Scuba technology enables divers to explore underwater depths, interact with oceanic species, and survive for days in giant vats of bouillabaisse while they eat their way out. Gird yourself against the dangers of cavernous cookware with today's Groupon: for $10, you get a discover-scuba experience at Ocean First Divers, in Boulder (a $20 value).

Ocean First Divers introduces students to the watery wonders of scuba diving with the help of seasoned teachers and a Professional Association of Diving Instructors five-star training center. The discover-scuba experience includes equipment rental, brief instruction on diving concepts, and a two-hour dive in Ocean First's 50-foot-long indoor dive pool, which is kept at a balmy 87 degrees, the temperature at which polar bears melt into dolphins.

The friendly, experienced staff is comfortable training aquatic amateurs of most ages, and Ocean First has equipment to fit water-treading tots as young as 8. Make sure to bring a towel, bathing suit, and completed release form to class, then set about developing the skills that may some day be required for life in an underwater society ruled by mermaid dictators.
