet. The research concluded that for every 1 MPH added to exit velocity, the ball traveled an additional 5 feet.” That could be the difference of a loud fly-out before the track vs a HR.
I would like to see the same thing done but no corks in the bat, just leave it hollow with the plug on the end.
@@sillygoosexv6778 Decades of use in pro baseball prove otherwise.
The engineering term would be modifying the coefficient of restitution to do impedance matching so you can get maximum energy transfer between the bat and ball
I will make sure to try this in my next organized game 😊
I always love a new baseball bat bros upload also I remember that old vid. Your videos have helped me so much pick out my BBCOR bats. Boutta buy some merch too love the channel and keep it going
What got me was seeing how much more flat the trajectory on the corked is before it falls off. Like the tiger I's short 88 versus the long 88 on the tiger ii, the round is just going so so much faster, and it's so cool to see it happen with a baseball.
HELL YEAH! Rocking the GV Artwork shirt!!!
Love the shirt @ 4:17...S.O. AL CHAMP GUARDS!! (still the tribe like he said tho!) and lovin my guy again @ 5:05 ......"SHOUT OUT STEVEN!!!" Tribe takin out the Yankees tonight!!!!
You know it’s gonna be a good day when will uploads. Keep up the great content!!!
The first video that might have led me to your channel was a review of the Baum bat back in Summer 2020. Crazy how much your channel has grown since then!
“Apparently that video went viral in the carpenter community” 😂😂😂. Great video guys!
The sound coming the bat is one of my all time favorite sounds
Glad y'all redid this test! Thanks for the time y'all put into it.
Awesome video. Thanks for sharing!
Would be cool to see you team up with either SmarterEveryDay or The Slow Mo Guys to use their high speed cameras to see if you can see the bat flexing in slow motion. If you can see a difference between the corked and normal bat and to see a metal bat and any other variations you have.
I've always thought the cork was to give the bat more bounce in some way I've never really thought about it as a weight saving thing. I figured if it's packed tight with cork that the cork would help facilitate bounce or possibly the bat being hollow would help facilitate bounce and the cork might help reduce shock to the wood and keep it from breaking as easily. That's how I've always thought about it. Definitely excited to finish watching the video I paused it to write this comment.
Maybe try doing a nice cork job like this to a really heavy bat and see if there's a big difference. You'd shave more weight off with a harder wood.
Me too! I thought the cork was supposed to be like a trampoline and hit the ball further. I guess having a corked bat means having better control, and faster swing, leading to a harder hit without sacrificing surface density
Same here. Thought it was too make it bouncy. Otherwise, why put anything in the cavity? Just hollow it out and then put the plug on the end. Air is lighter than cork
@@LeglessWonder if the bats completely hollow then you lose all the power in your swing regardless of speed, because inertia and density or whatever
@@BebeSensei yea thats the point lol. That’s why just saying its to save weight alone doesn’t make sense
@@LeglessWonder he explained it, you get more power, not just from speed, but also bc the cork reinforces the surface of the bat. The surface density is comparable to pre-cork. It does both
Much love and respect guys keep up the hard work
This is awesome!! Thank you for this
I think at the start you said something about American Bat Smith having a Wood composite if so you should review it
Dope Vids guys. I'd really like to see a comparo between the BatSmith FT23 and the Victus Tatis23. Curious how the two models of the same bat would fare against each other. Would make for an awesome shootout! Just a thought. Keep em coming y'all!!!!!
Love that wood bat sound at the field!
I use American batsmith i love it 👍🏻
Awesome video! So glad I found this after the original.
I came across this channel because of that original video now I am seeing this one (granted 6 months after it came out) kinda surprising that it makes a big difference at least in this one video.
Thank you for the pic at the all American classic
I am a hockey guy but enjoy watching the different bats you show.
Immediately thought of Sosa when I saw the title haha. Great video as per usual. You guys ever thought of doing a bp sesh with subs type of thing? I played ball in Utah and now live in Oregon. Would be cool haha. Just throwing it out there. Keep up the great content!
I have corked quite a few the right way myself and I feel like it depends on the original wood because I don’t like the way my corked maples feel. The ball feels like it flies off the bat but then it doesn’t really carry, pretty similar to a BBCOR bat with an extra 20 or 30 feet maybe
It's super awesome you revisited this again. That's a sub from me.
In the 5th grade, yes 5th, I corked a bat.
Step 1, buy every superball your local pharmacy has and use your fingernails to make it into little chips.
Step2, drill the bat as seen in this video.
Step 3, fill the bat all the way with the superball grains. All the way.
Step 4, compress the grains and refill.
Step 5, using a wood plug with glue on it, place the whole contraption in a hydraulic press. Add 5 tons of pressure and leave it there until the plug is glued in.
Step 6, finish as seen in this video.
My older brothers friend used that bat in a preseason game. He was an 8th grader. He checked his swing, accidentally hit the ball, and it went all the way to the warning track. He was so scared that he flung the bat hard into the dugout while running to first. He never used it again because this was in the aluminum bat era around 1989.
love the Steven Kwan shoutout...go Tribe!
Cutting out the center of the bat will allow it to oval the barrel slightly on impact (at least compared to the control bat that is denser and more compact in its form) and then the bat will spring back to normal shape adding a bit of extra pop off the bat! Being lighter I don't believe helps with power simply because it will slightly have less follow through power and you can just purchase one that is an ounce lighter, which would end up sacrificing a bit of density to be lighter and distance never goes up with the same hitter! Also, I would imagine cork bats require a lot of impact to see the intended results. Even though the center has been replaced with a less dense material making the spring effect easier to achieve, I believe the impact between bat and ball would have to be extremely high. In conclusion, the harder the bat is swung the more advantageous it becomes IMO!
Watching another video/channel...saw a bat bros video notification and IMMEDIATELY clicked on it! #notdisappointed
I was at a White Sox game once when Albert Belle hit a HR for Cleveland and I said to the people I was with, that sounded weird! They should check his bat.
The next night, they did. BUSTED!!! 🤣
That grain orientation on the end plug is doing my head in!! Shoulda been the other way around…
Other than that…
As a ball fan AND a full time carpenter. I love this.
I swung a 33/31 in our mens league, ash bat.
It’s insane how much more control you get with a lighter swing weight and shorter bat.
😂 fair point, we just weren’t worried about disguising it
I’ve got a Rawlings Fungo that was hallowed out from the factory, it was fun to play with when I was coaching!
Thanks for giving a shout to our Cleveland Guardians! Steven Kwan!!! My man 👊🏻
Such a satisfying sound.
How about using expandable foam instead of cork? Will it work the same or better?
Well done Will!
Let's just take a moment to think about how well they throw for these vids...🤣🤣🤣
Love ur vids I just got a cat9 comp a couple months ago but my fav bat is the meta
My buddy's dad corked a bat for us when we were like 10 playing in the back field. We spent more time looking for the balls in the woods than playing.
Nice video!
What is the purpose of the cork? To hide the hollow bat? Is it the weight or some other phenomena helping?
hey man how you doing? I need your help, can you test the difference between BAUM BAT & KR3, what is the best composite bat? I would like to buy one of them. thank you so much, you are the best!!!
Use this comment as a call button for "Smarter Every Day"
Love ur videos
Bro, that OG Rays hat is 🔥🔥🔥
Love the tribe and now we’re in the ALDS let’s keep it rolling
That corked bat sounds SICK! 🤣👌
hi guys, great vids. thank you for them as i've learned so much. I live in the Tampa area. Where is that facility you're in? I couldn't make out what you said.
Hahaha I didn't expect to see my comment from the last video in this video! Awesome job revisting this!
You might not have many mechanical or carpentry skills but we're here to see you hit dingers and you do that well. Keep them coming.
I've watched both vids and some of the comments on that first one really were unnecessarily shitty. Have always been curious about this subject, so appreciate the effort to demonstrate how much of an advantage a corked bat actually is.
Do you suppose using an expanding foam like "Great Stuff" would lighten the bat more, and keep the bat strong enough?
Aye dude rocking the Oreo 5s 🤙🏿
Great video!
"bout 3 inches in"... Sounds like a friday night at my place 😂😂😂😂.. I could'nt resist.. I tried
True temper dynamic bbcor bat review
THIS IS MY HIGHSCHOOL FIELD AHHHH
👍From this day forward you will be known as "Will the Legend". May your tankard always be full and the tail never end. You lucky sob you 😉Rock on man🤘😎
Yeah I knew y’all was hitting cars lmao 😂 back there
Bro that first swing that zack took with the corked bat sounded just like a perfect perfect
I am not a baseball fan and have never in my Life heard of corking, but this video makes me wanna play baseball this is just fun as fuck I wanna hit a baseball right now
i love that sound..
Yooo is that GV ARTWORK shirt ! LETS GOOO
The ALBIN aluminum alloy AX05 BESR bat was ridiculous in 2011, under the radar bat but it smacks
Awesome as always, but, ready to see if the '23 Omaha might be worth making a change for!
Love the vids
Have you tested two identical bats with one ounce removed from one of them via cupping? Seems like it be be the same only it could be legal.
That was probably the biggest news in the “carpentry community” over the past century 🤣
I’ve got a 2009 Easton stealth cnt sc900 y’all can test again some newer and older bats
That is crazy!
Legit legitimately legit legit legitimately. I'm so drunk... I made it a drinking game.
Great video
Bro wills hands are so good on his swing… gets the barrel where it needs to be…. Love his swing
Definitely a difference cool stuff
Damn, you start hitting at ridgefield right after I move north? Wild 😪
Never understood the big brains behind putting a field right next to an active road...Like it seems like whenever you see a baseball field or golf course they always decide...Yeah lets get these flying projectiles and just aim em right at people in cars XD great video and its in no way ragging on you guys, I've just seen so many fields with this blatant 2 seconds of thinking flaw and find it funny.
what if you drilled it the same but filled it with a foam which you let expand, then cap it normally like here? maybe even lighter and possibly still structurally sound?
5:23 the cutoff 😂
Hopefully you can bring the corked bat with you next time you collaborate with Eric sims. Also would a corked bat show up in a x ray?
Haha that’s a great question. I would assume so!
You can swing a lighter weight bat faster too.
Also I think there should be a league that allows all of the illegal stuff. Corked bats, pine tar, anything goes. That would be fun to watch 😂
would be more dangerous
Can you guys review the gley25 from marrucci? I have a 32 and love it. It has a crazy sound too it as well. Love what u guys are doing
I'm not really a baseball guy, but I was curious why you would put cork in your bat. Well, my theory about that got confirmed.
And seeing the direction of that field facing, I assume Baseball isn't about guys running from base to base while another guy tries to catch the ball, it is a game where you try to hit pedestrians and passing cars. Corking your bats seemingly really improves your chance in doing so. I can even hear them screaming: 'Stop!Stop!'
;-)
Wait American Batsmith makes wood composites might have to get me one
