Manatees are commonly mistaken as mermaids because both become speechless on land. Watch them communicating in their natural environment with today's deal: for $22, you get one Discover Scuba class at Underwater Connection ($45 value). This introductory evening class, scheduled every few weeks, provides comprehensive instruction and in-pool dives at any of the three locations in Delafield, Menomonee Falls, and Hales Corners. Students as young as 12 can attend, and because there's no purchase limit for this Groupon, feel free to bring someone else's family.

Strap on some aqualungs and submerge yourself for one to two hours of supervised pool time. Experienced instructors encourage you to cheat on your land love during one hands-on evening. They'll teach the gadgetry of underwater breathing, aquatic safety precautions, and the basic skills required to take an assisted dive. Throughout the evening, feel free to ask questions regarding the equipment, the experience, or the possibility of further scuba training. Students should bring a towel and swimsuit for class, but don't have to worry about bringing an ocean.

This Discover Scuba class can be used as a stroke toward beginner classes and eventual certifications; Underwater Connection offers a wide range of additional classes. Whether you've always admired the sea or you've never experienced what water smells like up close, give scuba diving a shot with today's Groupon.
