Bill Nye The Science Guy bikes down a long road in wide open country to demonstrate a scale model of the solar system – a classic clip. Total distance of his ride to Pluto, back before Pluto was known as a dwarf planet: almost 2.5 miles (4 kilometers).

The world record for longest throw of a paper airplane has been broken.

Joe Ayoob throws a John Collins design, officially breaking the world record by 19 feet, 6 inches. The new world record, once verified by Guinness, will be 226 feet, 10 inches. The current record is 207 feet and 4 inches set by Stephen Kreiger in 2003.

Ayoob was a quarterback for two seasons at Cal and played three years of arena football as a professional, so he knows about throwing… and knows about paper airplanes: he used to make them and throw them while he walked home from school as a kid! The airplane’s designer, John Collins, is known as The Paper Airplane Guy and has studied both origami and aerodynamics. 

"A lot of people could throw this plane and get some pretty crazy distance out of it," Ayoob said. "But in order to achieve the distances we were trying to reach, it took a pretty precise throw, and it took a lot of strength. … There’s a lot of finesse involved, so it’s kind of blending power, balance and control while you’re throwing this fragile, little paper airplane."

It takes the moon about 27 days to orbit the Earth. What makes it go round? It is the gravitational attraction of the Earth on the moon. Due to the moon’s velocity, the Earth keeps pulling the moon towards it without the moon actually getting closer to the Earth. This is similar to how satellites orbit the Earth.
