In a year or two, we are going to get a video titled "GIANT Tungsten Rod DROP From SPACE! World Record Explosion?"

12:40 The reason you're losing bounce height is likely because the ball is approaching terminal velocity (where air resistance cancels acceleration).
Once this happens, the ball won't bounce any higher no matter how high you drop it from.
Yea I think so
Well you can tell it hasn't quite reached terminal velocity if the crater keeps getting bigger, which probably has more of an effect on the height of the bounce.
@@nodangles6983 Gryph0n is right. It's not the size of the crater that matters. At terminal velocity the hardness of the ground is the only variable in how high will the ball bounce. They could drop it on reinforced concrete and get 60 meters without a crater at all.
@@caliconfessions1075 The larger crater indicates a higher speed, which means it's coming in at a higher velocity the higher it's dropped, which means terminal velocity had not been reached. The larger the crater, the more energy its construction has taken away from the ball.
@@nodangles6983 the softer the impact site the larger the crater will be and the lower the bounce will be. Balls typically reach terminal velocity around 10 seconds or after falling about 750 feet.
1000 vs 2000 foot drops are going the same speed upon impact the size of the crater is based on the hardness of the ground, not the speed of the object because the speed from 1000 feet and 2000 feet is the same speed. It's called terminal velocity.
Just goes to show how severe a meteor impact is. That was only about 120mph on impact for a 1 tonne object and it was impressive. Imagine what being hit by something the size of a mountain would be like.
I just came to comment similar and then saw this mate. A meteor impact must be severely extreme
*Wombat screams*
Scott holding up Bretts arm while waiting for the drop was a hoot. Science with Gaunson is always welcomed. 😊

@@b2dmore3078 yeah, aliens will be confused👽
@@docy5974 who were these mysterious figures behind all this😭😀😀😂
@@b2dmore3078 😂😂
Was just thinking something similar lol, gunna have someone confused at least XD
The biggest issue in getting a higher bounce from a larger height is terminal velocity from air resistance. The closer an object gets to terminal velocity the less it will accelerate, so even if the distance to the ground is twice as large the velocity is likely significantly less than twice as large due to decreasing acceleration and plateauing velocity which is what happens when an object approaches terminal velocity.
I'd think that the efficiency of the bounce is the biggest thing. A back of the envelope calculation for the terminal velocity of a 1 ton sphere says terminal velocity is about 72 m/s, and in a vacuum the sphere dropped from 2000 feet would only reach about 108m/s. So drag does play a role, but it can't account for the sphere bouncing only 150/2000 = 7.5% of its drop height. The ball is losing most of its energy to heat as it deforms into a pancake and displaces the dirt. If they dropped a diamond ball on a diamond field (and it weighed the same somehow) I'd expect it to go much much higher, as long as it didn't shatter, despite feeling the same amount of air resistance and having the same terminal velocity
The diamond ball would shatter no matter what from that high up
@@broski761 indeed diamonds are hard but surprisingly brittle. They may be one of the hardest minerals but their molecular structure makes them not take stress well. This is why despite their hardness they are relatively (to their hardness) easy to cut.
Dimond is not unbreakable.
Its actually the amount of energy lost at impact, rendered in heat form or force direction. So terminal velocity is used but not really mentioned because its obvious that terminal velocity must be reached, so why bother mention it...
Easiest way to check this is to check the time from release to hitting the ground. Compare the time of the drop to what you'd expect in a vacuum. If there is a significant difference, air resistance is coming into play. And if the time is close to double from 1000 ft to 2000 ft, it's getting to terminal velocity pretty quickly, and going higher isn't going to change anything.
I recorded the sound of the drop at 14:45 and slowed it down by 50%. It sounds like a missile!
Great stuff, guys. Greetings from America! 🫡
that is what it sounds like when big things meeting air resistance lol. i much prefer it to a missile though.
Why didn't they drop it on concrete: Typical Aussies!
it sounded horrible but awesome _xD
gave me wash flashbacks i didn't know i had
I’ll save you time. It bounces straight back into the helicopter, killing everyone on board.
I think the bounce factor would have been far better and more consistent if you dropped the ball on a hard surface instead of grasses filed, which likely absorbed a fair amount of the force - particularly increasing as the high increased.
I was just gonna say this but you nailed it. Good freaking job Rob.
True, but you would need to be pretty sure of your hard surface, that kinda impact could easily break up a concrete road or parking lot
That's true, but there also needs to be some sort of hard coating applied to the ball to hold the bands together, making it into kinda a giant golf ball. If you've seen golf balls bounce, imagine one six feet in diameter... :D
@@shadylampable I don't think them guys are worried about breaking the ground up. They love checking the impact crater. LOL. But if they did do it on hard surface rather than grass...I am certain they would avoid doing it in a shopping center parking lot or some ones driveway. I work with concrete everyday making railroad ties. That ball ain't even gonna chip the concrete we make. We pressure test our concrete for Amtrak. It takes a considerable amount of force to cause even a hairline fracture. I don't think a road would stand up though at all unless it was the autobahn highway in Germany or something. European highways carry more traffic and considerably heavier truck weights than U.S. roads so it was built to handle that.
@@Crusader1815 That would be awesome if they made a giant golf ball. No giant foot balls though. Those things bounce so unpredictably. That would be scary
As one who works with helicopters like that (obviously maybe not this type of cargo) my guess is that the budget for this video must have been one of the highest you’ve had. Tremendous work lads, keep it up. Loved the close up shots on the equipment as well.
Seriously. Surprised they didn't get a sponsor
how much is a chopper for a day
@@MelbourneAlan it’s per hour
@@MelbourneAlan the cost to operate an AS350 for an hour is about 1600€. Say it's maybe 3 or 4 flight hours on that day. That's like 6400€. Only a rough estimate
That said, there are other helicopters out there, but to lift that much it's probably the best one for the job at that price.
Thanks to HR for all the fun they provided over the years.
I feel this just means we need Part 2, but on harder ground.
Yes, I think it will bounce higher if it falls on concrete
Yup, a rebuild with a nice tight stretchy cover on a structural concrete slab. Of course it's the scale issues that will be most interesting...
Yeah, I think that's our problem. The Ball has X amount of kinetic energy, but part of X is being diffused to shove the ground out of the way. An object in motion wants to stay that way and all that, but it also wants to keep moving in that same direction, so shoving the ground out of the way is the simplest solution, at least to the eye of natural physics. If that isn't an option, the kinetic force has no choice but to rebound, so...higher bounce :)
But where could we find hard enough ground that isn't around people, and nobody would mind if we destroyed it a little? Hm.... is there a military base that we could borrow where drag racing tanks is a common practice?
@@ZeraSeraphim good point...hmm...maybe an abandoned air strip perhaps? Something like Wisley Airfield
And drop from 6,000 feet. Or whatever the aircraft maximum altitude is
This is childlike wonder in video form. You guys are doing the kind of things that I would've daydreamed about when I was about 10 years old, and as a 38 year old, I couldn't be happier to see those daydreams come to life (especially because, at that age, I hadn't yet developed a fear of heights!) If you aren't living your best life, no one is.
That was beautiful
Congrats on the heart from them. :]
They're literally me and my brothers throwing things off of rooftopes, mountains and whatnot (ourselves included...)
Didn't someone notice that how strong is that helicopter 💀
Took the comment right out of my mind bro!
You sirs, are answering the important questions!
I have thoroughly enjoyed this chaps. Laughed a lot . Great fun . Thanks to everyone.
Love to see this done on concrete, maybe an abandoned runway or something?
Stick a layer of truck-bed coating on what's left & go again (Bands need more talc for lube & a bigger 'Pof!' : )
I just had this thought before I saw this comment, concrete should make it bounce higher
YES!!!

I'm convinced Michael and Editor Jack are the backbone of this channel ❤
Being an engineering student and watching Gaunson trying to explain energy displacement pains me greatly.
This is some wild content, guys. Keep doing this!!!
Hahahahaha, energy displacement. Do you mean the Wave of Force Transfer, by accident? Internationally and among real engineering students also known as WOFT?

Never ceases to amaze me that a group of men have made a successful RUclips channel and career from simply dropping all sorts of random objects from different heights and just having fun every day. Truly living the dream!
It makes me lose hope in humanity.
I was hoping they would just go straight to a mile high and let it rip right off the bat.
Loudly
@@trorisk why?
@@trorisk hmm..... weird.... considering tik tok exists.... this doesn't even come remotely close.
Love the incoming sound of "Lofty" !
You guys really banded together on this one.
The drop pilot deserves some recognition for his work. I’m sure dropping that much weight at once had to play hob with controlling the helicopter.
It would but study the way the fire helicopter pilots add in power, collective and pedal whilst filling up water tanks and staying in their spot. There would be a lot more craft in that.
no bc the ball will be directly under the centre of mass so it wont sway the helicpoter
@@somalianjim6050 well that but do you not see how much the ball was swaying? So dropping it off to the side could mess with stuff and if you shoot off and start to panic you could go down
just like a crane... when holding a weight u will have a counter reaction when the load is released quickly. small or large, it will happen. the reaction of the operator/pilot will depend on experience

DID YOU CLEAN THAT MESS UP? beautiful landscape!
You should do the same experiment on a concrete or solid surface, higher bounce for sure.
The wobble is the force of inertia building up and forcing the massive uneven weight to consolidate up to it's new center of gravity. ✌️😊
The fact you guys take it off, explain the concept AND drop the ball within the first minute earns my respect, like, and sub 👏👏👏
yes. god bless these crazy buggers!
They've absolutely nailed the technique of showing something big in the beginning and then building up to it or building on it for the rest of the video.
Never a dull moment with these guys.
They did it at 2:28 like that’s not a good amount of time to me
Right, it's definitely better than 20 minutes of blabbering build up for 1 minute of the action.
A bit of Science with Gaunson, a bit of Rexy, a bit of merch, lots of big bounces, a naming of an item, helicopters, slow mo, tower mention and a we'll pin ya. Can't really ask for more from a HR video. Great work.
"Science with Gaunson" that's like a contradiction, Gaunson is scientific like a flat earth video. lol.

The helicopter shots really emphasize how high that ball is way better than the ground shots.

Umm, no, the helicopter shots exaggerate how high the ball is because camera lenses don't work like human eyes.
Ahh yes less drop it on a road near house and people
It really needed to be dropped on a far harder surface - ideally solid rock or reinforced concrete. The amount of KE that is absorbed by turfed/grassed soil is amazing. I did a very similar (although much smaller in scale!) project in high-school. Depending on the water-content and density of the soil it would adsorb up to 70% of the kinetic-energy, at impact, of a mass at terminal velocity. We used iron balls (3kg shot-put), 3kg solid-rubber, water-filled polymer and a few others.
Yes agree and might even crack the concrete.. 👍
The higher you go, the more the ground absorbs the energy, resulting in less bounce so simple!!
Just found this channel, I love it.
Oh wow. You guys, after a quick Google, have made the biggest bounce! The record WAS about 95 feet, or just less than 30 meters. Congrats!
It would be interesting to see how the ball bounces from 2000ft onto concrete. Less energy would be absorbed by the ground for sure. Also i wonder if its possible to land it on the giant axe from that hight.
It would just shatter in to a million bits. My guess would be 0 bounce, but the explosion would be pretty cool regardless
Referring to the Statue of Liberty as "Torch Dude in New York" is the best thing that's happened to me, today. Good on ya'.
This is pretty awesome, salute to the team that put the rubber band ball together and you too for bringing this to us

WELL DONE I ENJOYED THIS THANKS GUYS
i love how the appeal of this video isn't big explosions of things flying everywhere or colliding.
it's just simple physics of seeing how high you can get such a massive object to bounce off solid ground.
real refreshing honestly
Gaunson's calculations are a LITTLE off. When it comes to physics you want to use the metric system for all calculations. Not feet. It's simple science and math.
I also loved the sound it made. Like a meteor sailing towards the ground.
Ian Lee- the difference between the rubber band ball and a meteor is that rubber band balls are actually real.
Would've been cool to try in on a harder surface as well.
Yup. The sod ground is absorbing a LOT of the kinetic energy ... a concrete airport runway would be dramatic!
Yep. Find a big, abandoned parking lot somewhere and try again. I bet you get at least 50% higher bounce.
It broke apart even on the soft ground. On a concrete or paved surface, the entire ball would have simply shattered to pieces and not bounced at all.
@@rickmorse9884 especially with planes landing and taking off....
@@cryo9216 It would have bounced higher from shorter drops. Yeah of course it would have broken apart sooner...but you'd still be seeing higher bounces earlier so it would equal out. Plus you'd see some pretty incredible pancaking footage.
Excellent content and presentation. Glad i found this channel. 😊
I love that you guys have given it to us in feet, too. Thanks.

@@BreadApologist right. 👌
I may be a year late but man oh man is that backdrop so amazing that perfect sky and that lushes green grass. I could stay out in that field all day everyday.
A fair amount of loss in bounce height can be attributed to losses by way of heat. The faster the bands expand, the more heat gets generated. This temporarily reduces the bands' elasticity, there by delaying the return to resting state while the ball is still in contact with the ground.
No way you guys cleaned up your mess entirely!!!
2O seconds in and you’re already showing footage of the helicopter picking the ball into the air. No BS filler, love it!

Great video. And these guys really enjoy doing what they're doing
Great video. You should recreate this but higher!
I want it to be 440kg but I don't think there's enough left. Those explosions were something else though, the bands flying everywhere was just incredible. Great job catching as much of it as you did¬
The loss of bounce was due to the energy transfer in creating the crater and the full compression of the ball caused a lot of the energy to travel horizontally instead of vertically. The loss of bands had a minor effect with their energy not returning in the form of bounce. Dropping on a more solid surface like concrete would have saved much of the energy. I bet the temperature inside the ball went up substantially too.
Yeah imagine bouncing this from concrete, it would hit the helicopter back :D JK
Losing mass and rubber bands on the bounce disperses energy so the ball won't bounce higher. However the fun and excitement hasn't peaked out!
Those craters were pretty impressive for a fairly soft ball, I'd love to see what an atlas stone or Bruce could do from that height
Makes me understand the whole concept of meteors being scary if a rubber ball falling from that high craters that big

That was fun. I hope you picked up all the debris from the field.
Im sure they got the big stuff, but i'm curious about the Smaller pieces, the little 1x1 square pieces he picked up..
It's like the separation with the ball and then it bounces like the Spirit Rover.
Now I wanna see this with a huge steel ball. Not for the bounce, but for the crater
Awesome vid, more dense landing surface might make bounce results more impressive.
This was super incredible! The craters that ball left in the ground were just, amazing! Let's go 44 club!
From a Google search
1,500 ft
When falling in the standard belly-to-Earth position, an average estimate of terminal velocity for skydivers is 120 mph (200 km/h), and a falling person will reach terminal velocity after about 12 seconds, falling some 450 m (1,500 ft) in that time.
Casually captures a UFO in the back of their video, watch from 9:12-9:20 as slow as possible and look in the sky, you'll see a black craft flying at breakneck speeds that is still easy to miss at the slowest speed available.
I cannot express how happy I am to see the data being collected 😅 (Next time -- please keep collecting data! -- count the crater height as part of the bouce)
As a data analyst I loved the graphing.
I'd love to see a video of the clean-up!
Deformation costs a crapload of energy so it was to be expected that it would drop as soon as it started shedding. That's partially the reason it doesn't scale linearly already on regular bounces but those rubber bands flying off of it had a lot of energy in them that wasn't directed upwards anymore. Another reason could be terminal velocity approaching at some point making sure going higher no longer makes the ball hit harder because all off that juicy energy goes into air displacement.
