Another stocking stuffer option that can occupy kids during a long holiday car ride is a game. Many manufacturers now offer travel or handheld electronic versions of favorite board games small enough for a stocking. Card games are another good option. For those going for a nostalgic twist, try yo-yos, bouncy balls, marbles, jacks and even a Rubix's Cube. While not actually a game, bubbles can provide hours of fun. Some varieties are even scented or come with odd-shaped wands to produce different bubble shapes.
