“I got tired of climbing a ladder six and a half million times a day, so I made a bicycle powered elevator to solve this problem,” he writes.

The treehouse is not yet complete, but Ethan says, “I will be building walls and insulating it in the next few weeks, and eventually I intend to live (or at least sleep) in it. “
In August, 2009, Stefan Schöppers and his team succeeded in breaking the world record for the largest domino toppled in a chain that begins with a “regular”-size domino. Their largest domino, shown in the video above, is 6.40 m (20 ft 11 in) in height.
That record held until an 8m (26 ft 3 in) tall domino was toppled in a on the Dutch National Science Quiz TV show in January, 2013. You can watch that video here.
So how does this all work? Learn more about the science behind the spectacle in this domino chain reaction video by Professor Stephen Morris, and enjoy more videos with dominoes.
Watch out folks. Some guy made a Killer Flying Ostrich. Lot’s of talk about drones out there, but maybe we should be worrying about flying birds that aren’t supposed to fly…
