The Super Soaker toy gun was on the top of nearly every kid's wish list in the '90s, and it made summer heat a literal blast. The game-changing toy has racked up more than $1-billion in sales. It was inducted into the National Toy Hall of Fame in 2015. 

The man who invented the Super Soaker is Lonnie Johnson. While the toy water gun may be Johnson's most widely known invention among consumers, he has made contributions to the world of nuclear and mechanical engineering far beyond pump action toy. 


On this Giving Tuesday, we learned about developments in climate change. The Trump administration recently released a major new report on climate change. The 1,600-page National Climate Assessment was published by the U.S. Global Change Research Program, a group of 13 federal agencies including the Department of Defense, the Environmental Protection Agency and NASA.

Michael Wall, director of farmer services for Georgia Organics, spoke with "On Second Thought" about what this report means for Georgia farmers and what some farmers are already doing to curb the effects of climate change. Kim Wall, a climate scientist and director of the Global Change Project at Georgia Tech, also spoke with us about the major takeaways from this report as well as efforts to fight climate change on Georgia's coast.
