Lamp powered by 300 live apples and other great photographs of science in action

Check out these amazing photographs by Caleb Charland.

And the remainder here from a collection called “Demonstrations”

Superhydrophobic carbon nanotube water droplet bouncing GIF goodness.

“Superhydrophobic surfaces are those which repel water to such a degree that droplets roll right off. The forces of surface tension actually overtake the friction of the surface the droplet rests on, and this is what keep the droplets from wetting.”

Like most heavy metals, Thallium is highly toxic and should not be used on breakfast cereals. #funny

Sound advice: Keep Calm and Follow the Laws of Thermodynamics

Not that you could disobey this or anything…

A Science Video Classic: Gummi Bear in Potassium Chlorate

CLEARLY worth repeating in my own lab (esp. for our school programs, assuming we’re cleared for safety issues). Perhaps also a segue for talking about alternative energy?

Traffic light in an Erlenmeyer Flask

A solution of glucose, sodium hydroxide, and indigo carmine, when shaken, will change from yellow to red to green. Left to sit, it will revert to red again, then yellow, and the process can be repeated. The indigo carmine is green when oxidized, yellow when reduced, and red in the intermediate semiquinone state

Wonderful artwork in this brilliant history of organic chemistry slideshow.

“Vladimir Markovnikov,a chemist and political progressive, was outmaneuvered by the crafty and conservative Aleksandr Zaitsev. Both men would go on to fame as discoverers of significant trends in chemical reactivity and organic chemistry students today still learn “Zaitsev’s Rule” and “Markovnikov’s Rule.”

“So, organic chemistry has come a long way from its early days. It might have reached its peak,in a certain sense, around 1972, when Robert Woodward of Harvard and Albert Eschenmoser of the Swiss Institute of Technology synthesized the very complex molecule we know as vitamin B-12. Ever since, it has been widely accepted that organic chemists can make pretty much any molecule that occurs in nature. That is really something!”

Not “Snakes on a Plane,” but rather, “Salt on a Plane”…

…looks like this.

“…a grain of sodium sulfate and sodium chloride (salt) while researching jet turbine safety. Jet turbines become very hot when in use and are also exposed to the atmosphere. This combination can lead to compounds such as salt encrusting the turbines. Rosier and her colleagues reproduced and photographed one such salt grain in the laboratory.”

I thought this was very very funny, which I think must say something about my personality.

This is how chemists propose.

Using Heineken as a high efficiency solvent. #chemistryisawesome

Curious whether the water/5% ethanol mix was done first (and therefore leading to the beer and wine experiments), or whether it was the other way around.

A mundane tragedy is actually a great lesson in thermodynamics (or I’m such a geek)

First, show your audience this awesome strip:

Next, discuss the first law of thermodynamics, systems, dQ and all of that. Then, wait for the merriment to ensue.

Test it, not taste it! The origins of Sucralose.

“Sucralose was discovered in 1976 by scientists from Tate & Lyle, working with researchers Leslie Hough and Shashikant Phadnis at Queen Elizabeth College (now part of King’s College London).[3] While researching ways to use sucrose as a chemical intermediate in non-traditional areas, Phadnis was told to test a chlorinated sugar compound. Phadnis thought that Hough asked him to taste it, so he did.[3] He found the compound to be exceptionally sweet.” (From wiki)
