The way to make thermite effective with a safe... you have to light the thermite that's against your surface first and let it burn upward. Lighting the top especially on a mound that big, the metal don't start getting melted until the very last couple of layers. Next time fuse light it on the bottom against the surface as it burns upwards the heat stays at the surface that you're trying to penetrate
Funny story about this day behind all fake money information is that people got really angry on our Instagram story about this day. We got tens of messages complaining about destroying shitload of money :D And then when we said that it's fake we got even more complaining about that it's illegal :D So I wanted to but that clearly there before shit load of angry RUclips comments :D
IIRC gasoline won't ignite thermite. If it's like matches, they don't get hot enough, which is why thermite is usually ignited with magnesium strips or sparklers.
imbok Stupid test, dislike even before completly watched. Why they did you put thermit on safe not under? Heat goes up not down they are idiots😂😂😂... Do they try fullish peoples??? 🤷♂️ Meaby they self are not competitive? Only small part of heat safe gets😑 High level😂👍
these Finnish people will never stop to surprise me, what they have to use to make themselves and their surroundings warm. Excellent vid as always, life is way too short not to try some weird crazy things.
That's really good idea! I saved the safe in case that we need two for explosion video but we manage to do it with the first one so I can do part 2 for this video where I fill this one up with thermite :D

The thermite won't have much oxygen to burn, so I think it will burn all, but not as intensively. The opening might be very dangerous, you should really know that all of it has burned . because when the door opens, and oxygen rushes in and ...
Does anyone remember “the anarchist cookbook” from back in the day? I remember reading about thermite in there when I was a kid in grade school...I’ll never forget the description it gave. It said a “nickel-size pile” would burn through the hood of a car, the engine, the axel, then the concrete below. I’ve wondered if that was true my whole life. This was clearly way over-exaggerated in the book. Thanks guys. 👍
The Anarchist's Cookbook is infamous for having inaccurate recipes or recipes that are more dangerous than other methods. The later the printing is, the more likely any given recipe is wrong or unnecessarily dangerous to the creator.
proper thermite burns at 3104 degrees celsius. enough to turn hardened crucible steel to melted butter in a matter of minues. HOWEVER, this is where we need to take time in account. for thermite to eat through things, time is needed. (in the anarchist cookbook it also stated that the nickel sized pile would burn for up to 12 hours. time is a factor)
You need a very high temperature to ignite thermite, you could put it through a candle flame and absolutely nothing would happen, so he was not being that risky
Thermite is also good to melt steel beams and cause them to buckle and combined with explosive charges its great to cause tall buildings or skyscrapers to collapse at free fall speed in a controlled demolition,especially if its nanothermite
"And for today's extra content: Flexing with the prop money. We are don't have Mr. Beast's filming budget :D" I actually laughed when I saw the Mr. Beast reference
I don't think they teach you much about thermite in explosives engineering school, they just teach boring legitimate uses like removing bedrock and stuff.
None of these idiots know's shit about thermite.... if they did, they could've easily melted through this safe within a couple seconds with the amount of thermite they had!
It would’ve gone thru really easy if you had it situated correctly. Termite isn’t meant to be used by just putting a huge pile of thermite, you have to use certain metal forms to keep it in one area to Concentrate all the heat in one spot instead of just letting it pour all over the safe.
shape charge that's what is missing. Those pile load of termite releases enought energy to cut throught the steel wall but the energy is not shaped in right direction.
I really thought Lauri would try to cram all the thermite into that experiment. If you didn't know thermite was coming, please binge watch all of the BTP videos. They're fantastic.
Definitely looking forward to the explosives. Your approach is always fun and special for these videos. I treated this one as a good early birthday present yesterday.
Before seeing this my prediction is: The thermite will go sort of everywhere but where you want it unless you have something like a big clay thing to direct it exactly where you want it. It may also burn too fast and splash out even if using a container.
Very cool: But still I have to request... As heat goes upwards rather than downwards, I would like to see thermite _under_ the safe instead of on top :))
God damn it now I'm just thinking of the plane scene with Bane where he says "Calm down doctor, now is not the time for fear. And heeeere we goo" and I can't get it out of my head
So much of the thermite just fell off when it started burning. I think if you had less thermite and covered it better to hold the heat in it might have gone through
Hello. Like the Video but a small tip for working with Thermite: You have to place something on it that directs the heat down, like a ceramic plantpot. The way you used it most of the heat just goes to the sides and up into the air. But when you direct the heat down, that safe wouldn't stand a chance. Saw vid where they melted a hole in a safe using only a quarter of your thermite. It even blew it open(Burning all the content). Regards, Florian
_"When you mix fuel, metal oxide and metal powder in just the right way, it burns at 2000 degrees Celsius. Hot enough to cut through nearly any barrier known to man. Throw some C4 into the mix, and you've got one hell of a combination."_
For those who are interested, thermite is used by railroad companies to join tracks by melting metal into the void. That is serious stuff! It is really super for starting your barbecue!!
Most military used grenades as I remember are Thermate (AN-M14) is what's written on the side of the can, the grenade generates short bursts of very high temperatures (liquid like lava) focused on a small area for a short period of time (40 seconds). It will melt a hole right through a 2" inch solid metal plate similar to the thickness found on a manhole cover.
Awesome! You should try it again, but put the thermite in a terracotta pot with a ball of Al foil plugging the hole. The pot contains and focuses everything, and the plug only melts out once the reaction has really started going. It's similar to how they fuse railroad ties.
www.biltema.fi/en-fi/home/safety/security-boxes/safe-fireproof-2000033385 I'm guessing that Biltema doesn't manufacture any safes themselves but at least they sell them.
I'm not sure you can compare that to a house fire which has much higher energy than this test. Yes. Thermite is way hotter. But this was only 30 seconds.
If someone HAS to store their thermite on top of their safe then at least this safe is good for that. But then again maybe a box made of concrete is fine too.
I remember setting off a thermite reaction in a Mason jar on a boulder in a stream near my house in 9th grade. Scared the piss out of me the Boulder still has slag glass on it 5 decades later. A warm rush of memory thank you

That actually surprised me. Thought the thermite would destroy it. They need to try that again but using a large ceramic flower pot with a hole in the bottom, sitting on the safe so the heats more concentrated.
Really enjoy these videos but also in my area of Canada all the old neighbors spoke Finn and the accented English is very familiar to me. Makes me smile and remember.
Used to use thermite to weld ground lugs to base plates on columns to basic materials processing plants. Crazy hot. Thanks for sharing this video. Everyone stay awesome,
