As I sit on my bed, with nothing to do, my mind is suddenly filled. What can I do with all my JUNK? I search in old dusty boxes, underneath my bed, in my closet and take a look at old picture frames, memories that have been sitting aside for years. What can I do to make it all come together? As I think, look around, and think again, I say quietly to myself, “Why don’t I create a scrapbook?” Scrapbooking is a great way to preserve memories and pass them down in a creative and unique way. When a person
Thermoset polymers contain no set arrangement of chains and as such they can be classified as amorphous i.e. they contain no distinct crystalline structure [3]. Thermoset materials are formed from a chemical reaction of a resin and a hardener or catalyst and this reaction is irreversible and produces a hard and infusible material [4]. Cured thermosets will not become liquid again if heated but above a certain temperature their mechanical properties can change substantially. The temperature at which

An organic adhesive such as wheat paste could deteriorate if exposed to certain chemicals or conditions. Glue sticks may not have the permanence required for the life expectancy of the artwork. The main point is to test out the adhesive product being considered to make sure that it will be suitable for the items the artist
If you either put on a Band-Aid or stuck a Post-It note on your window you have encountered adhesives. Some inventions have given birth to other inventions, other inventions have found new uses. This is the case of the family of cyanoacrylates. In my house when something was broken my dad would reach for the Superglue or Gorilla Glue. In a matter of seconds the plate or cup was fixed good-as-new. Before the invention of these products I would have used Elmer’s glue and hoped after a long wait
In the competition known as Science Olympiad, there is an event build called “Boomilevers.” This event is comprised of building a structure to be attached on one side to a wall and bear the maximum weight possible on the other side, while the structure itself weighs as little as possible. The Boomilever is a long standing Olympiad Event and requires acute attention to detail and a critical mind in architecture in order to achieve the maximum efficiency score possible. There are many limitations and
To make the homemade eyelash adhesive glue you will need ½ tsp. of sugar, 1 drops of honey, 3 tbsp. of water, 1 drops of non-toxic white glue and a small cup. You can find all of these products in your local grocery store. The first step to make the homemade eyelash adhesive glue you need to pour all the ingredients into your small cup. You then need to mix the ingredients together till you get a yellowish liquid it might be slightly gritty. Next, you have to let the mixture settle for 2 minutes
in depth look at the use of hardwoods, and softwoods in the manufacture of outdoor furniture. This brief target audience is technology studies students, teachers, and will specifically investigate safety aspects, structure types and availability, adhesive properties, environment issues, and durability. The hardwoods considered in this report include Jarrah, Spotted Gum, and Tasmanian Oak. The softwoods considered are Radiata, Calantis and Hoop Pine. HARDWOOD Hardwood is timber that has a
Pectin is a complicated branched structure of acidic structural polysaccharides, established in fruits and bast fibers. Most of the structure consists of homopolymeric partially methylated poly-α-(1-4)-D-galacturonic acid residues, but there are substantial 'hairy' non-gelling areas of alternating α-(1-2)-L-rhamnosyl-α-(1-4)-Dgalacturonosyl sections containing branch-points with mostly neutral side chains (1-20 residues) of mainly L-arabinose and D-galactose (rhamnogalacturonan-I). Pectin is the
Lab Report: Creating Bouncy Balls Tarannum Rahnuma Science10AP Purpose: The purpose of this experiment is to create a bouncy ball that bounces as high as possible. Problem: How does the quantity of specific ingredients in a bouncy ball recipe affect a ball’s bounciness? Background Research: Molecules that are made of recurring chemical units are called polymers. The glue used in this experiment to create bouncy balls contains the polymer polyvinyl acetate (PVA). When this is reacted
been a challenge in the history of adhesive dentistry. Currently, bond durability is one of the main research topics in adhesive dentistry. Regardless of the improvements in bonding technology, resin dentin bonds show limited durability for both etch and rinse and self-etch adhesive systems. The main problem concerning the durability of resin-dentin is the hydrolytic degradation of the two components of the hybrid layer. These are the collagen matrix and the adhesive resin [8]. Many approaches to enhance
From the time Buenocore first discovered adhesive dentistry in 1955, there has been continuous development in this field. This innovation has revolutionized restorative dental practice. Today’s direct composite restorations have a number of advantages over other restorative materials. ‘They are aesthetic, timesaving, minimally invasive and biologically compatible. Moreover, they are easy to handle, manipulate, repair and control’ (Dentistry today, 2008). Such mode of treatment not only involves a
volatile organic compounds, there is a demand to develop fast setting solvent free resins. Light cured materials have many advantages over conventional chemically cured adhesives, including consistent handling characteristics, single paste application, and easy removal of excess material and extended working time.1 UV-curable adhesives appear to be ideal candidates since such liquid formulations contain no organic solvents and are readily transformed into solids by a short exposure to UV-radiation at
Structural adhesives are used in a variety of applications such as automotive, durable goods, and building and construction. Adhesive chemistries can encompass one and two component polyurethane (PU), epoxy or cyanoacrylate, but in this article, we will discuss about the usage of polyurethane as the structural adhesive in automobile industry. Polyurethanes are made by the exothermic reactions between alcohols with two or more reactive hydroxyl (-OH) groups per molecule (diols, triols, polyols) and
An Auto shop Miracle: Scotch Tape The 1920s, an era commonly known as the “Roaring Twenties” was a time period filled with various new and innovative inventions. Starting off as a simple fix to a common problem, scotch tape was introduced in 1925 by a humble engineer, Richard Drew. Almost a century has passed since Richard Drew’s invention of scotch tape, and it is still used for various uses. The inventor, Richard Drew, grew up in St. Paul, Minnesota. After dropping out of college, he
The Correct Packaging Materials To Use When Shipping A Package When you are preparing to package items it is important to use the proper packaging materials. There are different materials for various items. If you are shipping a package through the mail it requires different supplies than packaging items to move yourself. Heavy items require extra attention as does fragile items. There are two basic types of packing materials, either plastic or paper. Both have several categories and should
When preparing to bandage a wound, always choose the proper bandage type for the wound or surface that will be bandaged. Make certain that the bandage is wide enough to cover the surface area. Always sanitize your hand prior to applying the bandage. I will tell you how to apply a bandage to the right arm. When applying the circular bandage, use your left hand to hold the bandage in place at the starting point and wrap from left to right around the site in a circular motion. Keep the bandage close
Going to the doctor seems so mundane yet necessary when we need a routine check-up or have an unknown sickness. As patients, we have never looked into how or why we visit the doctor but it is just something that we need to do when a problem arises. In the realm of medical visits, the doctor’s office holds great importance for the patient and doctors symbolizing a significant relationship between two people. In the video clip, “sore shoulder”, a woman visits the doctor for her concern of symptoms
I am going to share an incredible breathtaking day in my life. Earlier this year I attended Lady Gaga’s sold out show, The Joanne World Tour in Edmonton on August 3rd It was her second show after it kicked off in Vancouver. Me and and my best friend Kylie woke up at 4:45am to get ready. We showered, put on makeup and got our outfits ready. My outfit was made a week prior to the show. A leather jacket hot glued with diamonds, jewels and rhinestones with a red cross painted in the middle on the back
Ever since I was little I have always been interested in how things work, and I have always thought about how I could build them work better. As an example, I lived in Japan for two years while I was in first and second grade. I went to a small public school and loved to ski with my friends, we probably went skiing at least once a week during the winter. When I was skiing I would always be fascinated by the ski lifts and spend a good deal of time staring at them to try and figure out how they
How to Make Black Powder (and other explosives) Introduction Black Powder, also known as Gunpowder, is an explosive that has been around, literally, for centuries. The exact origins of the formula are lost in time, but it is known that the Chinese used Black Powder in weaponry at least 1,000 years ago. Technically, Black Powder burns by a process known as deflagration. This differs from detonation in that Black Powder produces subsonic shock waves, as opposed to the supersonic shock waves produced
