What is Fire
What fire is, using a candle flame as an example. This starts with the fact that the wax in a candle is made up of long hydrocarbon molecules that when heated, by a match for example, break up into carbon and hydrogen atoms and start moving around randomly in the form of a gas. This is called pyrolysis. They then collide with oxygen atoms in the air and give off bluish light in a process called chemiluminescence. They bond with those oxygen atoms and give off heat, adding more heat to keep the process going. This is called oxidation. Some of the newly created molecules are water and carbon dioxide. In fires where there are leftover carbon atoms, such as candle fires, those atoms may clump together to form soot. This soot heats up and glows, giving the flame it's yellowish, orangish and/or reddish color, depending on the temperature.

Time Travel and 4D Spacetime - Flame Challenge 2013 Finalist
This video about space-time, relativity and time travel was submitted to the Flame Challenge 2013, whose goal was to give an answer to the question What Is Time? that an 11-year old could understand. Tens of thousands of grade 5 students from all over the world rated the submitted entries, and my video made the short list of finalists:
Ella Mae sings An American Trilogy by Elvis Presley
20 months old and she's a big fan of Elvis and her Daddy!
We had the great pleasure of meeting Lisa Marie Presley at her concert last week. She was so nice and hung out with Ella before the show. It was an amazing experience for the whole family!
For those of you wanting to see more Ella, I've uploaded pictures of the event and various other pictures here.
Thank you everyone for all the kind words about Ella Mae! We really appreciate all of the likes and shares!!! She really is a lot of fun as you can see.
To answer the big question, Yes Ella does like to sing other songs. Some of her favorites include, of course more Elvis - Suspicious Minds & Lawdy Miss Clawdy; The Beatles - Twist & Shout; Stray Cats - Stray Cat Strut; JD McPherson - Fire Bug; The Beach Boys - Barbra Ann; Bruno Mars - The Lazy Song; Bobby Day - Rockin' Robin and Richard Marx - Right Here Waiting For You (duet with Mom!!!). However she is only 21 months old and easily distracted so it can be quite challenging to get another video like this one. If we can come up with another good one I will definitely post it.
For all of the comments about the straps on the car seat, we adjusted them shortly after posting this video. They now sit below her shoulders. Thanks for the advice!
Thanks again for all of the positive feedback!

What is fire? - James May Q&A; - Head Squeeze
Discover the scientific nature of fire with James May in this Head squeeze video Q&A.;
Fire, pretty essential really and something we often take for granted, but what exactly is it? Well to create fire you need three things - some fuel, a heat source and oxygen. If we remove any one of these, then the fire will go out. When we apply sufficient heat to the fuel for it to reach its ignition point, the material will combust in the presence of oxygen.
Combustion is actually the process by which the fuel decomposes, its molecules breaking down, releasing and recombining with the oxygen to produce water, carbon dioxide, carbon monoxide and all sorts of other things.
The flames which we see are composed of incandescent soot, this is not fire, as ethanol for example, can produce fire without visible flames. Incandescence increases with temperature and so we can estimate the heat of the flames moving from red, through orange, to the hottest of all - white heat.
There's much more to fire than this and James May explains all in this fantastic head squeeze video. If you enjoyed it as much as we did subscribe for more, like, share and give us your thoughts in the lively comments below.

The Science of Fire
Richard Feynman describes the chemical chain reaction that we call fire.
The Original Double Slit Experiment
Light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles?
The experiment was conducted by Thomas Young and is known as Young's Double Slit Experiment. This famous experiment is actually a simplification of a series of experiments on light conducted by Young. In a completely darkened room, Young allowed a thin beam of sunlight to pass through an aperture on his window and onto two narrow, closely spaced openings (the double slit). This sunlight then cast a shadow onto the wall behind the apparatus. Young found that the light diffracted as it passed through the slits, and then interfered with itself, created a series of light and dark spots. Since the sunlight consists of all colours of the rainbow, these colours were also visible in the projected spots. Young concluded that light consist of waves and not particles since only waves were known to diffract and interfere in exactly the manner that light did in his experiment.
The way I have always seen this experiment performed is with a laser and a manufactured double slit but since the experiment was conducted in 1801 I have always thought that it should be possible to recreate the experiment using sunlight and household materials. That is basically what I did here. I will show the interference pattern I observed with my homemade double slit on 2Veritasium but I chose to use a manufactured double slit here to ensure that the pattern was impressive for observers at the beach.
Special thanks to Henry, Brady, and Rupert for their cameos, Glen for filming and Josh for helping create the apparatus. Thanks also to the Royal Society for allowing us to view the original manuscript of Young's lecture and the University of Sydney for lending the double slits.

What is The Flame Challenge?
Since he was 11 years old, Alan Alda has asked questions about flames. But for a long time, the answers eluded him. As he learned at a young age, procuring information from the notoriously insular scientific community is often difficult. Generally, they’re not the best communicators, he said, particularly when it comes to discussing their fields of expertise. But could that change?
At the World Science Festival program, “Alan Alda’s Burning Question: What Is A Flame?,” the actor and noted science enthusiast acknowledged that unpacking complex scientific ideas to a lay person is “very hard to do” but certainly not impossible. As he addressed roughly 200 audience members gathered at the Bennack Theater at the Paley Center for Media, Alda said that teaching scientists to explain theories and voice their work clearly is vital for breaking through public resistance to new ideas and beliefs.
The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

What Is a Flame?
A brief animated explanation of fire.
produced by Mara Grunbaum ( and Ferris Jabr (
music: DJ Rkod
an entry in the 2012 Flame Challenge:
Chemistry experiment 46 - Flaming Flask
Aluminium by itself is a very reactive metal. However, aluminium is oxidized when exposed to air, forming a thin layer of protective aluminium oxide on its surface.
When some aluminium foil is added to a solution of copper(II) chloride in concentrated hydrochloric acid, the layer of aluminium oxide will be destroyed by chloride ions.
Al2O3 + 2Cl- + 3H2O → 2[Al(OH)2Cl] + 2OH-
The exposed aluminium metal reacts with hydrochloric acid, producing hydrogen gas.
2Al + 6H3O+ → 2Al3+ + 6H2O + 3H2
Hydrogen gas can be ignited.
The color of the flame is blue/green due to the presence of Cu2+ ions.
- Hydrochloric acid is very corrosive

Magnetism seems like a pretty magical phenomenon. Rocks that attract or repel each other at a distance - that's really cool - and electric current in a wire interacts in the same way. What's even more amazing is how it works. We normally think of special relativity as having little bearing on our lives because everything happens at such low speeds that relativistic effects are negligible. But when you consider the large number of charges in a wire and the strength of the electric interaction, you can see that electromagnets function thanks to the special relativistic effect of length contraction. In a frame of reference moving with the charges, there is an electric field that creates a force on the charges. But in the lab frame, there is no electric field so it must be a magnetic field creating the force. Hence we see that a magnetic field is what an electric field becomes when an electrically charged object starts moving.
I was inspired to make this video by Prof. Eric Mazur
Huge thank you to Ralph at the School of Physics, University of Sydney for helping us out with all this magnetic gear. Thanks also to geology for loaning the rocks.
This video was filmed in the studio at the University of New South Wales - thanks to all the staff there for their time and support.
