The movement of ink dyes on paper is influenced by their solubility and affinity for the paper's fibers. Dyes that are more soluble in water tend to travel further up the paper as they are carried by the moisture, while less soluble dyes remain closer to the bottom. Additionally, differences in molecular size and polarity can affect how quickly and far each dye moves through the paper. Consequently, this results in a separation of colors based on their chemical properties.
For a 2 paper-band kite, 28! 4 for the up-rights, 8 for the top an bottom of the paper-band on top, 8 for the top an bottom of the paper-band on the bottom, now you need 4 cross pieces for the top & bottom of the top paper-band and 4 cross pieces for the top & bottom of the bottom paper-band. If my math serves me, that's 28.

The solvent rises up the chromatography paper (blotting paper) by capillarity. When the solvent reaches the "spot" it dissolves the mixture of coloured chemicals. There is now a solution; this is a mixture of solutes dissolved in the solvent. The molecules of these different chemicals are all different sizes. The simple explanation is that the smallest solute molecules travel almost as quickly as the solvent molecules and so get carried to the top of the chromatogram. The largest solute molecules travel very slowly and stay near the bottom. So some of the coloured chemical travel further than others.
To fold a piece of paper into an envelope without using tape, follow these steps: Fold the paper in half horizontally. Fold the top corners of the paper down to meet the center crease. Fold the bottom corners of the paper up to meet the center crease. Fold the bottom edge of the paper up to meet the bottom of the triangle created by the previous folds. Tuck the top flap into the pocket created by the bottom fold. Your paper is now folded into an envelope shape.

To make a book cover, cut out the bottom panel of a paper bag. Center your book on the remaining paper. Crease the top and bottom of the paper corresponding to the top and bottom of the book. Fold the creases in. Slip the two ends over the front and back of the book.

A company letterhead is a standard piece of paper that is used for all business correspondence. The letterhead usually has the logo of the company along with address, phone, and other contact information at the top or bottom of the sheet of paper.
You place the paper in the bottom left corner of the scanner.
To make a 3D paper star decoration, you can follow these steps: Start with a square piece of paper. Fold the paper in half diagonally to form a triangle. Fold the triangle in half again to create a smaller triangle. Fold the top corners of the triangle down to meet the bottom edge. Fold the bottom corners up to create a diamond shape. Fold the top point of the diamond down to the bottom edge. Repeat on the other side. Open up the folds slightly to create a 3D star shape. Secure the folds with glue or tape. Hang or display your paper star decoration.
