Portable laser pens will be introduced to the world in 2017. These pens will be used mainly for one reason but can be used for many other reasons. The main reason for this pen is to heal big wounds that will cause you to lose an excessive amount of blood. If you are ever in the middle of nowhere hiking or rock climbing and you get a really big wound by falling or maybe worse. Then this pen will come in handy because it will seal the wound by burning it shut. This way you won't bleed out and die instantly. This is also a lot better than using actual fire to heal the wound because you reduce the risk of getting an infection. This little pen can also come in handy for defense against animals, creating fire to cook food and creating fire to boil water.
     I believe that this pen is very important for our future because it will save many lives. A lot of people die while hiking, or doing stupid dangerous stuff. So for those people, this little pen can be very useful. This will improve our future because it can be used for so many things. Not only will it be used for saving lives, but people can use this as a defensive weapon instead of using a gun. It is still dangerous, but it is less dangerous so it reduces the risk of people going on a killing spree. This is a handy piece of equipment that can be used in all types of situations. This little piece of technology can save you from many life problems.
