World lightest material

A team of engeniers has developed the lightest material of the world, and aslo has anextraordinarily high energy absorption. It's made out of small microtubes so it's a 99'99% of air, and because this, is the material with the smallest density of the world.

Very light and small, but it has a huge strongness. The structure is the key, "Materials actually get stronger as the dimensions are reduced to the nanoscale," said

Some possible practical uses could be thermal insulation, battery electrodes and products that need to dampen sound, vibration, next-generation batteries, shock absorbers and shock energy.

In conclusion, this material is a good tecnological advance and will be very important.
