Does designing a material on the nano or molecular scale really do anything productive on our level?
By engineering an alloy on the atomic level, the metal gains a list of novel properties that can be used in several applications. Visit http://www.liquidmetaltechnologies.com to learn more about a commercial application of this process.

Elastic Strain Demo • Gather several types of metals to compare with the new alloy: • Aluminum • Brass • Copper • Steel • Titanium • Collect a clear tube, steel ball and a timer to time the bounces.
Elastic Strain Demo • Drop the steel ball from the same height on each type of metal. • Count the number of bounces and record them. • Use a computer recording software to record the bounces and time. • Draw a bar chart displaying the bounces for each metal. • Discuss applications for a metal that repels forces, doesn’t rust, and has low friction.
This is a set of audio recordings of several metals bounce test. It is easier to count the number of bounces visually rather than audibly. Image by HighPoint Learning
