Here is a link to a shake table that uses 4 rubber balls, 2 rubber bands,
and 2 stiff boards (such as cut apart binders or thin plywood scraps):

It is about as simple as you can get for preliminary investigations.

Has anybody got a really good but simple design for an earthquake shaker
table on which to test student constructed towers? I have access to tools
and materials but am limited on time, of course.
