As it says in the clip :

Don't do this at home folks. Just DON'T.

I can't get the link to work. It creates a fault in Explorer, and kills my computer.

Sorry to hear that Baldrick, old bean.

 

Ask Pin or one of the other computer boffins - they know how to sort out links & stuff.

Good luck.

I knew I could use the microwave for something else instead of warming beans up

this sounds stupid but may i ask what is plasma

[dazza]

In physics and chemistry, a plasma is typically an ionized gas, and is usually considered to be a distinct phase of matter in contrast to solids, liquids, and gases because of its unique properties. (Plasma corresponds remarkably well to "fire" in the four classical elements, fire, earth, air and water). "Ionized" means that at least one electron has been dissociated from a proportion of the atoms or molecules. The free electric charges make the plasma electrically conductive so that it responds strongly to electromagnetic fields.

 

This fourth state of matter was first identified in a discharge tube (or Crookes tube), and so described by Sir William Crookes in 1879 (he called it "radiant matter")[1]. The nature of the Crookes tube "cathode ray" matter was subsequently identified by English physicist Sir J.J. Thomson in 1897[2], and dubbed "plasma" by Irving Langmuir in 1928 [3], perhaps because it reminded him of a blood plasma [4]. Langmuir wrote:

 

"Except near the electrodes, where there are sheaths containing very few electrons, the ionized gas contains ions and electrons in about equal numbers so that the resultant space charge is very small. We shall use the name plasma to describe this region containing balanced charges of ions and electrons."[3]

Plasma typically takes the form of neutral gas-like clouds or charged ion beams, but may also include dust and grains (called dusty plasmas). [4] They are typically formed by heating and ionizing a gas, stripping electrons away from atoms, thereby enabling the positive and negative charges to move freely

 

Just a quick explanation of the top of my head

good man Dazza , it would have taken me a week to type that lot.

Hi "me and my lad"

 

Yes - I've seen the CD-in-a-Microwave,

and I've heard about the Christmas Lights - but never seen it.

Do you have a clip ?

 

Best wishes,

PLASMA

 

asked Google "define:plasma"

 

most suitable of many answers as follows :

 

A plasma is an extremely hot gas that is composed of free-floating ions (atomic nuclei stripped of some electrons - making the ions positively charged) and free electrons (negatively charged). A plasma behaves much differently than a neutral gas, and is considered the fourth state of matter. A plasma conducts electrical currents. Stars are composed of plasma.

Thanks pin.

bookmarked that for further study tomorrow.

 

you are real star (plasma).

 

Got any more?

AWESOME.

 

More fiendish amateur science !!

 

 

thanks pin.

You need to catch "braniac" on telly, they are to the microwave what Clarkson et-al are to the caravan. The small one from TopGear presents it I think.

Do you have a clip ?

havent got a clip sorry, did it myself a few years ago.

it will knacker the cd and the bulbs but its worth it for a laugh !!

What about gold fish in bowl.............................

 

Blimey, we will be running low voltage lighting from potatoes next..................or is that with a lemon....I cant remember...

 

 

One for you all to try is Glass cutting.

 

 

You will need to heat a bowl of water to 30.06 degrees C, A digital thermometer is essential for this to work. The temp fluctuation must not be greater than .02 degrees either way up or down otherwise it will not work.

 

Take a sheet of thin glass, around 4mm thickness. emerse into the water and ensure that his is done for about 1min at the previously stated temp, an additional heated bowl of water will help to maintain the temp of the water. Again be careful that the temp does not fluctuate to more than .2 degrees.

 

Using a pair of VERY sharp scissors, something like victornoix or other type of similar sewing scissors used by crafty type persons you should then be able to make small and slow incissions into the glass. Start with the scissors fully opened but close them slowly and deliberately onto the glass.

 

Keep an eye on the temperature gauge and make sure that you are not going above or below the .2 degree levels and you shoul be able to make it all the way to the other side of the glass.

 

I should mention that you should take care, and where necessary use all the correct safety equipment, goggles and hand protection.

 

It wont work on any other glass thicker than standard "unlaminated" 4mm glass.....Toughened glass will not work. Neither will tinted or double glazed units.

 

try it and see for yourself.
