Bump and Roll

Description: 

Bump and Roll is an interactive exhibit that demonstrates nanomaterial properties using an everyday object: a leaf of cabbage. The nanoscale structures on a cabbage leaf cause water to bead up and slide off its surface. Scientists are replicating these “superhydrophobic” properties with nanotechnology. Drip water onto a cabbage leaf, and change the angle of the surface to see how the droplets behave. Find out about the super-small bumps that make this surprising behavior possible. Cabbage leaves must be replaced every few days, and Bump and Roll’s water tank must be refilled occasionally.

About Exhibits

An Exhibit is a visitor experience that may take many formats such as a display of objects or interactive components; it may include graphic panels or multimedia components; it is usually an un-staffed visitor experience. A group of themed exhibits makes up an Exhibition.

The exhibits created by the NISE Network were developed through a process of prototyping, audience evaluation research, educator peer reviews, and in-depth partnerships with scientists.
