How do pop rocks work?

Here's the basic idea. Hard candy (like a lollypop or a Jolly Rancher) is made from sugar, corn syrup, water and flavoring. You heat the ingredients together and boil the mixture to drive off all of the water. Then you let the temperature rise. What you are left with is a pure sugar syrup at about 300 degrees F (150 degrees C). When it cools, you have hard candy. \n\nTo make Pop Rocks, the hot sugar mixture is allowed to mix with carbon dioxide gas at about 600 pounds per square inch (psi). The carbon dioxide gas forms tiny, 600-psi bubbles in the candy. Once it cools, you release the pressure and the candy shatters, but the pieces still contain the high-pressure bubbles (look at a piece with a magnifying glass to see the bubbles). \n\nWhen you put the candy in your mouth, it melts (just like hard candy) and releases the bubbles with a loud POP! What you are hearing and feeling is the 600-psi carbon dioxide gas being released from each bubble.

Sedimentary rocks can be divided into two major informal groups, referred to as clastics (or siliciclastics) and carbonates. Clastic rocks are formed by erosion of other rocks, igneous, metamorphic and sedimentary. These 'clasts' can be mud, silt, sand, cobbles, or boulders, and are transported by wind, water, or gravity and accumulate where they eventually are buried and pressure and temperature subject them to diagenesis, the process that makes them from unconsolidated clasts to one rock mass. Shale, sandstone, and conglomerate are examples of clastics.\n\nCarbonates can work much differently since they form primarily in the oceans. Many carbonates are made from reefs and other living organisms that grow in the ocean. As these organisms die and leave behind their carbonate skeletons, rocks are formed. Other carbonates are formed from small grains called ooids, small balls that form by precipitating out of sea water, possibly with the help of bacteria or algae. Some ocean algae even form carbonate 'mud' that eventually becomes hard rock. \n\nAnother unusual group of sedimentary rocks are called evaporites. These are rocks like gypsum and rock salt that are deposited by evaporation of water in confined basins. \n\nThe most fascinating part about sedimentary rocks is that they have a past, each one tells a story.

In order to crack stone bricks loose.\n\nThey first carved the desired shape into large stones at a quarry, then they firmly inserted DRY wooden wedges inside the carvings. Then they soaked it in water.\n\nThis caused the wedges to expand as it absorbed water and it broke the stones loose.

Igneous, metamorphic, and sedimentary rocks all have the potential to become one of each of the other types of rock through the rock cycle. Igneous and metamorphic rocks can be broken down into rock fragments and cemented to form a sedimentary rock. Sedimentary or igneous rocks can undergo changes in temperature and pressure to form metamorphic rocks. And all three types can be melted and reformed as igneous rocks.

the simplest explanation is as follows:\n\n* igneous rocks are formed when molten lava is erupted on to the earth's surface and cools. i.e. basalt lavas. \n\n* sedimentary rocks are formed when other rocks (possibly igneous, metamorphic or previous sediemtnary rocks) are eroded chemically or physically and are then redeposited. i.e. sandstones and mud stones.\n\n* metamorphic rocks are formed when other rocks (igneous or sedimentary typically) are buried and then exposed to high temperatures and pressures that change the properties of that rock. i.e. marble - metamorphosed limestone.

rock refers to solid mineral deposits. Rocks are minerals, but not all minerals are rocks.\nSome minerals, given time and circumstance, form solid deposits. These solid mineral deposits are known as rock. Pressure, temperature, erosion, and friction are forces that effect the formation of rocks. The rock formation process allows geologists to classify rocks into three groups: sedimentary, igneous, and metamorphic. Sedimentary rock forms when layers of "sediment" (small particles of solid minerals like sand and pebbles) fuse together over time under the force of water or wind. Sedimentary rock is commonly found in and near riverbeds and streambeds. Igneous ("fire-formed") rock forms after minerals are heated to extremely high temperatures and then allowed to cool.

Igneous rocks are formed with heat. They are most commonly found around volcanoes. Metamorphic rocks are formed with heat and pressure. Sedimentary rocks, like sandstone and limestone, are formed by pressure.

Sedimentary rock forms relatively flat. Youngest always on top of the oldest. Just like a stack of newspapers if you were to accumulate them everyday.\n\nFolding from compressional stress is one. Rock is literally pushed together creating anticlines & synclines, upward folding & downward folding arches respectively.\n\nFaults can also do this. This can be accomplished through compressional (pushed together) or tensional (pulled apart) stresses.\n\nI am not too sure about this one but isostatic adjustment could possibly tilt rocks.\n\nHope this helps.\n\n:)

its pretty simple and self-explanitorie.  you get cranberies, or berries off a tree, and pop a big bowl of popcorn.  you take a needle and a loooooooong piece of thread and basically piece eah thing onto the string.  to stop the ends, put hot glue there.  its really simple and cute.  good luck!

A clastic rock is a sedimentary rock formed of particles deposited by water, wind, ice, gravity.  The particles themselves would give the rock texture--think of the gritty surface of a sandtone. Detrital texture is described by size, shape, and composition or the sorting of the redeposited particles. \n\nA chemical sedimentary rock is formed by precipitating from water solution. They precipate "in place", and are not formed by redeposited particles like clastic rocks. These include evaporites, opal, some carbonates, iron oxides, etc. Stalactites are examples. Dried up lake beds form flat layers of evaporites, another example. Chemical textures are usually crystalline with some special descriptions like pisolitic or  oolitic.\n\nThe category not mentioned is that of biological sedimentary rocks--composed largely of plant or animal material.

The simple way is to make a solor still. Dig a hole, fill with some salt water.  Take some plastic (big enough to cover hole) Weigh it down around the edges so that it wouldn't move or blow away leave a hint of slack in it.  Put a smal rock in the middle.  Put a can/cup ect under the rock. As the water evaporates it will collect on the plastic, on drip from where the rock is.  Drips fall in cup.  Fresh water.  You can boil sea water and cool steam, collect drips in bucket.

Mmmm... Salt....\n\nYou will get a super-saturated solution. Like the sugar they use to make rock candy, salt dissolves better in hot water. Saturated means it has as much solute (salt, in your question) in it as will possibly dissolve, so a saturated solution at 60 degrees celsius has quite a lot of salt in it!\n\nAs the saturated solution goes back to normal temperatures, it eventually reaches the point where there is MORE salt in solution than would normally dissolve. This is called a super-saturated solution. It still looks like it did before, except saltier than normally possible.\n\nSeveral things can happen to a super-saturated solution as it cools. Either it appears unchanged, or crystals start to grow like when you are making rock candy. You would see crystals around the edges and on the sides and bottom of the container. Some substances like sodium nitrate are so soluable that they can crystalize all at once when disturbed, which looks like the solution instantly froze solid. Table salt does not normally do this, so just write that it would go from saturated to super-saturated and crystals would form.

Saliva works by breaking down foods with enzymes that prepare it for entry into the digestive tract and entry into the stomach. I think that's what you meant. Unless you mean - \nThey are in a band. They play live gigs and sell CDs that sell millions. Unless you mean - \nIt works by humiliating the person you spit on. \nMothers use it to rub anything off your face. \nPeople use it to make a envelope sticky.

Noise is created with the movement of particles.  The popping noise is caused by the air particles inside the balloon very rapidly moving outside the balloon.

It depends.  Wood floats on water, as does ice.  Rocks sink.

Rocks tell the story of the Earth. The Earth is made of rock, from the tallest mountains to the floor of the deepest ocean. Thousands of different types of rocks and minerals have been found on Earth. Most rocks at the Earth's surface are formed from only eight elements (oxygen, silicon, aluminum, iron, magnesium, calcium, potassium, and sodium), but these elements are combined in a number of ways to make rocks that are very different.\nRocks are continually changing. Wind and water wear them down and carry bits of rock away; the tiny particles accumulate in a lake or ocean and harden into rock again. The oldest rock that has ever been found is more than 3.9 billion years old. The Earth itself is at least 4.5 billion years old, but rocks from the beginning of Earth's history have changed so much from their original form that they have become new kinds of rock. By studying how rocks form and change, scientists have built a solid understanding of the Earth we live on and its long history.
