What household items can you use to make fake smoke?
Mix one part glycerin with three parts distilled water. You don’t need a lot for a bunch of fog. Start with a small glass and work up from there, if you need for more. At first, the mixture will appear cloudy.
Does smoke mean fire?
Smoke is the biproduct of the fuels it is burning. The color of the smoke indicates to firefighters the type and density of the fuels involved, all of which gives hints as to what the fire might do next. White smoke can also indicate light and flashy fuels such as grass or twigs.
What is hotter blue fire or lava?
While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava. Red lava is colder than candle flames.
Is blue or purple fire hotter?
As things heat up and combustion becomes more complete, flames turn from red to orange, yellow and blue. And purple color is combination of red & blue color it means that blue fire is more hotter than purple fire. At hotter temperatures, the flame color moves into the blue-violet end of the visible spectrum.
What color is a dying star?
white
Does a star ever die?
Despite being so much heavier than their red dwarf cousins, these stars have much shorter life spans: Within only a few million years (which given astronomical time scales might as well be next week) they die. But when massive stars die, they go out in all their glory.
Do Dead stars still shine?
After a star dies, there is still some residual heat left over. That heat makes the star (white dwarf or neutron star) glow, even though it is not producing any energy. Eventually, the star cools off and does indeed simply become a hunk of ash, which we call a “black dwarf.”
What will happen if a star explodes?
A supernova can shine as brightly as an entire galaxy of billions of “normal” stars. Some of these explosions completely destroy the star, while others leave behind either a super-dense neutron star or a black hole — an object with such powerful gravity that not even light can escape from it.
Can a star explode?
Such stars explode when they use up their nuclear fuel and collapse. Stars weighing more than about eight times the Sun’s mass burn through their hydrogen fuel quickly, but as a massive star runs low on one fuel, it taps into another. Each new fuel releases less energy, so the star burns through it even faster.
How does a star die?
Stars die because they exhaust their nuclear fuel. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’.
How long does it take a star to collapse?
So, how long does a supernova take to explode? A few million years for the star to die, less than a quarter of a second for its core to collapse, a few hours for the shockwave to reach the surface of the star, a few months to brighten, and then just few years to fade away.
