H&M TV Spot, 'Back to School: Volcanos' Song by Junior Senior

While their teacher remains blissfully unaware of the antics going on behind him as he scribbles away at a chalk board, a group of elementary school students gleefully pour fizzing chemicals into and light the detonating cords of their respective makeshift volcano experiments. The teacher's inattention is rewarded with colorful explosions across the room as the volcanoes all detonate at once -- resulting in a chorus of giggles from his students as he swipes a pile of confetti from his shoulder. This back-to-school season, H&M encourages parents everywhere to find their kids' newest outfits online and in stores.
