Let's Crank Some Ice Cream
Let’s Crank Some Ice Cream! The history of ice harvesting, the ice industry, refrigeration, and making ice cream Kathi Elkins 7-29-19 OLLI: Summer 2019 Ice Storage and Ice Houses: 1780 BC --- ice house in northern Mesopotamian 1100 BC --- evidence of ice pits in China By 400 BC --- Persian engineers had mastered techniques of constructing yakhchāl to store ice harvested from nearby mountains. 300 BC --- Alexander the Great (snow pits to hold snow and ice) 200s AD --- Romans (snow shops) Cold springs, root cellars Ice Houses: Yakhchāl (this one at Yazd, Iran) is a Persian ice pit or a type of evaporative cooler. Above ground, the structure had a domed shape, but had a subterranean storage space. It was often used to store ice and food. The subterranean space coupled with the thick heat-resistant construction material insulated the storage space all year. Ice Houses: Ice houses in England/UK. Ice Houses: Croome's thatched ice house, Worcestershire, UK Ice Houses: Botany Bay Icehouse, Edisto Island, SC Ice Houses: Ice house designs usually began as an underground egg-shaped cellar. This ice house, dating from 1780s and designed by architect John Nash, was discovered in 2018 buried under London streets. In 1822, following a very mild winter, William Leftwich chartered a vessel to Norway to collect 300 tons of ice harvested from crystal-clear frozen lakes. Previous imports had been lost at sea, or melted while baffled customs officials dithered over how to tax such unique cargo. John Nash designed the Royal Pavilion at Brighton, as well as Buckingham Palace. -

They are often found in mountains, • 3 of your favorite kinds of cookies. but can be found in other places, too. Washington • 1/4 cup of light-colored was half covered in a syrup (butterscotch, glacier during the Ice Age! marshmallow, etc.) • Plastic sandwich bag or similar. Glacial till: Materials, such as rocks and dirt, left • A clear bowl. behind when a glacier • A spoon. melts. Most of the soil in the Seattle area is made of glacial till. Daisy at Home Recipe for a Small Glacier Instructions 1. Crumble up the cookies and put them in the bowl. This represents dirt and rocks that will become glacial till. 2. Put two big scoops of the ice cream on top of the crumbled cookies. Glaciers begin as clean snow and ice, but they pick up dirt and rocks from the ground as they travel. So, the ice cream with its swirls represents this “dirty” glacier! 3. Slide the plastic sandwich bag over your hand. Then, slowly push down or “smoosh” the ice cream so it oozes! What do you notice? What happens to the cookie crumbles? A glacier moves in a similar way. As more snow falls on it, the added weight causes the glacier to “ooze” or “flow,” pushing the dirt in all directions. 4. To see how glaciers flow, heat up your light-colored syrup and pour it over the ice cream. -
Gas Hydrates As a Functional Foaming Agent for Viscous Food Matrices

ETH No. 25820 Gas hydrates as a functional foaming agent for viscous food matrices A dissertation submitted to attain the degree of DOCTOR OF SCIENCES of ETH ZURICH (Dr. sc. ETH Zurich) presented by Zuzana Šedivá MSc in Food Science ETH Zurich born 26th May 1987 citizen of Czech Republic accepted on the recommendation of Prof. Dr. E. J. Windhab, Examiner Dr. Martin Leser, Co-Examiner Dr. Vincent Meunier, Co-Examiner 2019 Summary A novel technology for foaming viscous slurries was designed. The process involved a crystalline gas hydrate dispersion as a functional ingredient standing in the core of the technology. Gas hydrates, also known as clathrate hydrates, are solid inclusion compounds, in which gas molecules are physically entrapped in a network of cavities made up of water molecules held together by hydrogen bonds (Marinhas et al., 2007). Gas hydrates exist at moderate pressures and low temperatures and possess a high volumetric gas storage capacity. The innovative idea of replacing highly energetically demanding foaming of viscous slurries using pure gas with the gas hydrate technology emerges in the current study. Introducing a gas as a slurry in its solid clathrate form into another viscous product stream reduces the energy input otherwise needed in powerful mixing devices. -
A Field Guide to Falling Snow
Basic Snowflake Forms (from SnowCrystals.com) Although no two snowflakes are exactly alike, snow crystal forms usually fall into several broad categories. You can find a more descriptive guide in the book – The Snowflake: Winter’s Secret Beauty. Stellar Dendrites Dendrite means "tree-like", which describes the multi-branched appearance of these snow crystals. Stellar dendrites have six symmetrical main branches and a large number of randomly placed sidebranches. They can also be large, perhaps 5mm in diameter. Although they have complex shapes, each stellar dendrite is a single crystal of ice. The molecular ordering of the water molecules is the same from one side of the crystal to the other. Sectored Plates What identifies these crystals are the numerous ice ridges that seem to divide the plate-like arms into sectors -- hence the name. Like the stellar dendrites, sectored plates are flat, thin slivers of ice that grow into in a stunning diversity of complex shapes. Hollow Columns Plate-like snow crystals get the most attention, but columnar crystals are the main constituents of many snowfalls. The columns are hexagonal, like a wooden pencil, and they often form with conical hollow features in their ends. Needles Columnar crystals can grow so long and thin that they look like ice needles. Sometimes the needles contain thin hollow regions, and sometimes the ends split into additional needle branches. Spatial Dendrites Not all snowflakes form as thin flat plates or slender columns. Spatial dendrites are made from many individual ice crystals jumbled together. Each branch is like one arm of a stellar crystal, but the different branches are oriented randomly. -
ESSENTIALS of METEOROLOGY (7Th Ed.) GLOSSARY
ESSENTIALS OF METEOROLOGY (7th ed.) GLOSSARY Chapter 1 Aerosols Tiny suspended solid particles (dust, smoke, etc.) or liquid droplets that enter the atmosphere from either natural or human (anthropogenic) sources, such as the burning of fossil fuels. Sulfur-containing fossil fuels, such as coal, produce sulfate aerosols. Air density The ratio of the mass of a substance to the volume occupied by it. Air density is usually expressed as g/cm3 or kg/m3. Also See Density. Air pressure The pressure exerted by the mass of air above a given point, usually expressed in millibars (mb), inches of (atmospheric mercury (Hg) or in hectopascals (hPa). pressure) Atmosphere The envelope of gases that surround a planet and are held to it by the planet's gravitational attraction. The earth's atmosphere is mainly nitrogen and oxygen. Carbon dioxide (CO2) A colorless, odorless gas whose concentration is about 0.039 percent (390 ppm) in a volume of air near sea level. It is a selective absorber of infrared radiation and, consequently, it is important in the earth's atmospheric greenhouse effect. Solid CO2 is called dry ice. Climate The accumulation of daily and seasonal weather events over a long period of time. Front The transition zone between two distinct air masses. Hurricane A tropical cyclone having winds in excess of 64 knots (74 mi/hr). Ionosphere An electrified region of the upper atmosphere where fairly large concentrations of ions and free electrons exist. Lapse rate The rate at which an atmospheric variable (usually temperature) decreases with height. (See Environmental lapse rate.) Mesosphere The atmospheric layer between the stratosphere and the thermosphere. -
Science Lesson Plan
How Do Glaciers Scratch And Move Rocks? Purpose: Students will model the action of a rock-filled glacier with ice cubes and learn how glaciers can make scratches in Earths surface. Text: McGraw Hill, Pg. 175 Explore Activity McGraw Hill Science Journal, Pg. 75 Resources: I have added an additional experiment that you can do in your classroom after lab to reinforce the concepts being taught this week. Learning Outcomes: Students will discuss and know how glaciers scratch and move rocks. (Homeroom Teacher) Bridge-in: Share student’s hypothesis with class: How can a block of ice help shape the Earth’s surface? Prior Knowledge: How are icebergs formed? Do you think that a glacier is able to make scratches in the Earth’s surface? If YES, then HOW? If NO, then WHY? Input from you: Review what a prediction is. What is meant by using, the word, variable(s) in an experiment? What is an observation? What do I mean when I use the term inference? (Science Facilitator) Materials: Science Notebook Science Journal Pg. 75 Paper towels Clean ice cubes Ice cubes made with sand Aluminum foil Wood scraps, large enough to scrape ice cubes against. Guided Procedure: Predict: Which ice cube do you think is more like a real glacier? Record your prediction and reasons in your journal. Using Variables: Think about how you could use the materials to test your ideas. Which ice cube will scratch a surface? Record your observations for each ice cube. Observation: Which cube will leave “rocks” behind? Place the ice cubes on a folded paper towel. -
Properties of Diamond Dust Type Ice Crystals Observed in Summer Season at Amundsen-Scott South Pole Station, Antarctica
180 JournaloftheMeteorological SocietyofJapanVol 57,No.2 Properties of Diamond Dust Type Ice Crystals Observed in Summer Season at Amundsen-Scott South Pole Station, Antarctica By Katsuhiro Kikuchi Department of Geophysics, Hokkaido University, Sapporo and Austin W. Hogan Atmospheric Sciences Research Center, State University of New York at Albany, Albany, New York (Manuscript received 17 November 1977, in revised form 20 May 1978) Abstract The properties of diamond dust type ice crystals were studied from replicas obtained during the 1975 austral summer at South Pole Station, Antarctica. The time variation of the number concentration and shapes of crystals, and the length of the c-axis, the axial ratio (c/a) and the growth mode of columnar type crystal were examined at an air tempera- ture of -35*. Columnar type crystals prevailed, but occasionally more than half the number of ice crystals were plate types, including hexagonal, scalene hexagonal, pentagonal, rhombic, trapezoidal and triangular plates. A time variation of two hour periodicity was found in the number concentration of columnar and plate type crystals. When the number con- centration of columnar type crystals decreased, the length of the c-axis of columnar type crystals also decreased. When the number concentration of columnar type crystals increased, the length of the c-axis of the crystals also increased. There was sufficient water vapor to grow these ice crystals in a supersaturation layer several tens to several hundred meters above the surface. The growth mode of columnar type crystals was different from that of warm and cold region columns reported by Ono (1969). The mass growth rate was 6.0* 10-10 gr*sec-1, and was similar to that obtained in cold room experiments by Mason (1953), but less than that found in field experiments by Isono, et al. -
RECIPE for MAKING LIQUID NITROGEN ICE CREAM (Serves About 18-20 Students)
RECIPE FOR MAKING LIQUID NITROGEN ICE CREAM (serves about 18-20 students) NOTE: This is NOT a regular ChemDemo activity but rather a “treat” to go along with a regular ChemDemo 1. Add 1 quart Half and Half and 1 quart Heavy Whipping Cream into a large plastic or glass salad or punch bowl. 2. Add ¾ to 1 cup of granulated sugar (1 cup is a little on the sweet side). 3. 4-5 teaspoons of vanilla. 4. Optional: 1 pound of fresh fruit or preserves (not jelly). Strawberry or peach works best. If using fresh fruit, cut into small pieces. Chocolate syrup (8 oz) works well to make chocolate ice cream. If using chocolate syrup use less sugar (½ to ¾ cup). 5. Stir the mix for 2-3 minutes to dissolve the sugar. 6. Add about 2-3 liters of liquid nitrogen slowly and in small portions into the mix and stir with a wooden spoon. Pour a little at a time and stir; then continue adding small amounts of liquid nitrogen until you have the desired consistency. One person should be stirring while another gradually pours in the LN2. Another person may be necessary to hold the container when it starts getting thick. 7. Allow any excess liquid nitrogen to boil off. 8. Serve to your audience. Enough for 20 students (half a cup each). 9. Wash equipment and enjoy. SAFETY NOTE: LN2 is extremely cold (-196°C, -321°F, 77 K)!! Spilling it on you can cause serious frost- bite burns! Pouring some on unprotected skin is actually less dangerous than on clothing in contact with skin.
