On December 9-12 the chemistry 1 students at Laramie High School got to tie dye for extra credit.

The students had a period of more time doing tie dye due to the snow day. Students could have come in before school, during lunch, or after school to do their shirts.

But it was one hundred percent optional because it was for extra credit, they had to wear their shirt the following Monday.

“I liked the idea of tie-dyeing shirts for extra credit,” Emma Sliger said.

Tie dye that stores use, usually wash out because the dyes are not chemically able to stick to the shirt.

The students had to get a cotton tee shirt because synthetic, or man-made, do not bond to dye molecules.

Before the students started the process, they had to soak their shirts in a sodium carbonate solution, which should open the cotton bonds so they dye molecules can stick to it and stay there.

The teachers wanted to keep the shirt over night to soak but the students could have brought the in the morning, the longer the shirts soak the better the dye bonds will stick to the shirt.

The chemistry teachers highly advise that the students wear gloves and an apron because the dye is very pigmented, and the sodium carbonate can irritate their skin, the dye is stained almost everything it comes in contact with.

The more rubber bands you put on the shirt the whiter the shirt will be, there are also different designs that the shirt can be put in, like a spiral, the most common design.

Where the students put the rubber bands effects their design, and where their white spots will be, different rubber band designs makes different patterns.

The color in the dye is supposed to interact with the cotton molecules and stick to the molecules and stay better than store dye.

“I love the way my shirt came out and it is so pigmented,” Olivia McCarthy said.

The reason the dye sticks to the shirt fibers because of covalent bonds. Covalent bonds are one of the strongest bonds so that is why they stick.

“To be honest, I did not know tie-dyeing had this much chemistry in it. When you tie dyed as a kid, you did not even think about anything with science, you were just having fun as a kid. Now that there is so much science behind it, it’s kind of ruins the fun behind it. Like now that is has to do with chemistry tie dyeing does not feel the same,” McCarthy said.
