Spirit papers get their name from the alcohols or "spirits" used in the manufacturing process. Typically these were methanol or polyvinyl alcohols and gave the paper a distinctive smell. The spirit papers use a leuko dye affixed to a paper that then reacts to heat, resulting in transfer of the dye to an acceptor. The image to be copied is exposed to an infrared light source which selectively heats the ink of the original. This heat is transferred via direct contact with the spirit people, effecting the transfer of the image. Spirit papers were used in thermal image copiers and old ditto machines. Although they are no longer as widely used since the invention of the Xerox copiers, they remain a staple in the tattoo industry and for some silk screening artists in the creation of stencils.

To make a dam for a science project, you can use materials like cardboard, clay, or playdough to create the structure. You can reinforce the structure with popsicle sticks or toothpicks. Test the dam by pouring water behind it to see how well it holds back the water.
