This falls into the category of “don’t breathe” or “we thought houses of cards were difficult;” these artists have taken it to the next level. In 2010, artist Peter Root spent 40 hours standing 100,000 staples on end to build a miniature city inspired by New York City that he called Ephemicropolis.

Stan Munro builds famous landmarks out of toothpicks. What started as a 5th grade art project turned into Toothpick City. The City features more than 50 famous structures from around the world (the Space Needle, Eiffel Tower, Golden Gate Bridge) made out of six million toothpicks and 170 liters of glue. Now on permanent exhibit in a Spanish museum, Munro has continued crafting, including Toothpick City 2 at the Museum of Science and Technology in Syracuse, New York.

Artist Meschac Gaba made a large-scale model of a fantasy city featuring landmark buildings from around the world (Taj Mahal, Sydney Opera House, Empire State Building). Seems simple enough, right? What if I told you it was all made out of sugar? Meschac Gaba: Sweetness includes 600 buildings, measures 30 feet by 20 feet, and took two years to build. Talk about sweet!
