Interesting Tsunami Facts from Virtual Tsunami:
  1. A tsunami is a sea wave caused by an underwater earthquake or landslide displacing the ocean water.
  2. Tsunamis have nothing to do with tides.
  3. Often the seismic waves are unnoticeable until the energy of the wave reaches the shallow waters of the coastlines.
  4. When a tsunami approaches shallow water, it can reach as high as 100 feet or more.

We used an old ice cream bucket and didn't cut out a hole.
