On Saturday, Dec. 3, the East Cobb-based Atlanta Swim Academy (732 Johnson Ferry Road) will have its annual Underwater Tree celebration from 5-6:30pm.

Bring canned foods to participate, as ASA will be matching every can donate. In exchange for canned foods, participants will receive one glowstick each to decorate the live submerged tree in pool 3. There will be instructors in the water to help young swimmers decorate, but the whole family is welcome to participate.

Bring friends and enjoy swimming with the tree. Free cookies and drinks will be provided in the main hall. A professional Santa will be available for photos (participants can bring their own cameras), and a friendly costumed polar bear will be greeting the kids.

At 6:15, the lights will go out to admire the glowstick tree, and for singing Christmas carols. For more information visit http://atlantaswimacademy.com.
