Turn water into wine! This simple science experiment demonstrates how fluids with different density can switch places. Fun to use as a magic party trick or as a demonstration for a physics experiment. Watch as the water switches place with the wine, because water has a higher density then wine. You could try using a playing card instead of the thin plastic spacer.

In a fascinating episode of the Blank on Blank animated series The Experimenters, the legendary Jacques Cousteau spoke about his ever-changing search for Atlantis, how the film Jaws was affecting endangered shark populations and the importance of protecting the environment. This conversation took place during a lost 1978 interview with Roy Leonard.
The Cousteau society is dedicated to improving our life and the perspectives of life of our children and grandchildren by protecting the water system of this planet by all means. It intends to achieve these goals by using all the communication methods possible. Television. Film.
Backyard Ballistics by engineer William Gurstelle is a guide on how to make 16 ballistic devices at home, from potato cannons to Cincinnati fire kites. The expanded 2nd Edition goes on sale September 1.
Clear instructions, diagrams, and photographs show how to build projects ranging from the simple match-powered rocket to the more complex scale model, table-top catapult to the offbeat tennis ball cannon. With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind the projects, and profiles scientists and extraordinary experimenters such as Alfred Nobel, Robert Goddard, and Isaac Newton

The Backyard Scientist, an audacious experimenter who often tests out ideas submitted by viewers, poured molten aluminum into the cores of a cantaloupe and a honeydew melon just to see what would happen. As it turns out, the cooled metal came out looking like hand grenades.
Pouring molten aluminum in a watermelon turned out to be really popular, So I poured aluminum in two more melons, honeydew and cantaloupe. It turned out really cool, giving a perfect cast of the inside of a melon. It looked just like a hand grenade!
Earlier this year, The Backyard Scientist poured molten aluminum into a watermelon with fascinating results.
On a recent episode of The Experimenters, an animated interview series from the creators of Blank on Blank (previously), the incredible Jane Goodall discusses her love of animals, how the late Louis Leakey changed her life, and the strength of her beliefs in a 2002 interview with Science Friday host Ira Flatow.
I think I’d like to be remembered as someone who really helped people to have a little humility and realize that we are part of the animal kingdom not separated from it. When I do go back to Gombe it’s to be in that timeless world where it’s soft and where life is entwined and you actually see the pattern of nature. I always feel this great spiritual power which I believe is around.

The Darwin Manuscripts Project at the American Museum of Natural History has released “the world’s first and only large collection of full color, high-resolution images of faithfully transcribed Darwin manuscripts.” The project designed to share the work of famed naturalist Charles Darwin is ongoing with frequent additions of new material.
In these documents, you can trace the development of Darwin as a thinker and you will meet Darwin as a keen-eyed collector, an inspired observer, and a determined experimenter. You will also find Darwin the shrewd reader, attuned to his cultural context, and the strategic writer, ever reconsidering and revising.
The AMNH Darwin Manuscripts Project is a historical and textual edition of Charles Darwin’s scientific manuscripts, designed from its inception as an online project. The database at its core—DARBASE—catalogues some 96,000 pages of Darwin scientific manuscripts. These are currently represented by 16,094 high resolution digital images. Thus far 9,871 manuscript pages have been transcribed to exacting standards and all are presented in easy to read format.
Volunteers and interns are invited to train to work on the project at the Research Library at the museum.

Craig Benzine, also known as Wheezy Waiter, the host of the Mental Floss series “Big Questions” answers a viewers question as to whether or not ginger ale really helps to aid gastrointestinal disturbances and how it goes about doing it.
There are few things going on here that can affect your stomach – carbonation, ginger and then a combination of those two things in ginger ale. and whether or not any of these help is actually still being debated in the medical world. …A 2011 study examined 744 cancer patients who are receiving chemotherapy which typically makes people nauseous. Some were given a placebo and three others were given varying amounts of ginger. The study was a randomized double-blind, meaning neither the experimenters nor the patients knew which groups people belonged to. According to the results all doses of ginger significantly reduced acute nausea severity compared to placebo. …
Since ginger has been shown to help with stomach issues in some cases, try to find ginger ale with ginger root in the ingredients.
Doctor Oliver Sacks, the renowned neurologist and author of such best-selling works as Awakenings and The Man Who Mistook His Wife for a Hat and Other Tales how those with afflictions find way to create a new normal within a community of their own, using the H.G. Wells story “The Country of the Blind” to emphasize his point during a 1996 interview with Henry Tischler of WGBH-FM. This episode is part of the The Experimenters, an animated interview series from the creators of Blank on Blank.
I’d had a sort of haunting memory of an H.G. Wells story called The Country of the Blind, in which a lost traveler in South America blunders into an isolated mountain valley and finds a whole community of blind people …the traveler regards himself as the norm and a superior, and, in fact, he finds that he, that the people in the village are so well adapted to their condition, that he is the one who blunders and makes mistakes and is regarded as abnormal. And I certainly sometimes have the feeling that the achromatopes felt that we, so-called normals, wasted a lot of time talking about color, referring to color, paying attention to something which for them was nonexistent, which they could only imagine as trivial.
