Why do some crayons float while others sink Which colours float and which wont
All CRAYOLA Crayons are made from paraffin wax and colour pigment. The crayons vary slightly in weight due to the amount of colour pigment added to produce a particular colour as well as the density of the powder pigment itself. Certain colour pigments are very light while other pigments are very dense. It would not be accurate, however, to say that all dark crayons are heavier than other colours. You can test this by doing an experiment to see which Crayola Crayons float and which will sink.

In 1900, prior to the introduction of Crayola Crayons, we produced black marking crayons. Today these are known as Staonal brand Marking Crayons and are used in many industrial settings. These crayons were created with dry carbon black and different waxes. The first box of Crayola Crayons was produced in 1903 as an 8 count box. It sold for a nickel and contained the colours red, orange, yellow, green, blue, violet, brown and black. We provide extensive information about Crayola and our products on our sites. A history timeline can be found on the Crayola.com web site at our history.
In 1903, we introduced the first box of 8 Crayola Crayons and sold them for a nickel. Included were the same 8 colours that are found in an 8‑pack today: red yellow blue green orange brown violet (purple) black.
In 1958 the box of 64 CRAYOLA Crayons was introduced. It was the first package to include a built-in sharpener design. We continue to manufacture this package design today in the 64 and 96 count Crayola Crayon package.
In 1993 we conducted a poll to find out the most popular colours in America. Blue was voted the most popular CRAYOLA Crayon colour. Rounding the top ten were red, violet, green, carnation pink, black, turquoise blue, blue green, periwinkle and magenta. In 2000, we did another Crayola Colour Census, and blue again reigns as number one!
