Google had a contest to make the largest tower from tiny marshmallows and spaghetti. Another exhibit used toothpicks and gumdrops to make domes (http://en.wikipedia.org/wiki/Dome). When I was 10 years old I climbed to the cross at the top of St Paul's Cathedral dome in London and discovered that it had both an inner and outer dome. The California State Capitol in Sacramento and St Peter's Basilica in the Vatican both have inner and outer domes. So congratulations to anyone who can make a large inner and outer dome from either spaghetti or toothpicks.
Let me know of any other fun tech kids projects in Mountain View in the comments section.
