A Smashing tradition: MIT Students Drop Piano
One of the highlights of the school year at the Massachusetts Institute of Technology only lasts a few seconds but has a big influence. Residents of an MIT dormitory dropped an upright piano from their roof on 26^th April to celebrate the last day students can drop classes without having them appear on their college report.
About 200 onlookers watched as the piano crashed into a second piano, a baby grand, positioned on the ground six stories below for a better smash. People scrambled (争先恐后) for souvenir pieces-keys, hammers, strings and splinters. The tradition began in 1972 at the Baker House dormitory and has been observed irregularly until 2006 when it became an annual event.
Crafton Family Comes Back Home after 7 Years at Sea
While most of us will love to go on a vacation for a week or two on a small private sailboat, without doubt, spending seven precious years on sea is something most of us will never imagine or dare to do. However, that is what an American family has done. Tom Crafton and Kathy Crafton along with their three children have traveled across the world on their 43-foot sailboat named Nueva Vida. Over the past seven years the family had sailed 30,000 miles and visited more than 20 different countries. The family has recently come back to their homeland.
