Quite the "memorable" experience for all of us back in the day

[@SpartanGSD]

The entire episode I kept thinking...if a sticker could throw off a helicopter...what happens when a bird dookies on it? (Parked outside not while spinning) ... This myth was busted before it even began

[@aegrotattoo9018]

Or the poly tape that is used on certain leading edge abrasions 😃

[@Omniprong]

Absolutely. Take a light aircraft out for a flight in the summer and see how many bugs are left behind on the windshield once you're finished. You'd better believe at least a postage stamp's worth of extra mass will be left behind on the rotor blades over the course of any given helicopter flight. I'm also pretty sure I once saw a picture of a Soviet Mi-8 with bullet holes in the rotor blades that had been covered up with duct tape. I appreciate that they give every myth a certain degree of prima facie respect and due diligence, but I'm surprised this one made the cut at all.

[@CZProtton]

@@Omniprong Mi-8 is a combat helicopter gunship, even though its mostly for transport, that thing can take a lot and still fly. Not indicative of how a more civil helicopter will work, I assure you that a regular helicopter will most likely lose a blade if you shoot it.

[@Omniprong]

@@CZProtton A military helicopter is definitely more robust than a civilian one, but the difference isn't so substantial that one could fly with bullet holes in the rotor blades while the other would be rendered unflyable by a postage stamp. My point was that helicopters just aren't that sensitive, and there was enough readily-available evidence out there even at the time the episode was filmed that I'm surprised they bothered testing it.

[@NoriMori1992]

Yeah, I genuinely don't understand why they did this one 😆 I guess just because RC helicopters are fun.

[@Wampa842]

I wonder if this was the episode where they discovered the super secret non-nitrogen-based homemade explosive. Speaking of *bomb,* 2:23. Formative moment for so many of us.

[@MrValis169]

Swell proportions indeed.

[@markedis5902]

It was the pierced tongue that made it for me. It’s known as a ‘functional piercing’. If you need help working out the function then you’re missing the point

[@ytiralc]

This is definitely the episode where they went full on hunting for viral stuff. I keep wondering what the show would have been like with less internet.

Surprisingly, Kari Grant and Tori actually redid the dry ice in bottle test and prove the myth that that explosion can blast off your thumb if your holding it.

[@rob3125]

26:31 Now i understand why Jamie don't like working with Adam. Adam spills a bottle of cola in a $30000 lathe. In the episode about Quick sand, Jamie warns Christine about makeing mistakes on the $30000 lathe and tell her think before act.

[@mirabilis]

A 1:7 scale helicopter doesn't weigh 1/7th of a real one, it weighs 1/7³ = 1/343th of one. They should've used a much smaller stamp. Distance, area and volume/mass/weight scales differently.

[@peterknutsen3070]

Yeah, I’m surprised Grant didn’t point that out.

[@CZProtton]

@@peterknutsen3070 He knew the myth was bullshit just from thinking about it. So it does not matter. Helicopters are not that easy to crash, otherwise they would be completely unusable. I am quite sure there is probably more difference between helicopter blades just from wear and tear than the weight of a stamp, 0.15 grams. That is absolutely nothing, one helicopter blade is heavy, even on a very light heli. You can make a bullet hole inside one blade of an apache and it will still fly. Sure, that is an apache, but the helicopter mechanics are the same.

[@LaraCroftCP]

In later episodes they never repeat that misstake.

[@JonatasAdoM]

Either Balcony Hawk or Apache uses paper blades over many layers to avoid issues with bullets. The Hueys had issues with blades being hit during Vietnam. Those were metal.

[@GuyDudeman]

wouldn't she have wanted to sell more copies of the mag she was in? Getting it on Mythbusters would definitely be helpful.

[@dgthe3]

@@GuyDudeman By the time the episode aired, the magazine would likely have been of the stands. Magazines typically came out 1-2 months after content was made for them. Mythbusters, I think I remember hearing, was often around 4 months. So even if the episode was filmed the day after the photoshoot, it wouldn't have helped sell more copies. But the actual order of things was: shoot happened, magazine got put out, internet reacted, Mythbusters was filmed.

[@mirabilis]

Free publicity.

[@Goalsplus]

Rock salt! Thanks guys. I was hoping someone would figure out an alternative.

[@NoriMori1992]

41:07 This exact thing happened to me and my lab partner in high school, when we were doing a practice run of this recipe for a class assignment where we had to demo some kind of interesting chemical reaction. I found the recipe online. The teacher didn't have a frying pan, so we used a beaker on a hotplate. While we were heating up the mixture, it combusted and started spewing fire. It was so bad that the beaker melted to the hotplate and she had to throw the whole thing out. We had to open all the windows in the adjoining hallway to let out the smoke. The teacher said it was the worst lab accident she'd seen in 11 years of teaching, and she cancelled the assignment for the whole class and said she was never giving it out again because she didn't want to tempt fate anymore. After all these years, I'm very relieved to learn that this hasn't only happened to us!

[@michaelsaville9985]

It’s crazy that simple baking ingredients can turn on you that fast completely by accident. But, of course, Adam had to take it just a bit too far 😆

[@marinusdebie4421]

8:37 ,looks like airwolf chopper🤗🤗

[@9darkdays]

Grant in the later episodes is called in to teach Adam and Jamie how to fly a remote controlled plane. I wonder if this episode made Grant want to hone those skills. He was already good at remote controlling things, but that doesn't seem to extend to airplanes.

[@Goalsplus]

Possibly the helicopters got better.

[@bopeep8205]

Full 2L bottle of cola on a lathe. That takes the cake.

Adam also had a lathe accident last year i believe, he almost lost a finger trying to clean the lathe while it was on

[@boz7737]

Why did they need multiple takes for this?😂 8:01, the stamps on a different position at 8:05

[@gordonbrinkmann]

I'm wondering if 8000 stamps have had the same effect on the model helicopter if they were all stuck flat onto the blade instead of screwing a big block on it which has much more air resistance...

[@somedude3443]

I could see that messing with the aerodynamics of the blade, for sure. Also, I think a big block bolted onto the blade would affect the rotational balance of the blade more than the aerodynamics... though it certainly wouldn't help that, either

better use for potasium nitrate and sugar is rocket motor

[@BabyMakR]

48:49 Hearing? Try hand. A friend's cousin lost 2 fingers on his left hand to one of these when I was in primary school. Bottle bombs are no joke.

[@ztyy8185]

During Vienam war many huey helicopters lifted up and flown with heavy blade damage, since sometimes they would land cutting space through the brush, branches and vegetation. So I assume one stamp won't do a thing.

[@gordonbrinkmann]

For the salpeter/sugar smoke bomb: never heard that somebody but it in a pan to "bake" it. When we were kids we just mixed the two ingredients and then ignited the mixture with a lighter.

[@cptndltrne]

This is it. This was the first episode of Mythbusters I ever watched. I think I was 4 years old. This is my genesis

My first one was peeing on the third rail. Then one day I finally found them and here we are today.

[@Jayjay-qe6um]

Steve Spangler signed a licensing agreement with Perfetti Van Melle, the marker of Mentos, after inventing an apparatus aimed to make it easier to drop the Mentos into the bottle and produce a large soda geyser. Amazing Toys, Spangler's toy company, released the Geyser Tube toys in February 2007. In October 2010, a Guinness World Record of 2,865 simultaneous geysers was set at an event organized by Perfetti Van Melle at the SM Mall of Asia Complex, in Manila, Philippines. This record was afterward beaten in November 2014 by another organized by Perfetti Van Melle and Chupa Chups in Leon, Guanajuato, Mexico, where 4,334 Mentos and soda fountains were set off simultaneously.

[@PJxpanterx]

[@santiroust1590]

"stamps" are used to balance double blade propellers. Not single blades. Is usually used on drones

[@cejannuzi]

I knew their 4 bottle rocket was going to be duff.

[@flatterkatz]

that stamp thing was so dumb. If it was true, then a speck of dirt, a literal bird poop, would get helis to crash, nobody would be using them. That's like they invested half an episode on the myth "a kitchen magnet on the tail pipe will get a car to crash" and started with toy cars because, oh no, what if it does crash?

[@-droid-j7-225]

Household items -> gets a high pressure methane tank…

[@888johnmac]

using the gas supply from your stove would probably give similar results

[@decvoid261]

The hydrogen crisp bomb works much the same with any flammable gas, was an old goldsmith's workshop prank. Tried it once with hydroxy gas, but the flame can jump several feet, and it is instant and very lethal.

[@PlutoTheSecond]

Were Kari, Grant and Tory testing a myth when Adam used the smoke bomb on them? If so, which one?

[@bam3xs]

Years ago we were at a festival and had some dry ice in the form of tiny pallets with us. On the last day I did basically the same, poured about a tablespoon of it in a bottle and played around with it for like 10 minutes and nothing happened. Then I threw the bottle away as we were about to leave and just seconds later it exploded in such a loud bang. Funny coincidence (or not so funny, depending on your perspective) a buddy was jumpstarting another car and just as he attached the last cable the bottle went off. Poor guy almos crapped his pants. Some people saw it happening and took the last bits of dry ice we had. When asking what they're up to, they said they want to make some bottle bombs and throw them in the portapotties. No idea how that ended though or if they even did it

[@josephtortona824]

They should have used chilled soda beverages.

[@allanshpeley4284]

"Candy" and "soda".

[@Deathbyfartz]

isn't the smoke bomb also pretty much the same recipe used for sugar rockets? 0.o

[@davidkummer7662]

TRY ACETYLENE! Pure, in a ballon, it will shatter nearby windows. If balanced wit O2 it will DETONATE! Plus, you can produce this stuff b dropping Calcium carbide into water, similar to mentos. Don't ever underestimate acetylene(whatch youtube vids on it exploding without O2 in the ballon!) They missed that!!

Even during the original air date, they were using helicopters in warfare, if a stamp could down a gunship, what will AA do?

[@2005Guyver02]

If you don't mind a stomach ache: eat the mentos and swallow them, then drink the cola.

[@kyuofcosmic]

They tested that later on, the reaction does not occur due to the delay between ingesting mentis and cola.

If you thought purified sugar is bad for you? You chose chemical substitutes?

[@chadmrrsn]

Im pretty sure it's the other way around, especially if high fructose corn syrup is involved

[@btf_flotsam478]

Fun fact: the very first artificial sweetener (think alchemy era stuff) was lead acetate, which is just as bad as you think. During the 1960s, when artificial sweeteners that didn't give heavy-metal poisoning was discovered, people had the exact reaction you have, but they have been extensively tested and found to have minimal health effects.
