Pyramid Piles


How it works
Build a triangle-based pyramid using all six pieces of joined balls. Now build a rectangle-based pyramid using the same six pieces.
Things to try or ask around the exhibit
How do the balls fit together differently in each type of pyramid?
Background
Scientists have been studying how to fit the largest number of balls or spheres into the smallest space for almost 400 years.
Finding the science in your world
In Nature, there are many examples where identical shapes are stacked efficiently, such as honeycomb with hexagonal or six-sided cells.
