You'll never believe these fun and Interesting facts.
1 - Fact: The current American flag was designed by a high school student
It started as a school project for Bob Heft’s junior-year history class, and it only earned a B- in 1958. His design had 50 stars even though Alaska and Hawaii weren’t states yet. Heft figured the two would earn statehood soon and showed the government his design. After President Dwight D. Eisenhower called to say his design was approved, Heft’s teacher changed his grade to an A.
2 - Fact: Cows don’t have upper front teeth
They do have molars in the top back of their mouths though. Where you’d expect upper incisors, cows, sheep, and goats have a thick layer of tissue called a “dental pad.” They use that with their bottom teeth to pull out grass.
3 - Fact: Thanks to 3D printing, NASA can basically “email” tools to astronauts
Getting new equipment to the Space Station used to take months or years, but the new technology means the tools are ready within hours.
4 - Fact: Only a quarter of the Sahara Desert is sandy
Most of it is covered in gravel, though it also contains mountains and oases. Oh, and it isn’t the world’s largest desert—Antarctica is.
5 - Fact: There were active volcanoes on the moon when dinosaurs were alive
Most of the volcanoes probably stopped one billion years ago, but new NASA findings suggest there might still have been active lava flow 100 million years ago, when dinosaurs were still roaming.
6 - Fact: Dogs sniff good smells with their left nostril
Dogs normally start sniffing with their right nostril, then keep it there if the smell could signal danger, but they’ll shift to the left side for something pleasant, like food or a mating partner.
