Bubble Blowing is a wonderful outdoor activity for children. Bubbles get kids running, jumping, and smiling.  Blowing bubbles also directly supports language development by teaching children how to shape their mouth and/or strengthen their tongue, ask for things they need, or be introduced to new vocabulary through a fun game. Additionally it teaches children social skills such as taking turns and eye contact.
For young toddlers who are still figuring out how to use a small bubble wand you can try berry baskets. The fun thing about using a recycled berry basket is that bubbles form in clumps and come out in clusters vs. the single bubble you might get off a wand.
I have tried a few homemade recipes for bubble making but my favorite bubble mix is Gazillion bubbles.
