Invisible Ink Research Paper
created by vaporization of liquid which causes expansion of the liquid and therefore making a shock wave. Fireworks are also used in television quite frequently and have a lot of chemistry behind the scenes. This includes the different metals changing the color, the gunpowder to fuel the explosion, and finally the ingredients such as charcoal and potassium nitrate that are what make the reaction. Another common television art and magic illusion is invisible ink. Invisible ink was first used over 2000 years ago by the greek and romans to write secret messages. Invisible ink is used in television to show magical illusions, write secret messages for the characters, and to amuse the audience. Invisible ink also has a very versatile usage going from spy toys for kids all the way to being used in the CIA. The way invisible ink works is by using the carbon compounds in lemons. To make the invisible ink one would paint the colorless lemon juice on a writable surface. The carbon compounds will be absorbed into the material. After the lemon juice is absorbed heat the writing surface, which will cause the chemical bonds to break down which frees the carbon. This will allow the carbon to contact the air and oxidize which changes the writing to a darker more visible color

Dry ice can also be used to help patients who have skin cancer by finding and spraying the area affected with cancer, which could be any irregularly shaped mole or bump. Moreover, dry ice can be used to create fog for film or performances. Dry ice is created by adding Bromothymol to the solidified carbon dioxide to create the color. Next the carbonic acid that is created results in the electrons changing making the dry ice transform into a gas. Finally the infamous cloud that dry ice commonly known for is made due to the water vapor around the dry ice turning into very small pellets creating and exothermic gaseous
