Strontium and lithium are two elements whose compounds burn with a red flame and are commonly used in fireworks and signal flares. The strontium compound strontium nitrate and the lithium compound lithium carbonate are examples of substances that contribute to the red color in pyrotechnics.

Fireworks were made sometime in the years 800s

Yes, fireworks can hurt a dog's ears due to their sensitive hearing. The loud noise can cause stress, anxiety, and potentially permanent damage to their hearing. It's important to take precautions to protect your dog during fireworks displays, such as keeping them indoors in a safe, quiet space.

Yes, Knott's Berry Farm occasionally host special events with parades and fireworks, such as during the holiday season. It's best to check their website or social media for updates on their event calendar.

Fireworks have nowhere near enough fuel to send them into earth orbit. In fact, to do so would defeat the whole purpose of the piece, since it is built specifically to cause a lavish and colorful aerial display and to be seen by observers on the ground.

So, once its fuel is spent, there is no longer any upward force on the piece to cancel the downward force of gravity, and its motion is no different from that of a stone released at the same altitude above ground.

You are supposed to lay down near the Pikmin, and the Pikmin will carry you to their Onion and you will be lifted up into it (you will not go into the onion) and you fall back down then on top of the onion you will see fireworks. This only works if you obtain the item that allows you to lay down. There are no harmful or meaningful effects of the fireworks.

Yes. Fourth Officer Joseph G. Boxhall and Quartermaster Alfred Rowe were ordered by Smith to fire distress rockets. These were rockets which burst in a white cluster high enough above the ship to be seen from at least 10-15 miles away or more under favorable conditions. Between 12:45 AM and about 1:45 AM on April 15, 1912, 8 rockets were fired from the sinking Titanic. The only ship that was definitely close enough to see them was the Leyland steamer Californian, whose master, Stanley Lord, inexplicably failed to wake his wireless operator to see if a vessel was in distress. Californian's officers on watch saw all 8 being fired and were only ordered by Lord to try to contact the ship via Morse lamp.

Fireworks can appear yellow due to the presence of certain chemical compounds in the pyrotechnic composition, such as sodium compounds. When ignited, these compounds release energy in the form of light, with the emission spectra often resulting in yellow hues. The specific color of the firework depends on the chemical composition and the temperature at which the compounds burn.

Generally, they (meaning pyrotechnics) use salts to create colors (and a variety at that, because they come in different colors). For example, strontium salts are used to create red, and blue is created using copper compounds.

Are you SERIOUS?!

Cause they might blow up and your house will be blown up, and there might be humans in there?

In houses there's electricity which can ignite the explosives and it's way more dangerous if the stuff blows up indoors, since you have a roof that will be collapsing on you. Outsides there's just - space?

Just DON'T keep it - don't even have it. Or blow it up right away, controlled.

; D Yer sorri,, it was a question I had in my coursework and I wasnt sure reli wat to put, I wanted it to sound grown up!!!!!!!!!!!!!!!

Gunpowder is placed throughout packaging and shot off into the sky. Its explosion relies on the right level of heat from a lit fuse. Other elements such as charcoal are added to produce various colors.

Fireworks are important for cultural and entertainment purposes, adding color and excitement to celebrations and events around the world. They also have significance in religious and traditional ceremonies, contributing to the cultural heritage of different societies. Additionally, fireworks serve as a form of artistic expression and bring people together to enjoy communal experiences.

I am not 100% percent positive but I believe it is because any other fabric will burn and melt or fuse to the skin, cotton burns off clean. Also I believe it is special in that it has anti-static properties.

It is to prevent the possibility of sparks caused by the build up of static electricity.

The magic wand tool in Macromedia Fireworks is used to select areas of an image that share similar colors or tones. It allows you to quickly select and edit specific parts of an image based on its color properties. It's helpful for tasks like creating masks, selecting objects, or making adjustments to specific areas of an image.

The yellow non-metal is sulfur. It is commonly found in hot water springs and volcanoes. Sulfur emissions contribute to acid rain, and it is used in matches, fireworks, and various medicines due to its diverse chemical properties.

Fireworks were invented in ancient China, and the 7th century Chinese alchemist Li Tian is often credited with their discovery. The early fireworks were likely created by accident while trying to come up with a concoction for immortality. Today, fireworks are used for celebrations and events all over the world.

Fireworks were invented in China over 2,000 years ago. It is believed that they were accidentally discovered by a Chinese cook who mixed sulfur, charcoal, and saltpeter (potassium nitrate) together and noticed the mixture exploded when heated. This discovery eventually led to the development of fireworks for celebrations and religious ceremonies.

A firework undergoes both physical and chemical changes. The lighting of the firework involves a chemical reaction within the firework's composition to produce the colors and effects seen in the sky. The transformation of the firework materials into smoke and ash after the display represents a physical change.

A Chinese monk named Li Tian invented fireworks about 1,000 years ago. The earliest recorded use of gunpowder in England, and probably the western world, is by the Franciscan monk Roger Bacon.

Legend has it that Marco Polo brought this new accidental invention to the West from one of his many trips to China and other Eastern countries
