What better way to launch your newest magnetic construction toy than to piggyback onto the 30th anniversary celebration for Toronto’s CN Tower – by staging a contest whose winner builds the tallest replica of same? Toronto-HQ’d MEGA Brands (formerly Mega Bloks) will do exactly that today and showcase its imagination-sparking Magnetix system during a weekend of special events. Plus, merely uttering the word ‘Magnetix’ will win a special admission price of three visitors for $30 to the tower’s lookout and glass floor levels. Deserving of a bow for MEGA Brands’ recent promotions is sizzling hot, Amsterdam-based Strawberryfrog.
