The odd chemical reaction between Coke and milk. Audi have successfully made diesel fuel from carbon dioxide and water. German car manufacturer Audi has reportedly invented a carbon-neutral diesel fuel, made solely from water, carbon dioxide and renewable energy sources.

Audi have successfully made diesel fuel from carbon dioxide and water

And the crystal clear 'e-diesel' is already being used to power the Audi A8 owned by the country’s Federal Minister of Education and Research, Johanna Wanka. The creation of the fuel is a huge step forward for sustainable transport, but the fact that it’s being backed by an automotive giant is even more exciting. Audi has now set up a pilot plant in Dresden, Germany, operated by clean tech company Sunfire, which will pump out 160 litres of the synthetic diesel every day in the coming months.

Their base product, which they’re calling 'blue crude' is created using a three-step process. The first step involves harvesting renewable energy from sources such as wind, solar and hydropower. This hydrogen is then mixed with carbon monoxide (CO), which is created from carbon dioxide (CO2) that’s been harvested from the atmosphere. The hypnotic recrystallisation of 4-hydroxybenzaldehyde. Marvel in awe at the swirly, hypnotic recrystallisation of 4-hydroxybenzaldehyde.

The magical effect above is triggered when a flask of the reddish solution is dunked into an ice bath, and the chemistry going on behind the scenes is pretty damn cool. As you can see in the video above, which was uploaded by scientist Christopher Lyon, the solution starts to become taken over by a white, smoky solid as it cools down.

Melting Metal With Magnets The Science: The copper wire has a significant amount of AC electricity running through it, causing it to act like a really strong electromagnet. Apparently, Burning NH4Cr2O7 With HgSCN Opens A Portal To Hell. Of all the chemical reactions we've covered within the past few months, the one filmed below probaby takes the prize for coolest looking and possibly scariest.

Apparently, Burning NH4Cr2O7 With HgSCN Opens A Portal To Hell.

After the pile of reactants is lit, it begins to look like tentacles are crawling out of a portal to Hell. In reality, what's depicted in the video below is actually two reactions: the decomposition of ammonium dichromate and the combustion reaction of mercury (II) thiocyanate. The orange powder is ammonium dichromate and when heat is introduced, it forms nitrogen gas, water, and ammonium (III) oxide, which is the dark powder that looks like the volcano you see. What appears to be tentacles is actually what happens when heat is introduced to mercury (II) thiocyanate. The white solid expands when it's heated to become a dark, tentacle-like mass due to its decomposition to carbon nitride.

WATCH: Lead iodide forms 'golden snow'

[optional caption text here] Image: [name here]/Shutterstock This pretty result is caused by an instantaneous chemical reaction set off by mixing solutions of potassium iodide and lead nitrate. Here’s how the experiment is carried out, according to the creator of the video, Thoisoi2, on YouTube. You need to start off by preparing two separate colourless solutions of potassium iodide and lead nitrate mixed with hot distilled water.

Combine the two solutions in a large beaker and they should turn a bright yellow colour. Over time, as the solution gradually cools down, the lead iodide precipitate will appear again as pretty golden flakes. ScienceAlert - Timeline Photos. Empirical evidence that humans are causing global warming. The proof that man-made CO2 is causing global warming is like the chain of evidence in a court case.
