8- German Scientist Spits Flaming Spores
When flammable powders are dispersed in the air, they can explode. Throughout history, that phenomenon has lead to explosions in grain storage facilities. In this case, the scientist ignites a cloud of lycopodium spores.
7- The PCR Song
Filmed in the style of a celebrity benefit, this music video is a commercial for a BioRad thermocycler, which is essentially a DNA copying machine. During the song, there are tons of great jokes about the particulars of reproducing the genetic material. My favorite: “PCR: When you need to know who the daddy is.” hints that the reaction can be used in paternity testing.
6- Mysterious Reaction Creates an Undulating Brew
In 1973, this spectacular demonstration was perfected by Thomas Briggs and Warren Rauscher, two amazing high school science teachers. When several clear liquids are combined, the mixture quickly changes colors — back and forth — over and over again.

10- Brazzaville, Congo
Air pollution from emissions, lack of potable water and the contamination of the city’s water from raw sewage contribute to the laundry list of health and sanitation concerns for Brazzaville, the capital of Congo. Each of these press upon the life expectancy of the local population
9- Almaty, Kazakhstan
The marriage of petroleum-based industry and insufficient safeguards against pollution sets the stage for an environmental crisis in this city. Toxic waste dumps require a huge price tag for improvement and an even larger price for neglect.
8- Baghdad, Iraq
Poor water quality in Baghdad threatens to exacerbate the the transmission of water-borne diseases in the city. Fatal outbreaks of cholera struck several provinces of the country, including Baghdad from August 2007 to December 2007. The United Nations Environment Programme (UNEP) also says air pollution, resulting from burning oil and aggravated by war, is cause for concern.
7- Mumbai, India
India’s government hopes to transform Mumbai back into a burgeoning metropolis after recent economic decline. A recent private-sector report, Vision Mumbai, proposed changes in infrastructure, pollution control and economic growth strategy, which contributed to the seeking of approximately $1 billion of aid from Indian government.
6- Addis Ababa, Ethiopia
Addis Ababa, the capital of Ethiopia, faces one of the worst sanitation problems on both the continent of Africa as well as in the world. The lack of adequate sanitation programs results in infant mortality, low life expectancy and the transmission of water-borne diseases.
5- Mexico City, Mexico
Mexico City, the capital of Mexico, and the capital of North American air pollution, estimates unhealthy ozone emissions nearly 85% of the year. Mexico’s geographical location–in the center of a volcanic crater and surrounded by mountains–only serves to lock in the air pollution, causing smog to sit above the city.
4- Port au Prince, Haiti
The country’s politically inspired violence and corruption are well documented. Equally dangerous: its air and water. Serving as one of the main ports on the island of Hispaniola, Port au Prince is central to Haiti’s economic development. A lack of pollution controls, however, contributes to the widespread environmental problems confronting the Haitian city.
3- Antananarivo, Madagascar
Madagascar, located off of the southeastern coast of Africa in the Indian Ocean, makes this year’s list with its capital city, Antananarivo. Well known for its variety of unique flora and fauna, Madagascar has often been referred to as the world’s eighth continent, but the effects of the human population are quickly leaving their footprint.
2- Dhaka, Bangladesh
Located in southern Asia, between Burma and India, Dhaka, the capital of Bangladesh battles with the constant threat of water pollution. Surface water is often thick with disease and pollutants from the use of commercial pesticides. With an estimated 150 million people living in a relatively small area, cleaning up the problem won’t be easy.
1- Baku, Azerbaijan
Surrounded by Iran, Georgia, Russia and Armenia on the Caspian Sea, Azerbaijan has long been an oil hub. As a consequence, Baku, the capital, suffers from life-threatening levels of air pollution emitted from oil drilling and shipping.

1- Powdering your roots
If your hairline starts to look greasy, dig up a big fluffy makeup brush and dip it into a pot of loose powder (using translucent powder on your greasy roots). This is something you want do when you don’t have time to shower; it blends into all different hair colors — don’t use baby powder, use translucent as it absorbs oil.
2- Shave with conditioner instead of shaving cream
Ran out of shaving cream? Do double duty by coating your stems with a thick hair conditioner. It softens the hair so it’s easier to shave off and it makes legs feel amazingly silky.
3- Make an egg white mask
To revive tired and dull skin without hitting the spa table, try this: Crack open an egg in a bowl, separate the yolk, and use the egg whites to make a face mask. The proteins help to heal and restore skin’s moisture. Leave it on for five minutes, rinse off!
It’s the protein in the egg white that seals in moisture in your face. So leave it on, then take a turkey baster and rinse off. Its gentle for any skin type.
4- Heat up your eyelash curler
If you have stick-straight lashes, try blasting your metal eyelash curler with a hair dryer for a couple seconds to heat it up so your lashes bend more easily. And use a waterproof mascara — the formula dries faster than other mascaras, so it sets the curl more effectively. It works like a mini curling iron!
5- Spike lotion with bronzer
If you don’t have time to book a self-tanning session, mix a few pumps of body bronzer with regular hand lotion and pat it on your legs for a gradual dose of sexy, beachy color.
6- Soften your body with avocado
Take a ripe avocado, remove the pit and skin, and mash it up in a bowl. Slather all over your body, let it sit for 20 minutes, then rinse off. Your skin will be so soft, since avocado is a natural moisturizer.
7- Amp shine with vinegar
Mix one part vinegar with four parts carbonated water, and soak dry hair. Leave on for 15 minutes before you shampoo to lock in shine and combat dullness.
8- Press a tea bag on splotches
If you’re sensitive or just looking irritated or puffy for some reason, steep a bag of green tea for a minute or two, let it cool down and dab it over your face. The antioxidants in the tea take down inflammation.
9- Use eye makeup remover on stubborn lipstick
Don’t try to rub off red lipstick (which makes it smear across your mouth, which isn’t too sexy). Instead take a cotton ball or tissue and dip it in makeup remover, and just dab to erase the dark stain fast.
10- Use toothpaste on a zit
Use just a pea-size amount, let it sit for 15 minutes to absorb the oil so the pimple won’t get more clogged, then wash it off.
