The biggest challenge faced by travelers especially those who like to have a backpacking trip is how to ensure a steady supply of clean clothes. Now, thanks to a great invention called Scrubba Wash Pack, that worry may be a thing of the past.

The portable washing machine was invented by Ash Newland in 2010, while planning to climb Mt. Kilimanjaro. Struck by the limited packing space, he got inspiration from traditional washboards to create a bag that could be used to clean clothes. Then he quitted his career as a lawyer and focused on perfecting the bag’s design. By 2012, the bag was ready for the public. It weighed only 180 grams and required very little storage space, making it perfect for anyone wishing to travel light.

Not surprisingly, the bag worth 55 dollars was in instant hit with travelers, university students and even passengers. However, Newland was not satisfied. He still saw a disadvantage with his invention—dirty clothes had to be carried around in a separate bag! The recently introduced Scrubba Wash Pack solves that problem.

In order to make the pack active, dirty clothes are placed inside the bag along with two or three liters of water. The bag is then shut tightly to ensure all air is squeezed out and the clothes are massaged for a few minutes. After a quick wash, they are clean and ready to be dried. According to Newland, the pack can clean anything from jeans to smelly socks! What’s even more amazing is that with a capacity to hold 13-liters of water, it can be used to wash more clothes at a time.

The best part is that the 99-dollar pack that will be available for sale later this year, only weighs 300 grams and is completely foldable, making it easy to store when it’s not in use. With the Scrubba Wash Pack, wandering through foreign cities searching for a washing shop, or paying for washing machines may soon be a thing of the past!

After successfully serving their term for four years, military service men and women are given the choice to stay in the military or return to civilian life.

For some, having to readjust to civilian life is one of the most challenging assignments our returning soldiers and marines(水兵) will ever have to undertake. While people may think that readjusting should be simple, they must take into consideration all the physical and mental stress our serviceman went through.

Post-traumatic Stress Disorder(创伤后应激障碍), or PTSD, is a mental disorder that can occur following the experience or witnessing of life-threatening events such as military combat.

Most survivors of trauma return to normal given a little time. In the military, the marines are given a two-week course on how to return to civilian life.

Unfortunately, some will have stress reactions that do not go away on their own, or may even get worse over time. These individuals may develop PTSD. People who suffer from PTSD have difficulty sleeping because they are often reliving the experience through nightmares and flashbacks, and feel deserted or often stand off, and these symptoms can be severe enough and last long enough to significantly damage the person’s daily life.

Fullerton College, like most college, has its own Veteran’s(老兵) Office. Ray Bustos has been running the office for 3 years. Bustos acts as a liaison(联络) for the school and the veteran students. He makes sure the veterans returning to school get the right benefits. There are various types of financial aid for soldiers and marines. He strongly encourages the use of the Veterans Affairs website. The website is very informative and extremely helpful for veterans as well as for friends and relatives of veterans who want to learn more.
