Play-Doh that can hold up a Bridge ?

Plastic like Steel

       As a kid, I loved playing with Play-Doh.  My imagination would run wild and I would create amazing looking helicopters or airplanes, sometimes creatures.  At Yale, they were able to develop a metal alloy that molds as efficiently and quickly like plastic.  The material is known as BMGs, bulk metallic glasses.  Besides material, the method of molding is what makes it so flexible.  They method is called Blow-Mold, which is then subgroup into extrusion blow molding, injection blow molding, and stretch blow molding.  In extrusion blow molding, the material is melted and poured into a parison, a hollow tube, and air is forced into the parison making it into the shape of the tube.  For the injection blow mold method, where material is melted onto a rod, called a preform, then placed inside another machine which blows the cooling material into the desired shape.  In the stretch blow molding, it uses a preform(obtained from injection mold), places it inside the desired shape and high pressured air is pushed in, making the complete form. *Source*

      With this new discovery, created by scientists in Yale University, production of strong metals will become more cost efficient and shapes would be easier to make.  This is the ideal invention that our future looks to, being able to produce great durability, while paying only a faction of the cost.  All appliances, parts, structures, and toys would become much more affordable.  This type of material would be best used for restructuring buildings or mending buildings, since it can be easily molded, while producing a reliable sturdiness.  However, I don't think it can be used for building skyscrapers or buildings, because it doesn't sound sturdy knowing that it can be easily manipulated.  It can also become easy targets for terrorists and easily be put as a hostage.

Cure to Scars?

Skin-cell Spray Gun

Skin gun a product of studying stem-cells.  It is a gun that takes the skin cells around the 2nd degree burned area and recover its skin.  This invention is being used a lot in battle, because there are many burn victims from suicide bombing and bombing in general.

I think this is a great invention, because everyone wouldn't be afraid of the fire or the phrase " If you can't stand the fire, get out of the kitchen", haha, just kidding.  But seriously though, people would not have to worry about getting burned by the stove or worry about scars or scabs forming.

Besides being used for burns, I think this invention is a great start for the cure of acne scars.  Being a person that has been suffering from acne for 6 years now, I believe that this gun could be the invention that can help everyone recover from their acne scars and have a clear face again. 

With the invention of Skin-gun, it might even take some of the business from plastic surgeons.  People wouldn't have to remodel their faces due to the scars, because all they have to do is just rebuild their skin.  This type of treatment is all natural too, because it is using the skin that is around you and just stimulating the area to grow more of what you have.

In addition to acne-scar treatment, it can be used on people that have eczema.  Eczema is when the skin is easily irritated and inflamed.  When people scratch their skin, they can easily cause scars as well as have different shades of skin color.  I think this gun will be very useful for people that are suffering from that disease.
