If foam noodles can be found floating on the surface of almost every pool, think how many perfectly salted meatballs must be at the bottom of the ocean. Discover the sea's sunken treats with today's Groupon: for $35, you get an introductory skin-diving class (a $75 value) from Scuba Extreme, located in Middleburg. Dives are held at an off-site location—contact Scuba Extreme to coordinate a meet-up or transportation to the site, generally located about an hour from the store.

The friendly sub-surface staff and committed conservationists at Scuba Extreme spread their waterlogged gospel of underwater maneuvering through safe and fun diving instruction. In the "Skin Diver" course, budding sea-people will learn the basics of snorkeling and free-diving techniques. Instructors will equip students with a mask, snorkel, and fins, and then lead participants through the basics of submerged breathing and safety. The class lasts between two and three hours, or approximately one year in the life of a fantail guppy.

Skin diving supplies an exciting, hands-on aquatic alternative to surfing channels, parasailing the Web, or diving into ball pits. Finally put to rest a persistent fear of bathtubs and really big puddles with a skin-diving class from Scuba Extreme. Call ahead to schedule your class and location.
