Thousands of people being killed weekly,mostly women & children who also get enslaved for labour to extract Cobalt in Congo 🇨🇩 for US and Chinese Companies to make Electronic Products. 💔😭
The next time you see silhouette nails, remember Queen Nenzima of the Mangbetu people of Congo wore it first 😊.
The picture of her is believed to have been taken between 1902 and 1906.

Lonnie Johnson, NASA engineer, invented the Super Soaker. He made your childhood hot summers fun.
African-American engineer and inventor Lonnie G. Johnson was born in Alabama in 1949. He earned his master's degree in nuclear engineering from Tuskegee University, and went on to work for the U.S. Air Force and the NASA space program. After tinkering with the invention of a high-powered water gun, Johnson's Super Soaker became a top-selling item by the early 1990s. He has since been developing the Johnson Thermoelectric Energy Converter (JTEC), an engine that converts heat directly into electricity.
Lonnie George Johnson was born on October 6, 1949, in Mobile, Alabama. His father was a World War II veteran who worked as a civilian driver at nearby Air Force bases, while his mother worked in a laundry and as a nurse's aid. During the summers, both of Johnson's parents also picked cotton on his grandfather's farm.
Out of both interest and economic necessity, Johnson's father was a skilled handyman who taught his children to build their own toys. When Johnson was still a small boy, he and his dad built a pressurized chinaberry shooter out of bamboo shoots. At the age of 13, Johnson attached a lawnmower engine to a go-kart he built from junkyard scraps and raced it along the highway until the police pulled him over.
Johnson dreamed of becoming a famous inventor and, during his teenage years, began to grow more curious about the way things worked and more ambitious in his experimentation—sometimes to the detriment of his family. "Lonnie tore up his sister's baby doll to see what made the eyes close," his mother later recalled. Another time, he nearly burned the house down when he attempted to cook up rocket fuel in one of his mother's saucepans and the concoction exploded.
Growing up in Mobile in the days of legal segregation, Johnson attended Williamson High School, an all-black facility, where, despite his precocious intelligence and creativity, he was told not to aspire beyond a career as a technician. Nevertheless, inspired by the story of famed African-American inventor George Washington Carver, Johnson persevered in his dream of becoming an inventor.
Nicknamed "The Professor" by his high school buddies, Johnson represented his school at a 1968 science fair sponsored by the Junior Engineering Technical Society (JETS). The fair took place at the University of Alabama at Tuscaloosa, where, just five years earlier, Governor George Wallace had tried to prevent two black students from enrolling at the school by standing in the doorway of the auditorium.
The only black student in the competition, Johnson debuted a compressed-air-powered robot, called "the Linex," that he had painstakingly built from junkyard scraps over the course of a year. Much to the chagrin of the university officials, Johnson won first prize. "The only thing anybody from the university said to us during the entire competition," Johnson later recalled, "was 'Goodbye' and 'Y'all drive safe, now.'"
After graduating with Williamson's last segregated class, in 1969, Johnson attended Tuskegee University on a scholarship. He earned a bachelor's degree in mechanical engineering in 1973, and two years later he received a master's degree in nuclear engineering from the school.
Lonnie G. Johnson went on to join the U.S. Air Force, becoming an important member of the government scientific establishment. He was assigned to the Strategic Air Command, where he helped develop the stealth bomber program. Johnson moved on to NASA's Jet Propulsion Laboratory in 1979, working as a systems engineer for the Galileo mission to Jupiter and the Cassini mission to Saturn, before returning to the Air Force in 1982...
