Ideas for Further Experimentation

1. Develop a better earthquake machine which gives more reproducible results.

2. Use larger springs to maximize the weight capacity on the earthquake machine.

3. Try different types of modifications: the tuned mass damper,  the liquid mass damper or a pendulum.

4. Conduct further experiments with the marble base isolator and  build a scale model of a base isolator that may someday be used in real buildings.
