Inventions & Gadgets!DVD - 2011
Some inventions are earth shattering and have a significant impact on the planet. They make life more convenient, or provide a safer, cleaner environment. Electric cars, personal submarines, and water bikes are new inventions that may become common. With the Tacoma Narrows Bridge as a learning experience, bridge building engineers are using everything from the latest in technology to Lego blocks to design stable and durable bridges. Every invention starts with a great idea!
