Torre Major, Mexico City
This is the Torre Major
in Mexico City, Central
America.
It is said to be the
strongest building in
the world.
Yet it is built in one
of the world’s most
unstable areas.
Q: How is it so strong?

in your ‘Engineer’s
Factfile’.

In Kobe Japan

built some
amazingly

Spaghetti and Marshmallow
Earthquake Proof Buildings
• Design, build, and test a model structure
made out of uncooked spaghetti sticks and
marshmallows!
• Your model will be tested on CRAP’s stateof-the-art earthquake simulator machine:
"The Shake Table."
• Your model should be able to withstand a
10 second earthquake without collapsing.
• You will be competing against other teams
by attempting to build the best structure.
• You and your team mates will give a brief
presentation prior to the final test.
