filtrate
sand is a filtrate it stays behind
To make a paper filter at home, you will need a piece of paper towel or coffee filter. Fold the paper in half, then in half again to create a cone shape. Trim the bottom to fit your container. Place the filter in the container and pour your liquid through it.
Usually, it's used to separate a precipitate from the liquid in the solution. The filter paper is folded into quarters and placed in the funnel. The solution is then poured onto the filter paper, where the liquid filters through and the precipitate stays on the filter paper. The precipitate can then be saved or discarded, depending on which part of the solution you want.
If you mix a dye with a colourless solvent (e.g. alcohol) and place a drip of it in the centre of a round piece of filter paper, the different dyes will "run" at different speeds and for different distances. You will be left with a series of concentric circles which are of different colours.

A Pasteur pipette or glass dropper can be used to drop the solvent onto the filter paper during the filtration process.
Place a piece of Ph paper in the liquid and remove. The color the paper turns will tell you the acid level.
The color that is transmitted through an orange transparent piece of paper would be mainly orange, as the paper is designed to allow orange light to pass through while absorbing other colors.
