Backyard Rollercoasters

My favorite is # 1.  Which one is your favorite?  Have you ever tried making a roller coaster?

Dedicated to Walt the Man.  He enjoyed inventing and creating things.

  1. We never built a roller coaster, our geodesic dome turned out quite well, though!
    (one of my siblings had read about Buckminster Fuller)
    One of my brothers lived in it for the summer!

  2. I like number 7.

    We never built a rollercoaster, but my dad built a playhouse for us. He built the walls in the garage and then reassembled the whole thing in the backyard. It had windows and a door and electricity. It was great!

  3. I had no idea that people built backyard rollercoasters! Very, very cool. Thanks Cats.
