Fun, learning at science fair

Craig Wallace, left, a senior from Spanish Fork High, explains his nuclear fusion reactor to students from Aspen Academy in Payson visiting the Central Utah science and engineering fair at BYU in which Wallace was a participant. Annika Soderborg, 5, below right, of Heber City is reflected in a mirror as she looks at a science display explaining the most common "linking chemical to make glass." This was among many displays at the fair. Top winners travel to Cleveland to compete for $2 million in awards and scholarships.
