Toluene formerly known as toluol, is a clear, water-insoluble liquid with the typical smell of paint thinners. Title: Squid Ink; Alternative Marker
Problem: Is there a possibility that squid ink can be used as a marker?
Hypothesis: The squid ink can be used as an alternative commercial marker because the squid ink can serve as the toluene or the ink. I. Squid Ink
Cephalopod ink or known as squid ink is a dark pigment released into the water by most species of cephalopod, like squid, octopus, and cuttlefish. The squid is released from the ink sacs that is located between the gills of the species and is dispersed in the water when the animal is threatened. II. Markers
Marker is a type of pen which is darker and it has its own source of ink. Its tip is usually made of porous, pressed fibers such as felt. A commercial permanent marker consists of a container may be a glass, aluminum, and plastic, and a core of an absorbent material such as felt. This filling serves as a protection for the water-proof ink. The upper part of the marker contains the nib that was made in earlier time of a hard felt material, and a cap to prevent the marker from drying out. Until the early 1990s the most common solvents for ink were toluene and xylene. These two substances are both harmful and characterized by a very strong smell. Xylene
Xylene are usually found in small quantities of gasoline and airplane fuels. The mixture is a slightly greasy, colorless liquid commonly encountered as a solvent. It is also one of the chemical components of
markers. Squid Ink; Alternative Marker Background Information To find out if squid ink can be a replacement for commercial pen as marker. 1. Empty filler of used case of marker. Procedure Objective Materials The materials needed are empty marker container or straw, gloves, foam, scissors or scalpel, tape, 3.5 oz. empty small container or jar, fresh squid, , white bond paper and tissue paper. 2. Cut and form the foam of exact measurement of the used marker filler
or straw. 3. Get the ink sac from the squid and squeeze
the ink into the jar. Materials 4. Spread the squid ink above the foam and wait for 15 minutes for it to be absorbed. 5. Insert the soaked foam into the empty marker case or the straw. 6. Close tightly and test if it can be an alternative to commercial marker by writing it on a white bond paper. Analysis of Results In this investigation, we learned that squid ink can be an alternative for commercial marker. Based on our observation, the squid ink is a thick and dark color water based material. The result of our investigation is a softer, more delicate and darker foam. The foam quickly absorbed the squid ink. Conclusion It turned out to be more useful and an environmental–friendly product. The foam became softer. It became harder to hold because of its delicateness. It was hard at first to make it, but if you know all the procedures it will be easier for you to make it. It is also more environmental-friendly because the squid ink is natural while the commercial marker consists of compounds like toluene that adds impurities to our environment and xylene which is carcinogenic or can causes cancer. Recommendation We recommend pure squid ink because it is environment-friendly. Ordinary markers has xylene and toluene content which can cause cancer and are chemical components of fuels that can cause dangerous effects in our surroundings. Acknowledgments We would like to thank our parents for helping and supporting us from the first day we made our Investigatory Project. We also like to thank our classmates namely Erika Nidea, Lyka Terrado, Andrea Alulod, Akiko Orui, Jade Mosot, Julienne Labrador, Nyah Regalado and Lian Terrado for being there when we need something. We also thank our teacher, Ms. Christine S. Romero for helping and guiding us. We also like to thank our school, Diliman Preparatory School for letting us explore this investigative project. And lastly, we thank the Lord for giving us the idea of this project and the wisdom to complete it. Advantages of Xylene
Xylene is a powerful solvent. It thins lacquers and softens some paints. It has a slower evaporation time than other products, Disadvantages of Xylene
When smelled, it can cause headache, dizziness, drowsiness, and nausea. It can also cause sleepiness, stumbling, irregular heartbeat, fainting, or even death. Xylene vapors are mildly irritating to the skin, eyes, and lungs. If liquid xylene is held against the skin, it may cause burning pain. Liquid xylene splashed in the eyes can damage the eyes. Generally, the more serious the exposure, the more severe the symptoms. Advantages of Toluene
It is relatively inexpensive, it is readily available in any quantity and purity, and It is not a listed carcinogen. Disadvantages of Toluene
It is often not a really good solvent, it is a VOC (Volatile Organic Compound) and has a fairly low exposure limit. Abstract Our group thought of a project that is beneficial to students and a project that is environment – friendly. we came up with the project, “Squid Ink; Alternative Marker”. We used a lot of materials like foam, squid ink, gloves, empty marker case or straw, scissors or scalpel, small container or jar, tape, tweezers and spoon, and dissecting pan. The foam we used is flower foam. We got the squid ink from a fresh squid. We worked on our project in our school’s science laboratory. When we are making it, we are very challenged. After dissecting it, we squeezed the ink out of the ink sac. We spread the squid ink on the foam and waited for 15 minutes for it to be absorbed. We put the inked foam inside the straw or empty marker case and quickly tried it. the result is a dark ink running out from the empty marker case.
