Recently, the scientists at Spangler Labs had a day where they recollected their fond memories of elementary school. Some thought back to their favorite science or math class, but Steve was excited about the playground equipment. He loved the monkey bars, the swings, and even loved to play tetherball. But, he recalled, his favorite thing to do on the playground was seesaw. Steve’s memories even included a daredevil stunt where he seesawed while it was on fire. He was a regular elementary Evil Knievel. And then it hit him…what if he could use some amazing science principles to make a magic seesaw?
