Ahmed Mohamed is a bright, well-spoken and creative grade 9 student in Texas. One of his favourite things to do is invent and build things. He once built himself an extra long-life battery charger for his cell phone. Recently, he built a clock.
There are some pretty famous clocks in the world: London’s Big Ben, and the clock on the Peace Tower in Ottawa, to name just two.
But the most watched clock in the world may be NASA’s launch clock.
