Water Resistance Straight dynamite has good water resistance. Gelatin dynamite is nearly waterproof. Ammonia dynamite has poor water resistance. Poor water resistance Good to excellent water resistance. Excellent water resistance. Fumes Straight dynamite has some toxic fumes. Ammonia and gelatin dynamite fumes are less toxic. ANFO produces less toxic fumes than dynamite but more than slurry or emulsion explosives. Slurries and emulsions have a similar fume class.
The least expensive and most available explosive. Widely available. Less expensive than dynamite, more expensive than ANFO. Similar in both cost and availability to slurries. Emulsion Explosives Emulsions are a water-in-oil type of explosive consisting of microdroplets of super-saturated oxidizer solution within an oil matrix.
Innovation Exchange Webinars This webinar series advances peer to peer conversations for launching change to encourage innovative problem solving in transportation. Most often used in smaller boreholes. Straight dynamite contains nitroglycerine, sodium nitrate, and a combustible absorbent e. Ammonia and gelatin dynamites are less volatile and sensitive to shock and friction than straight dynamite. Nobel died in , leaving his considerable estate as an endowment for annual awards in chemistry, physics, medicine or physiology, literature, and peace—all of which represented his lifelong interests.

When modeling these processes, it is difficult to A special type of infrared laser, known as a swept-wavelength external cavity quantum The new detection method is able to analyze a wider range of materials than current These give hints to scientists about the conditions under which diamonds are formed deep in the Earth's mantle. Despite having been known since , the explosive jump has not been fully Have We Detected Dark Energy?
Scientists Say It's a Possibility. Did you hear that explosion? It sounded like a thousand sticks of dynamite blowing up at once. Can you imagine what that might look and sound like?
If you're a fan of cartoons, you may have seen Wile E. Coyote and Roadrunner playing with dynamite from time to time. Isn't it amazing how they never seem to get hurt? Of course, unlike in cartoons, real dynamite is a powerful explosive that can be very damaging. Dynamite was invented in by Alfred Nobel. If you're wondering, yes, it's the same Alfred Nobel who started and funded the Nobel Prizes for scientific and cultural achievements.
His invention of dynamite made him very wealthy, which allowed him to fund what have become some of the most prestigious awards in the world. Before dynamite , the strongest explosive was gunpowder. Unfortunately, it wasn't strong enough for many needs and it also was dangerous to handle. Dynamite solved these problems by being both much stronger and much safer to handle. Dynamite was used then — and still is today — in the construction , mining, quarrying and demolition industries.
It also was used initially as a military weapon, although other weapons soon made dynamite obsolete. Nobel didn't really invent a new explosive when he developed dynamite. The explosive in dynamite — nitroglycerin — already existed.
The problem with nitroglycerin , though, is that it's very unstable and very dangerous to handle. Nobel's invention made the nitroglycerin safer to handle.
He did this by soaking it into a soft, chalky stone called diatomaceous earth. Today, diatomaceous earth is also often used to make cat litter. When soaked in diatomaceous earth , the nitroglycerin was much harder to set off and thus safer to handle.
Later on, other substances, such as sawdust and cellulose , were often substituted for diatomaceous earth. Dynamite is formed into explosive sticks that feature a wick and a blasting cap. The wick is lit, which leads to a small explosion when it reaches the blasting cap. When the blasting cap explodes, the nitroglycerin then causes a much larger explosion.
Some people believe the burning wick actually sets off the nitroglycerin. In reality, a stick of dynamite can be burned without exploding. It's the small explosion of the blasting cap that is required to cause the nitroglycerin to explode. TNT stands for trinitrotoluene , which is also an explosive but quite different from dynamite. Dynamite is actually much more powerful than TNT. Did you think today's Wonder of the Day was dynamite? We hope so! Grab a friend or family member and try one or more of the activities below.
They're sure to blow your mind! The question was 'How does Dynamite Work? Dynamite has a chemical reaction--which makes it perfect for study in a science classroom via video, of course!
