Stargazing in the backyard takes on new meaning with this incredible rocket ship.

Built between 2009 and 2010 by Jon Howell and his friend Jeremy Elson, this rocket ship is tucked away in the Howell's yard in Seattle's Ravenna neighborhood.

Called the "Ravenna Ultra-Low-Altitude Vehicle" or RULAV, the 15-foot rocket ship has a working pilot control station, specially designed for Howell's son Elliot, with light-up switches, knobs and buttons.

Takeoff and docking sequences in the rocket ship also look and sound real, with the help of a powered subwoofer for the simulated rocket engine’s rumble and an augmented paint-shaker for the vibration of the engine. Eerie lights engage and look especially magical at night.

Conceived 20 years before he actually installed it, Steve Wienecke, a retired cage fighter made his dream of a giant pool table come true in his backyard.

At four times the size of a typical table, this larger-than-life table wasn’t made just for kids, but Wienecke did tell Rural Missouri Magazine, “Long arms are definitely an advantage. But anyone can play, even kids. My kids and grand kids love to play.”

According to the Rural Missouri Magazine, Wienecke has named his game “Knokkers,” and it is played much like pool, only instead of pointing a stick to guide the rest of the balls into pockets, you roll a bowling ball at them.

Built as an homage to the famed Fenway Park, Little Fenway, a wiffle ball stadium in Vermont, is a near-replica at 23 percent the size of its namesake. Also, it’s all in one family’s backyard.

Granted, Pat O’Connor, the father who built it, had a rather nice, large yard for it. The field sits on 10,000 square feet of land. Visitors are invited to come enjoy Little Fenway as it accommodates 1,000 at capacity.

‘La PetiteMaison’: The Kolbecks

(11Alive News)

This little house, dubbed “La Petite Maison” sits on the property of the Kolbeck family in Marietta, Ga. Originally assigned to Sicily Kolbeck,13, as a school project by her teacher -- who also happens to be her mother—the construction of the house took on a life of its own, and became a true labor of love.

Sicily and her father worked on the house tirelessly together until a tragic car accident last year took Mr. Kolbeck’s life. After his death, Sicily decided to finish the house on her own as a tribute to her father.
