Chromatography. Take a piece of blotting paper, put a tiny drop of dye in the middle and then drip solvent (e.g. water, acetone, ethanol etc) onto the dye blot. The dye will spread out into separate coloured rings.
Paper chromatography separates molecules based on their solubility in the liquid solvent. One end of the chromatography paper is dipped into a solvent reservoir which travels up the paper via capillary action. The samples are placed on the bottom of the paper, above the initial solvent line. As the solvent travels up the paper, it dissolves the samples and carries them upwards. Based upon the samples' solubility in the solvent, they travel proportionally further or shorter distances.

The only disadvantage, like any paper chromatography method, is that the test take a lot of time - typically 45 to 90 minutes.This method also yield little amount of pigments when it comes to the extraction of the isolated pigments. Several tests must be run to gather a respectable amount for further chemical tests.
no Yes it can.Due to the little holes in the filter paper. The holes send through the clean water into a beaker. No it won't. Look at the mixture of oil, water and food coloring.
If you like science Paper Chromatography is something to look into. You can take Chemistry classes to find out different ideas on how to use Paper Chromatography.

TLC. The mobile phase is a liquid, the stationary phase is a solid. Useful for seperating and comparing mobility of solids and some liquids dissolved in the mobile phase by their affinities to the solid phase relative to the mobile phase. GLC. The mobile phase ia s gas, the stationary phase is a liquid on a solid support. same concept as TLC. useful for seperating gases by their affinities to the stationary phase...the mobility can then be compared to known compounds for possible identification.
Depends on: * mass or volume of solvent * type of salt * type of solvent * heat input * agitation of solvent

A single paper bag can take 3-4 weeks to decompose.
paper takes 2-3 weeks to rot!! :)
It takes about 3 to 4 weeks to decompose a paper bag.
The Paper Clip Project took 10 years.
