Exciting water mist
« on: November 14, 2012, 06:09:27 am »
Today in chem lab something happened that blew my mind. After all this time experimenting with water and reading forums I have never come across something like this.
In lab we were identifying substances by the wavelength they give off when electrons are pushed to a higher energy state and then return to ground state. For practice, we used excited water vapor! It looked just like a neon light. The power supply was only 5kv ac. I don't know if this thread will go anywhere but i thought it was cool!

Hi Dave,


Nice experiment. I never heard of this. Looks like something with potential for our projects.
Can you tell us more about it?

This will lead to the Dream Cell :)

Imagine being able to take an ultra sonic transducer to make the mist mouted in the bottom of the same o.d.s.s.tube with a fan the same o.d. just above the water level line.Next we need a butterfly type check valve..... now the magic... we learn to prevent the stuff enerting stable state ( emission of energy ) we somehow rearange the energy and make the make a gas :)  alla the " dream cell " lol   well  the lab would be a fun place to be right now ;)

Exactly!
Thats a good possible option!

I will see what further information I can get. I won't be able to talked to my professor for s reasonable amount of time till Monday.

I do know that the tube filled with mist was prepared in a lab somewhere and we are just using it to look at emissions. I believe the tube was prepared simply my filling it with mist and then sealing it. After its sealed the volume is fixed and it would have to creat a vacuum to condense which it can not do at a reasonable temperature. I will get the specifics and anything else I feel is useful as soon as I can.   

Newguy, I agree!

I had some time after class today to find out a few things. My professor thinks the tube is at less than 1atm which seems reasonable. As for the operation, it works just like a neon sign. A small amount of current is being past through the gas at a high voltage. The lab specifically designed it to work properly with the power supply. If anyone has any other questions, I will try to pass them along.

David, I think a great start with you ,your professor and that lil lab demo would be to ask proffesor if it could be possible to prevent the energy emmission via magnetic,electromagnetic,catalisis... any  imaginable way..... next quest I think would be rearranging the available energy via any way imaginable to form A gas... any stable combustable gas. for some reason i still want to think carbon atoms or nitrogen atoms will need to play some role in the thing but dam i would love to have a proffesor available and a lab an all that stuff .Molecules,energy,ions,and atoms... whoo hoooo :)

still pondering about this thing and questions to ask.....    why does it take  vaccum to make it work? will it work at all with out vaccum?
