Apple as Invisible Ink

7. Tape the strip to a pencil and rest the pencil on top of the jar so that the strip hangs into the jar. The goal is to have the end of the chromatography strip just touching the surface of the solvent solution, with the colored dots above the surface of the liquid.

The apple I believe serves as a symbol of the pain and hurtful words issued to Gregor by his family. The apple in his back came about as a result of the pent up fury of his father. One can assume the apples were the hurtful words of Gregor’s father as he was frustrated with his son’s metamorphosis. I think the apples here serve as a biblical allusion like the apples of the Garden of Eden which caused sin to be introduced into the world. The apples or the eating of the apples by Adam and Eve caused pain and death, just like the apples where one lodged in the back of Gregor, causing an infection leading to his death.

Several activities take place in the evening, but the most antipated one by far is going trick-or treating. Both children and adults dress up in costumes and walk from door to door collecting candy from their friends and neighbors. This ritual is from Samhain, an ancient Celtic gala that marked the end of the harvest season and the start of a new year. The Celts thought that the spirits left their world to interact with the living and so wore disgues and made food offerings to try to appease them. Bobbing for apples is another modern-day Halloween custom that has Celtic roots. Apples were the fruit of death. The Celts believed that the departed had to undergo two trials before they could make it to heaven. “The water ordeal is the familiar bobbing for apples, while the fire ordeal involves trying to take a bite out of an apple attached to a hanging stick which also bears a lit candle” (Kondratiev, par. 12). Playing this game attuned the dead to the needs of the living over the course of the following

The apple will fall from the tree and decompose on the ground leaving the seed. The seed will work its way down into the soil below it. The seed will need water to help it grow. Over time, the seed will grow into a plant which will eventually grow into a tree! The apple tree will begin to produce blossoms. These blossoms will turn into

The first tradition that I want to talk about is the Christmas tree. Every year, Iand my family go into the bush to get a tree. We find one that looks good and chop it down and use the top. It’is a lovely tradition. The history of the Christmas tree is really vast and substantial. A look at the history of the tree only shows how extensive this history actually is. According to History.com Christmas trees used to

There is something special about packing the family for an afternoon at a local orchard with its sweet, alluring scent, trees filled with ripe red fruit, bags overloaded with the best apples to bring home and a sampling or two of the fruit direct from the trees! And, let’s face it there are few things better than biting into a crisp, sweet, perfectly juicy apple!

In The Giver, the Apple symbolizes change. For example change occurs in the story when Asher and Jonas are playing catch with it but then to Jonas the Apple seems to change. Lois Lowry writes,”Suddenly Jonas had noticed … the Apple had changed” (30). This happened because Jonas was seeing color for the first time, specifically red. It introduces us to the fact that he can see “Beyond”.

British spies used to use semen as invisible ink but the practise stopped due to old letters beginning to smell.

Ink can be defined as a pigmented substance which can be used to create markings on a surface; however, over the course of history ink has been composed of different materials. The earliest form of ink known to historians, Indian Ink, was created around 2500 BC by the Chinese. This ink was a mixture of soot from pine smoke, lamp oil from animal skins, and musk. Scholars and scribes used this it to record information such as farm accounts, religious texts, and possessions and the people who owned them. Further down the timeline, Europeans created Iron Gall Ink from crushed gall nuts, iron or copper salt, and comarabic (which held the mixture together). Because of its durable nature, people such as Bach, Leonardo Da Vinci, and Van Gogh used it

In my experiment i heated up lemon in different ways and tried to make the lemon juice shoW up on the paper. I originally thought that if i used a blow dryer or a microwave it would work but it did not so i decided tO UsE a skilleT and my ovEN. The oven worked best with you being able to read 100% of the word that was in the oven and others trailing with you only being able to read 60% of the fire and 50% of the skillet. A common pattern was that the more space it heated all together the better it can be read.

Invisible Ink can come in many different forms. Inkvisible ink, by definition, is “Ink that is colorless and invisible until treated by a chemical, heat, or special light” (thefreedictionary.com). Invisible ink, also known as sympathetic ink, can be bought commercially or made at home (thefreedictionary.com). The effectiveness of invisible ink depends on what its chemical components are. Lemon juice is a commonly used liquid for invisible ink, as it is readily available and can be read using heat (scientificamerican.com). Lemon juice is acidic, and once dried, burns faster than the surrounding paper, thus turning a brown color once exposed to heat (scientificamerican.com). This kind of invisible ink can be prepared at home almost instantly.

I will use ‘effectiveness’ to refer to the extent of red stamp ink stain on cotton
