What's up everybody welcome back to my laboratory where safety is number one priority,
and today what we're going to do is, what will happen if you put light bulb into liquid nitrogen?
Lets find out!
So first you're going to need light bulb and then we are going to bring out a towel.
Put it under towel like this.
And then carefully.
I need to break the globe.
Whoo!
Dang it.
Too much.
You see I broke the filament.
So that's not going to work.
You see how this filament fell apart.
So I need to do it a lot more gentle.
It's a lot harder than it looks to break a light bulb.
I hope it worked.
Dang it. I broke the filament again.
But this time instead of heavy I'll get sharp and see if it actually works better.
Looks like it worked better but.
Did the filament survive?
Yes, filament survived.
This is very sharp, I need to
break it all the way.
Do you see how all the filament all intact?
See that layer of wire?
It did not get broken.
That's what we want.
See right now its unplugged?
What I'm going do is grab this
broken light bulb and put it on here.
Kids, do not try this at home.
This, if I touch here and this plugged in it will shock me very much.
Make sure.
Do not try this at home and this one is unplugged.
If you really want to try this, ask adult's permission. They will help you.
Then right here, on and off switch.
Then we're going to pour liquid nitrogen in the beaker.
Boom!
It's boiling right now a lot so.
Look how beautiful it is.
Okay liquid nitrogen settled down.
We're going to get our light bulb.
Then I'm gonna turn it on.
And place this light bulb into liquid nitrogen.
And then I'm gonna plug in the wire.
And lets see what happens.
Isn't it amazing?
It's turned on but it's not blowing up.
How crazy is that.
How cool is that.
Broken light bulb in liquid nitrogen and it's not burning out.
It just turned on
and
as you know
filament is hot
but
liquid nitrogen is super cold.
How come it does not burn out.
Super hot and super cold.
And it does not burn out.
Pretty amazing, huh?
I love it.
I can watch this all day.
And now I'm gonna take it out and see what happens.
Boom!
And it burnt out.
Crazy, huh?
I'm gonna lay that down.
Carefully unplug it
because I don't want to get
shocked with the electricity.
Now that it's unplugged, its- carefully
to unscrew it.
I feel like I have to try this one more time but in a dark room,
just to see what it looks like in the dark.
There you go.
We break the filament? Oh no that's the whole light bulb.
The filament is still inside on this light bulb.
Well, that's weird.
Look! filament didn't break, thats so- that was cool.
Wow! Skills!
So we can still try to use this different filament, different light bulb
into here, let's see what happens.
Put a little bit more liquid nitrogen in there.
Woah! This one is a lot brighter.
Look how crazy that is.
Wow!
I can watch this all day, this looks so awesome, I love this.
So now let's pull it out and see what happens.
Look how bright it is.
Boom!
And it burns out.
As you can see now it's unplugged, now it's safe to
open it up.
Alright, guys! This is pretty much it, let me know what do you think in the comments below.
