Metal so light it floats on dandelion fluff

World's lightest material is a metal 100 times lighter than Styrofoam (Science Daily)  Only one part in ten thousand of the micro-lattice is made of metal.  The rest is air.

'It takes more than 10 seconds... to fall if you drop it from shoulder height.'"  LAT

This property is extraordinary  for absorption of sound, vibration and crushing.  It's lightness will solve problems in air and space transport. It rebounds fully from being squeezed over 50%.  You can imagine uses.

Almost as light, an aerogel dubbed "Frozen Smoke" was discovered last winter
