Neutral Buoyancy defined is the equal tendency to either float or sink. Divers and astronauts experience the same feeling. Even though being underwater and being in space is different, astronauts feel the weight of their suits as well as the drag of the water very similar to scuba divers. This helps with important training for astronaut preparation mentally and physically. The Neutral Buoyancy Laboratory (NBL) located at the Sonny Carter Training Facility near NASA’s Johnson Space Center in Houston, Texas, USA supports this training.Photo Credit: PADI.com
Plastic Bank helps people earn a living going door-to-door or through the streets collecting plastic in third world countries. By doing so, plastic never leaves land that could prove harmful to the ocean and its sea life if it were washed out to the ocean during the rainy season from rivers.
At the end of the day, the collectors bring it back to one of the Plastic Bank’s locations, where it is weighed. The value of the plastic is transferred into a personal online account for the collector.
