President Obama in April 13th, according to the United States Washington Post, a small Chinese sister in Seattle produced a space launcher, invited by the White House Science Exhibition, and received by President Obama of the United States.
it is reported that when the US president met with two people in 13 local time, he praised the results of the two men's "incredible". "You're great!" Obama said.
this is the 9 year old Chinese sister, Jin Benli Yang and her 11 year old sister Rebecca Yang. The old sister "Loki" photos of the older sisters and the Lego blocks have formed a "loge Lego emitter", which will also be displayed at the White House Science Exhibition. The
sister flower launchers are equipped with a GoPro camera, a GPS tracker, a flight calculator, a temperature and pressure sensor, a Lego R2-D2 small robot, and a cat "loge". In September last year, the spaceship, together with the launcher, tied up a hydrogen balloon and floated to a height of 78 thousand feet. The spacecraft records the coordinates, temperature, speed and pressure of the edge of the space, and then sends back the data.
this sister's scientific experiment was widely paid attention to the video clip produced by family, most of which were made by two sisters, and dad was responsible for making the wood into a hull and inflating the balloon. The two sisters were responsible for calculating the work and various tests before launch. Two people also had a special binder to store all kinds of notes, plans and data.
these sisters say that science is their favorite subject. Sister Jin Benli said he wanted to become a robot engineer when he grew up, specializing in the direction of biological robots.
two people were invited to NASA's Jet Propulsion Laboratory before visiting the White House.
