DIY: Bubble recipe and refill station. Love the idea of reusing plastic cups from restaurants as the containers. Keep the bubble solution confined to one big refill container, and no worries about leaky, yucky containers hiding all over the house!
Bubble Mania: You know how crazy kids get when they play with bubbles! I would experiment with other bubble making solutions and find out which one makes bigger bubbles. Use coat hangers to make giant bubbles!
DIY Giant Bubble Blower by egadsman, instructables: Seriously gigantic bubbles. So easy to make with the bubble wand using 2 pieces of dowling/bamboo, string and tape. My dad used to make giant bubbles all the time!
