Today we are making metals that are lighter than Styrofoam, so light they can sit atop a dandelion puff and be blown away with a wisp of air — so light that you can make a car that two people can lift, but so strong that it has the crash-worthiness of an SUV.
En la actualidad podemos hacer metales más ligeros que el poliestireno. Tan livianos que se pueden colocar en una flor diente de león y mandarlos a volar con un soplo de aire.
