Thanks Simon, much appreciated - can you please give an example of a dye that could do this with either an electric field or current? I tried looking it up, but did not return anything useful.

You could move them through a vacuum and separate based on their relative velocities

So from my understanding of glow sticks, the decomposition of hydrogen peroxide provides electrons that excites the fluorescent dye and gives off that classical glow-stick light source. My question is, could one put a DC current over the solution and still theoretically obtain the same...

You could alternatively use a solvent to remove your plastic?

Thanks everyone for your insight- that does make a lot of sense :) Out of interest, if they are made separately, how do you think the body may have been created?

Hello, Does anyone have any idea how the screw conveyers in these photos would be manufactured? http://www.bwsinclair.com/Products/Live%20Bin%20Bottoms.htm It's the variable fin length that I don't understand - could this be extruded? Any clue how it would/could be done? Thanks for your...

thanks Tasp77 and Q_Goest - interesting ideas. I like the idea of carbonation, and of the tap water pressure, but here in Australia we've just come out of a drought and the pressure in our taps has been reduced where I live to save water. Cheers!

Hi everyone, lately I have been wondering how I could make a pressurized tank to test how waterproof my watch is - I am not keen to pressurize air, I figure it would be safer doing it with water. Any idea how you could do this DIY style at home? The best I could come up with is a tall...

I was interested in knowing if my thoughts on this are right or if anyone else has any other thoughts on the reaction of any amino acid and concentrated HCl solution with water as the solvent; As an example of an amino acid such as cystine with an NH2 bonded to a carbon; I was thinking that...

Hi all, I've been playing around with chloroammine gases and have been trying to react them with solids [with some success, but I don't think it is as efficient as I would like]. I am producing a mixture of NH3, NH4Cl, NH2Cl, NHCl2. The ammonia I am not worried about, what I am wanting to do is...

I don't know what a flashcard is but paper is basically a collection of cellulsoic/lignocellulosic material. There isn't much you can do with it alone, but perhaps take advantage of its physical properties like using its ability to reform when wet and its porosity by incorporating impurities to...

Thank you PaulS1950 and chemisttree for your suggestions, particularly chemisttree for your detailed responce. Iam not after anything in particular, rather Iam just trying to find out what possible options there are out there for me to play with. Thanks again!

Hello, I am looking for a reducing agent that will, at least partially, take oxygen out of a small system and will allow that oxygen to evolve if it was exposed to an electric current or given sufficient heat etc. Basically I want something to bind oxygen and allow me to get rid of it at some...

wow, actually you have given me something important to think about. Since then I had gone a different way but I do like what your getting at with melting. Thanks for your help, it was useful to my project =)

Hello, Iam trying to find a material which will fail after a week or so under roughly 2.5 giga pascals. The load will vary slightly but not overly significantly considering the magnitute of pressure. It stays between about 1 to 3 degrees celcius and stays in a non-oxidising environment. The...
