Hubba Bubba and the Big Bubbles
From Scandinavia, a nice advertainment website for kids. Learn everuthing you need to know on the Hubba Bubba Big Bubbles (if you speak Norwegian or Swedish). I especially liked the “school” section, where they actually teach you how to make a bubble with a chewing gum (see screenshot below).
The agency behind it is B-Reel which, btw has a quite interesting portfolio.
