Unlike the ability to blow bubbles, infants aren't born with the ability to blow glass, and therefore must spend their babyhood exhaling awkward artwork that just shatters midair. Acquire the ability to blow beautiful glass with today's Groupon: for $99, you get a four-hour level one, two, or three Intro to Glass Blowing class at Revere Glass School in Berkeley (a $220 value).

Revere Glass School is run by a team of glass-crafting masters who provide expert advice for amateur and accomplished artisans alike. During a four-hour class, beginners get to create their own jewelry or sculpture in a supportive, small-group setting that nurtures students learning to manipulate molten glass for the first time. Burgeoning glass-blowers with some experience under their belts who have completed Intro to Glass Blowing one or have comparable experience can opt for the level-two class, during which they'll undergo hands-on sculpting sessions to create an implosion marble, a jar or shot glass, or a perfume bottle. Seasoned sculptors who have completed Intro to Glass Blowing one and two or have equivalent experience can choose the level-three class to assemble an eye-catching goblet, ideal for opulent beverages or serving Yoo-hoo to Queen Elizabeth. All necessary oxygen, propane, materials, and encouraging back slaps are included.

The glass gurus at Revere have assembled a collection of high-quality equipment and non-intimidating heat sources to ease novices into a precise, demanding art where careless mistakes can spawn sentient mirrors. Bearers of today's Groupon also get a 15% discount on any additional classes.
