A crowd-pleasing, if slightly formulaic, documentary in the vein of Spellbound, Science Fair follows a group of gifted school kids from around the world as they compete for recognition in the International Science and Engineering Fair in LA. A German 17-year-old has potentially revolutionised aeronautical engineering; a pair of impoverished kids from Brazil have devised a treatment for the Zika virus. Rampaging teenage hormones are rife in this very likable portrait of the geeks who may shape the future of the world as we know it (or may just go on amusing themselves by programming their calculators to generate random Shakespearean insults).
