The drop tower: The ride where you get exited for in line, freak out once you get to the top, and then want to go on again when the ride is over.

[@megomi652]

Felt that

[@thesily]

exactly

[@moritzvh1702]

So true

[@Maltanx]

Unpopular opinion: towers that shoots you up at high speed are much better than simple drop towers, expecially if the fast climb is immediately followed by a free fall. That way you basically experience two rides in one with also the brief but intense moment of absence of weight when you reach the top. BTW, amazing video as always! With your consistent and great production quality there shouldn't even be the need to say it anymore

[@flipclone]

hell yeah, i love the pneumatic ride better, shoot up, experience weightlessness for a second or two, then drop!

[@user-K8T]

I'm a big fan of the fear and intimidation factor. I want to reconsider all the choices in my life that lead me to getting on that godforsaken ride before it drops me.

[@hoshimaruhajime7933]

[@tsunghan_yu]

[@sleet1650]

余宗翰 yeah this seems like a really popular opinion. “I like my rides to be more thrilling!”

[@tristramcoffin926]

I love roller coasters but I find drop towers much more frightening.

[@Br1ttany1992]

Me too! I can't ride drop towers but I could ride roller coasters for days.

[@randomvideosn0where]

I don't find either frightening, the only ride that really got me was the water slide with free fall at the top. When the floor dropped out there was definitely a moment.

[@abbymango3452]

I rode one too many drop towers and now I’m afraid of elevators

[@pypeapple]

Right? any coaster any day, but a 100 ft tower is a hard pass

[@irrelevance3859]

Same. This is why I have never been on one lmao. They're frightening. I'll stick to roller coasters

[@ragnarok9899]

Is the pneumatic tower really a better and safer design? I'm not not an expert by any means, but a ride that relies on pistons and cables literally running through compressed air containers, and you just have to hope the seal holds, just *feels* worse than a magnet which has no moving parts and just works, even if you need the extra hydraulics at the end to soften the fall.

[@JannikVogel]

I'd also be interested in more details about this. And maybe analogous situations to explain the forces / pressure that is involved. How strong are those cylinders? What do those seals look like? ... I'm impressed you can have such a long pressurized cylinder in this mode of operation (repeated changes of pressure, outdoors, very long, cables/seals which probably have a lot of friction, ..).

[@keco185]

It doesn’t seem safer. On a side note I remember an instance of a cable snapping on one of these and getting caught on a rider and severing their feet. I’m guessing this setup requires extra maintenance to make sure the cable traveling through the seal doesn’t wear and if that maintenance isn’t performed, the ride becomes less safe.

[@annelorraine9529]

keco185 What you’re talking about actually happened on one of the magnetic breaking Intamin models, Superman Tower of Power at Kentucky Kingdom. The lift cable was worn down and not properly maintained and snapped mid-lift, wrapping itself around her foot. The ride operator failed to notice this and stop the ride, allowing the “drop” to take place. The force of the free fall pulling on the snapped cable wrapped around her leg was what severed it, not the cable breaking itself

[@ma9c]

@@keco185 actually that accident happened on an electromagnetic brake tower from Intamin in Kentucky kingdom. The cables were from the catch car that lifts the vehicle, not from the dropping mechanism. It wasn't properly maintained.

[@VIctorAbicalil]

It probably has other safety features for the case of emergencies, just like regular elevators.

[@ecoomber]

I was really excited when I saw the aerial views of Canada's Wonderland at the start!

[@DRockeh]

Same here. I once worked at Canada’s wonderland. Drop Zone was my first year ride group:)

[@midievalcat7770]

I remember seeing a drop tower in Celebration Center, Utah that instead of using brakes, had a tube that when the cabin dropped through, the air in it would be compressed, slowing it down

[@Lettuce2.]

Oh yeah that's a sonic boom made by S&S

[@indigotter]

Yup! One of the most unique drop towers ever made. Sadly it doesn't operate anymore.

So it didn't use the "breaks"? Did the drop tower get paid for not using the "breaks"? Aren't "breaks" mandatory? Were the "breaks" considered overtime? Did it hopefully have mechanical "brakes" like the ones described here? Sheesh.

[@Hunt3rr4455]

200iq

[@ryan_n05]

@ No, no, yes, no, no. The was basically like a cannon with a drop tower gondola going into it. The ride vehicle fit perfectly into the "cannon", so the compression of the air would make braking force.

[@sarahnade8663]

This actually makes drop rides far less scary when I know its practically impossible for them to not slow down at the bottom.

[@Kudown]

Yup science👌

[@cssSUL]

except the kid that died the other year died because the harness malfunctioned

[@mandi8345]

@@cssSUL And THAT is what keeps me off of rides that go upside down or too high.... Im mechanically inclined, I didnt build it, Im not maintaining it, I have no idea who is.....No thank you. Still love puke rides (carnival rides, like scrambler, octopus, the UFO, zipper, etc), and wooden coasters. but yeah...all it takes is for someone to get in the habit of not checking a pin, or they do check the pin but that pin has a flaw in the metal....NOPEITY NOPE NOPE!!!

[@mandi8345]

I was the same way with airliners and their wings....until I saw a video of how they test them. They literally strap the plane down, put a winch on the wing tip, and bend it till it breaks. Go check one of those videos out, I guarantee the wing tip goes far higher than you thought it would...

[@fatha2092]

So, can this magnetic braking system can be used for an elevator emergency brake?

[@erwanrc8117]

Great question !

[@Maltanx]

Yes, they are already used in some elevators. The final brake is done by basically putting a giant spring or a piston at the end of the shaft

[@Stubwood_on_YT]

Tom Scott made a video which uses magnets, kzbin.info/www/bejne/oZW3pJV8iJmro6s

[@DomDoesCoasters]

Not really... This braking system is quite expensive, worth the investment if its intentionally being used every 30 seconds over and over again, but in an elevator where it will never be used unless there is a catastrophic failure its just not worth it, also elevators are already really safe as they are Another issue is that these brakes are so safe BECAUSE they are permanent, they can't ever be switched off, this is great for safety, but remember we do have to lift the dropcar up there in the first place, this means you will always have a braking force applied to the dropcar as it is pulled up, but remember, the faster the dropcar the greater the breaking force. basically the drop car starts off being lifted very slowly to minimise the braking force but speeds up once it clears the brakes if you built an elevator with this system it would be REALLY slow and inefficient and a lot more expensive without any actual benefit because they're already really safe and accidents are extremely rare.

[@FireCat_P]

Elevators already have more usefully braking safety systems

@@chaumas I don't personally consider waterparks to be amusement parks. Amusement parks focus on mechanical dry rides, and while Action Park did have an S&S drop tower, it resembled a family entertainment center and water park way more than it did an amusement park.

[@Jonas95]

The best pneumatic free-fall I have ever done is probably Mystery castle at Phantasialand. There is a very impressive thematisation and a whole story told with 3 different fall-patterns that are randomly displayed during the day and it is completely in the dark. Very thrilling experience if you like free-fall rides

[@mirvha714]

Hands down my fav was the original Universal Studios Tower of Terror (when it was first released). It went up and down rougly 10 times and had 12 different patterns. You are fully enclosed only to see how high you really are when the elevator door opens to reveal the outside world. They changed how it operates now, so it's no longer as varbible.

[@Br1ttany1992]

Drop rides are the only rides that legit scare me 😂

[@Sp00kq]

Yea same. I can handle 103 foot drops on roller coasters with no issue, but drop towers are the rides that scare me a little bit

[@kasity]

I live in Gothenburg in Sweden where we have a 90 meter intamin droptower and I just love regretting my life choices when taking the long journey up and then screaming at the top of my lungs when it falls. The ride is called AtmosFear if you want to see a POV :)

[@aanshuk]

These are so interesting because these videos explain how things work. Things that most people don't usually think about. And in a way that's easy to understand. I love the videos!

[@AverytheCubanAmerican]

The Parachute Jump! Nicknamed the Eiffel Tower of Brooklyn. That was the tallest structure at the 1939 World’s Fair. Moved to Coney Island in 1941. It was abandoned for a while after it closed, several people even tried climbing it. Luckily there’s been a restoration and it was renovated with LED lights

[@ThunderDashHub]

Love drop towers. They are intense but loads of fun. PS. With my perfect pitch, I've determined that the highest pitch produced by the magnetic fields and eddy currents when the gondola travels through the magnetic brakes is a G#3 on early intamin drop towers (the 4-gondola version). This pitch correlates with the speed of the car. It sounds like a synthesized descending glissando.

[@dewitter323]

Canada's Wonderland in the beginning made me so happy! It;s cool to see a ride that you've been on before :)

[@WANDER1NG-MIND]

Drop towers are my favorite rides. I've always had my guesses about how they work but this video was extremely informative !

[@CraftingCake]

Does the air get also shoved down back into your lungs when you were trying to scream or breath when falling? I found this to be so uncomfortable, I do not want to ride a free fall Tower again. Do you have a technique to deal with that?

[@AmusementLabs]

I have some footage showing close ups of all the equipment on the double shot (SCBB). also I think the shot thanks you referred to are not exactly called shot tanks. Aren't the shot tanks the smaller side tanks used? Also, what about the relief valves, gates, etc? Those might have been fun to learn about too.

[@viddork]

One of the first times I ever did a ride of this type was the Big Shot (who knows what it's called today) on top the the Stratosphere in Las Vegas. The one where the base of the tower is some 1000' above the ground! Midway through the ride, I looked down at the observation deck below me and all I could see were faces staring up, wondering what all the noise was about. It was me. But the best one I've done is in Silverwood in Idaho. Not the tallest by any means, but I've never been on another one that lets you drop as close to the ground before putting on the brakes.

[@Benderboy121898]

When I was a kid I would go to my country's only proper Amusement/Theme Park, Oakwood. There's a ride there called 'Bounce'. It's a drop tower ride that uses pneumatics. But as you can probably deduce from it's name, it had a car that went all around the main tower, however was square-shaped. The ride would start by shooting you high into the sky, and I always remember the violent hissing and screeching of the ride that just added to the terror and anticipation. Then it would fall after reaching two thirds up, then come down and bounce a few times. Then it would fully lift you up slowly, and hold you for a few seconds and the ride operators would always fake a countdown and drop you without knowing. You would then plummet and bounce up and down a few times before coming to a gentle landing. That ride was probably the most (or joint-second) fun ride in the entire park! But as you can imagine, with H&S getting stricter and stricter as the years went on, it ended up transitioning to just a regular old drop tower, as it did tend to jar you and hurt your back a little. That park is dead now. They try to revitalise it and keep it going, but it's so run down and boring, it's just not worth the insanely expensive £30 entry. Plus there's like literally only one place to get a takeaway burger from and it's super expensive.

[@toxdazcubing]

the canadas wonderland drop tower u showed at the beginning is the only drop tower ive been on.

[@tilgare]

I would have liked to know what sort of drop tower construction each of the more commonly known drop towers is - the only one I think I've got figured out is Dr. Doom - you can hear the compression and air exhaust, it must be pneumatic.

[@lovetodocoolstuff9309]

Ya here in Alaska we have one carnival company called Golden wheel amusements that does all of the fairs. I did my first drop ride with my five-year-old daughter. They wanted to put us in seats that were not next to each other because one of the freaking seatbelts was broken. Let me assure you safety is not a concern for every company

[@pjfleury4]

I want to know more about the cable seals on the pneumatic tower. How can a moving cable pass through this air tight tank at suck high pressures without air leaks?

[@shawnspencer8766]

There is actually always air leaking through the cable seals. It used high density rubber tight on the cable and grease to help it pass through the seal. Since there is always a small amount of air leaking, the gondola will always slowly return to the ground in the event of a power failure, making it virtually impossible to get stuck on one of these rides

[@DennisGr]

[@spencersloan4872]

The first drop tower that was shown at the start of the video at Canada’s wonderland, I got stuck on that exact one!😂😂😂

[@triple7marc]

I got stuck on the one at California’s Great America. It was probably just a fault in one of the sensors that caused the carriage to stop on its way up. Nothing to worry about. Remember, even if it started dropping halfway up the tower, it would still brake and come to a safe stop at the bottom.

[@195511SM]

Back in the 1990s, I happened to be at Marriot's Great America in Santa Clara, CA....when there was a widespread power outage from Canada to Mexico. I wasn't on any rides at the time, but spent a couple of hours walking around, waiting for the park to come back online. I remember seeing riders still locked into their seats.....but it was at the very bottom of the tower. They just couldn't get the harnesses to raise, so that people could get out of the seats.

[@triple7marc]

That means that the restraints are locked in the event of a power failure, which is a safety feature. If the carriage was on the top of the tower, you wouldn’t want the restraints to open if the power goes out.

[@ChrisJones-gx7fc]

For me it's not so much the drop I'm scared of (I've ridden Tower of Terror and loved it!), it's being that high up in the air. In a dark ride you don't know how high up you are, and only feel the sensation of falling without seeing it.

Of course I've been on the world's tallest Intamin giant drop ZUMANJARO drop of doom in New Jersey. The other tower, Superman Tower of power in Kentucky had a mishap in June 21 2007 when the last trip upwards, one of the cables snapped, due to failed inspection, that caused a guest to be maimed, losing both feet during the free fall. The guest's right foot reattached but the left was amputated. Kentucky Department of agriculture investigated the incident.

[@leeowen4989]

As an engineer I think this video is excellent as always. However your description of S&S towers isn't quite correct. The large cylinder in the middle is the main air receiver and this can take up to 10 minutes to pressurise to 120psi depending on the size of the compressor. This tank is divided into 3 seperate sections which are isolated from each other. The middle section is supplied by the compressor and is maintained between 100 and 120psi. The upper section is the shot tank, this is filled by the middle section after the car is weighed and is then re-isolated from the system. When the ride is in the launch position and the shot tank is at the calculated pressure which is usually between 70 and 85psi, the shot tank is opened up to the 4 cylinders using an enormous electro-pneumatic gate valve. After completing the space shot, the car is raised to the top of the tower and held by the brakes. The bottom section of the centre tank, called the turbo tank, is filled to about 30psi. There is no gate valve at the bottom however, so the pressure in the turbo tank is applied to the bottom of the pistons at the same time as the tank is filled. The brakes release allowing the pistons to shove the car back down. An interesting safety feature of the S&S towers is that the restraints can't be opened if there is more than about 12psi still in the shot tank when the car is back on the ground. So if you have just had a ride on one and there is a delay of more than a minute or so in letting you off, this is likely the reason why.

[@shawnspencer8766]

That's cool. The one at the park I work at operates a little differently, sounds like it's probably an older model. I'm sure the letdown valves are still the 4-20ma positioning valves though on the tower you work on?
