OTTAWA Mastering a skill usually takes years of experience. Practicing, making mistakes. Enjoying successes and grinding through failures. For Marcus Brun, it s only taken months. The most impressive part? He s seven years old. In the midst of the COVID-19 pandemic last summer, one of Marcus friends challenged him to make a paper airplane. The first ones I started making were the ones you fold in half, and half…the basic ones, he says. In October, Marcus started to watch YouTube tutorials on how to make designs that are more complicated. His curiosity quickly turned into a passion, sometimes folding planes for up to eight hours a day.
