We suspended a funnel from the ceiling and filled it with paint. The funnel can then act as a pendulum while the paint leaves a permanent record of its path.

We found that we had to make several modifications to get appealing results. Before we began, we thinned the paint to get it to flow more easily. Then, we had to control the height above to floor and adjust the size of the funnel opening to get consistent paint flow.

As paint leaves the funnel, the mass of the pendulum changes, so we added a large weight to prevent significant changes during each painting. Finally, we added a large rim to accommodate more paint for larger paintings.
