- cafman, on 10/26/2008, -0/+14Great Photos, a bit more detail about the content of the photos would be really cool.
- dicketj8050, on 10/26/2008, -1/+14Totally awesome.
- windmarble, on 10/26/2008, -0/+8I wish there was some explanation of the experiment going on.
- sundamole, on 10/26/2008, -2/+10Great!
- inactive, on 10/26/2008, -0/+6I wish they had more information on how they were created. The photo's and the experiments.
- Richandler, on 10/26/2008, -1/+7A lot of these are really cool.
- Quasic, on 10/26/2008, -1/+5The oxygen is burned up and is converted to CO2 and to water.
Since there are about 2/3 as many gaseous molecules emitted (CO2) as there are burned (O2), the gas volume changes. As the air starts and ends cool, the change in temperature is not the key change taking place concerning the volume. Also, as the water output is a liquid and liquids have significantly less volume than gasses, the Oxygen is 'burned up' as it changes.
The balanced equation for the change is 2C20H42 + 61O2 --> 40CO2 + 42H2O. - degree, on 10/26/2008, -0/+3IMHO :) the pictures with the magnets and nails tied to strings were pretty amazing. i've never thought of combining those objects in such a way. thinking back, i would be at such a different place in my life if i had realized this sooner.
regret haunts me :[ - ProfessorRiffs, on 10/26/2008, -0/+3I would say they're quite awesome as-is. Black and white isn't inherently artsy-fartsy, it's just a different option than color, and one that is often better suited for the subject matter than color is. Stop trying to be cool and just dig on some groovy *****!
- 16777216, on 10/26/2008, -0/+3The water in the bottom ( top of the inverted glass ) was "sucked" in from the shallow dish due to pressure differences.
It's the condensation in the glass that comes from the burning. - Quasic, on 10/26/2008, -0/+3The one with all the nails tied to thread around the magnet really took me back to science class. I miss those days.
There are some I'd love to frame and hang in my house. - Quasic, on 10/26/2008, -0/+3The oxygen is burned up as it is converted to CO2.
- pikiwedia, on 10/26/2008, -3/+5Nice photos, I think many photos looks much better in black/white.
- theadvinci, on 10/26/2008, -1/+2Amazing collection. I imagine how cool it would be if you could hang these photos in your house, a great interior design element.
- SpeedBreed, on 10/27/2008, -0/+1This should be spread out to all natural science teacher in the world! :-)
If I think back to my schooltime, I had to say that there were precious little experiments shown. - rafe101, on 10/26/2008, -0/+1Okay, I thought he put it in a shallow dish of water, much like the hard-boiled-egg-in-a-jar trick, which would end up looking similar to this. You really get that much water from the burning?
- gordbored, on 10/26/2008, -0/+1great shots especially in B&W makes me wish I had paid better attention in science so i might understand the why and how better
- Kristijan12, on 10/26/2008, -2/+3Awesome it is.
But what is more important is that it is so inspiring. - Scopalamine, on 10/26/2008, -0/+1i knew it, spraying WD-40 into a fire is both a science and an art
- Quasic, on 10/26/2008, -0/+1The water at the bottom isn't a by-product of the burning (mostly, anyway), it has been sucked in from the bottom.
The is very little water actually produced. Far less, in volume, than the gasses being burned up. - phishinphree, on 10/26/2008, -0/+1Hey Caleb, congrats on making dig and good luck in grad school.
- MadOgre, on 10/26/2008, -0/+1SCIENCE: When you see it, you'll ***** bricks.
- rafe101, on 10/26/2008, -0/+1Okay, I see where you're coming from, but the starting temperature of the air in the glass didn't have to be cool. He could have waited before adding the water to the pan. That would have heated the air up, pushed some out the bottom, making this end result more dramatic.
- degree, on 10/26/2008, -0/+1no
- atg360, on 10/26/2008, -3/+1Wow...
And to think, the last science pictures I made were Anatomy! - rafe101, on 10/26/2008, -6/+3About the candle—it's not because it burned up the oxygen (that would mean the atoms that made up the oxygen disappeared somehow), rather, the air cooled down after the candle extinguished and contracted, drawing in some water.
- Elliuotatar, on 10/26/2008, -7/+1I'm sure those photos would pretty awesome if the photographer didn't decide to get all artsty-fartsy and take them in black and white.
