Bump and Roll exhibit

An exhibit that was part of the Nanotechnology: What's the Big Deal? exhibition that demonstrates nanomaterial properties using an everyday object: a leaf of cabbage.

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.

This exhibit was part of the Nanotechnology: What's the Big Deal? exhibition which toured the Arkansas Discovery Network beginning in 2010.

OBJECTIVES

BIG IDEA

Nanoscience is harnessing nanoscale phenomena seen in nature to create new techniques, materials, and products.

LEARNING GOALS

  • Tiny micro and nanoscale bumps can make surfaces water-repellent and self-cleaning.

  • It's fun to play with water on a superhydrophobic surface, but there are lots of practical applications of the technology.

NANO CONTENT MAP

Scientists and engineers have formed the interdisciplinary field of nanotechnology by investigating properties and manipulating matter at the nanoscale.

Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.
