MAJOR Thought of the day.... It'll make your brain hurt, trust me.

Monitors, those behemoths of CRT fame. they are filled with vacuum right? And that's alot of nothing in there right?
Would a monitor sink or float if thrown in a lake? What if you removed all the junk electronics?
Think about it... stuff that is less dense than water floats right? And what could be less dense than a vacuum?
Consider it a science expireiment, I'll hafta find me a handy dandy lake, and an old monitor to expirement with, but I'm highly curious as to what will happen.

Any one have a junk 21 incher I could compare to a 14 (figure a 21 inch will have more tube voluume empty and float better.

I seriously hope this guy is joking. Why dont you throw your monitor in the lake but dont come crying back to us when you find out what really happens

He said it's an "old monitor".

The question would be whether the glass of the tube weighs more than the equivalent volume of water.

I think after reading the title your post has to be the major disappointment of the century :frown:

No no, think about it, that crt tube is all empty space right? why the heck does it weigh soo stinkin much, I've got to find my junker and see...

 

[Viper GTS]

why the heck does it weigh soo stinkin much

Because it's thick glass, & glass is heavy as hell.

Word of advice, make sure that monitor is plugged in when you toss it in the lake. Otherwise it wouldn't be a proper test.

I did some quick calculations using data from the NEC web site.
The density of a 17 incher is about .22 kg/l. A 19 incher is about .24 kg/l.

 

[ArkAoss]

napalm, whats the density of water? 1.0??

Viper GTS: I couldnt agree more!

This is false advertising at its worst.

King: not really it did make my brain hurt. But not for its depth, just for its stupidity. No offense Ark.

I don't think it's the vacuum that's really important. An equivalent volume of air would weigh what, a few ounces, right? You could probably fill the CRT with a light alcohol and it would still float.

That's not my point...

Let's say the CRT is a perfect sphere (for the sake of simplicity). The outside diameter of the sphere is 18", while the inside diameter is 16". So basically you have a 1" thick spherical shell of glass. The question is whether that portion of glass weighs more than an 18" sphere of water would weigh.

exactly viper, that is the question, would the spherical shell of glass weigh(displace) more than the volume contained within.
