This is the system for the diving bell, the first underwater diving apparatus used in the 1600sIt would be a heavy metal bell craned down to the sea depths and the air would be trapped inside and water could not enter it, making a tank of air to use for divers.
Do people bath with little candles floating around?
Cue the Spongebob fire underwater meme
If I were to not hold it tight to the bottom of the tub, would the water level rise as the air is consumed by the fire?
yeah, but you can't keep it down there
I'm going to try this, I'll report back 😂
I’m dumb, but I thought putting a cup over a candle suffocates it in essence, hence cutting off the oxygen needed for the flame. How is this possible with the added addition of submersion? Again, please excuse my ignorance
I learnt that this works from Pirates of the Caribbean, when Jack and Gibbs took the small boat underwater upside down and theu could breath
This must be how someone convinced another that a diving bell was safe.
I’m more amazed that we can just casually record videos underwater with our cell phones...
30 years ago, the impressive thing about this clip would not have been the candle 'underwater' but the fact that it is being filmed underwater
This is two videos edited together. It flips to another shot while going down. You can see the candle start to go out and then they switch to a shot where it’s already going down.
“Holy shit, holy shit, holy shit.”—The candle, probably.
will it work with gasoline
Didn't stay long enough for a krabby patty.
Everyone getting scientific but I’m just wondering why the water is steaming.
Now your night light can also go to the seabed and not just your bed
That’s what Jack Sparrow did with a boat to breathe under water
Now try it with a toaster!
What’s up with all the steam coming off the surface of the water? Is the water in the tub super-hot?
For those wondering: this principle was used by early divers by using a metal bell to act as an air pocket for divers to swim longer without resurfacing.
This is how diving bells worked.
When testing the diving time limits of the first submarines, they would dive just below the surface and light a candle. When the candle went out it meant the oxygen was gone and they would resurface before everyone suffocated.
Wow! So there is air in the glass for the candle to burn, right?
That explains SpongeBob campfire.
Why the fuck does this have so many upvotes? 🤷🏻♂️
Omg coool! I see myself trying this in my tub🙏🙏
That’s pretty lit
Old school diving bells
Thanks for checkin that physics still work
Well, it’s not the candle, it’s the cup and the air suction or whatever it’s called I forget, but it seals it inside
I wonder if somehow someway this can be implemented in real life in a larger way.
Welp. I’m gonna make my nephew shit his pants with this trick.
So this is how sponge Bob got a campfire
Y'know stuff like that is why people get burned as witches. Just sayin'.
Another thing people can look up is like the diving bells divers have on some ships for deep dives. The history behind it. People used to use berrels because of the buoyancy they'd drag it down and there would still be an air pocket but obviously the smaller barrel means less dive time because the air would become "bad" in a way so fewer dives before they'd have to come up
Looks like the candle went out before he went further in the water
So wait, why does this work, but not the boat trick from Pirates of the Carribean?
everyone be making scientific analysis and stuff, this is clearly edited, it cuts right after the candle goes underwater
This is how they built the Brooklyn Bridge back in 1869. They lowered caissons into the East river in order to dig the foundations for the towers.
this is awesome
Physics are so cool
