Battery free calculator!

It's the back to school sales tax holiday in Georgia! I scored this handheld calculator that doesn't need a battery!

NOTE: I like to go to Starbucks, sit down between two people using their laptops, start playing with my slide rule while furiously scribbling down numbers and math formulas on a yellow legal pad using my mechanical pencil. Then I will suddenly stop, grab my cell phone, call home and shout ... "It's 7.69915! The asteroid will strike earth exactly 32 and a half miles northwest of Chattanooga, TN!
