2may 12, 2015 here's a block of metal that is so light, its density so low, that it floats on water. gupta works with a class of material called "syntactic foam," which are he said it was one of the strongest metals for its weight ever developed.
2may 14, 2015 the material is made of a magnesium alloy matrix which is then turned into foam by adding strong, lightweight silicon carbide hollow spheres

2whether something floats depends on the material it is made of, not its weight. objects float if they are light for their size and sink if they are heavy for their size.
