Through a tough process, we finally created our end product – The Impeccable Glue. To reach this, we had to first brainstorm what we wanted our product to do and it’s characteristics. When we were first designing our polymer, we decided that the end product should be moldable, a bit sticky and harden overnight. We all received a sheet of paper, with the information about all the different characteristics each material contributes. I had picked corn starch because I wanted something less watery. I picked PVA solution because I wanted something sticky. Another thing I chose was liquid starch to add a little bit of liquids to the prototype. The last thing I chose was guar gum, to add a bit of elasticity to the polymer. When I was making all of the different prototypes, I realized that making a polymer with all of those characteristics was hard. I had tried a few different prototypes and had then turn out too slimy, too sticky, too bouncy. Sometimes it would be perfect; however, overnight it would harden and break.
While making the different prototypes, I learnt what ratio of ingredients I would need in order to make the polymer a certain way. I learned that too much liquid starch causes a much slimier polymer, so you need to add more PVA solution and around the same amount of corn starch to create a sticky moldable polymer. I also discovered that when making the guar gum, the water and guar gum just weren’t mixing properly so it didn’t mix in well with the polymer. So instead we would add dry guar gum straight to our polymer. It mixed way better and worked really well.
On presentation day, I learned that most polymers won’t turn out how you want them to. Sometimes something unexpected will happen and surprise you. Also you can’t always have all the characteristics you want in a polymer, sometimes you have to compromise. But overall, the experience was great and our polymer ended up doing what it was supposed to.

Murder of the Doctor is the talk of the town for a few days. Suspicion sits saliently like toxic fumes resting above Sawyer’s town. In the book The Adventures of Tom Sawyer, by Mark Twain, the rising action and climax bring the heat. Muff Potter and Injun Joe were the only people who were known to be there that night. Nobody thought that Huckleberry and Tom were sitting silently in the shadows. They saw Injun Joe murder the poor Doctor, but everyone put the blame on Muff when they found his knife, the knife that killed the Doctor. Though the accusations were false, he gets sent to prison. At the trial, Tom cannot stand the fact that an innocent man is suffering for the nefarious act performed by Injun Joe. Filled with confidence, he tells the story of what he saw on the night of the murder. While Sawyer speaks, Joe cleverly escapes the courtroom. Tom, fearful and scared, worries that Joe would murder him. Nothing happens for a few days, and Tom soon forgets about all his concerns. A few nights later, Tom and Huck are hunting for treasure, when a disguised Injun Joe catches their eye. Under his arm is a chest of money which the boys are keen to find. The next day, Becky’s parents arrange a picnic for all the young kids in town. When all the kids headed back from exploring the cave near the river, Tom and Becky never made it back. The two kids lost inside the cave soon discover Injun Joe was also inside the same cave. Terror strikes through the two, how would they get back?
In my series of tweets, I was hoping to portray the desperateness in the kids voice. I hoped to portray the sense of two kids lost in a cave then discovering they were with a murderer. It follows the story line of Tom and Becky first getting into the cave, then getting lost. Another tweet describes discovering Injun Joe was hiding out in the cave. After all that trauma, the tweets continue with Tom and Becky tweeting together, praying for the best.
