Spider silk has the ability to absorb immense amounts of kinetic energy, which means that it’s great for blast protection. Density: Strong as it is, the silk is also incredibly light. It is much lighter than steel itself, and its density (1.31 g/cm3) is actually one-sixth of the density of steel.
How much does spider silk cost?
Long term, spider silk developers have to target a cost of less than $10 per kg if their material is to compete with conventional textiles on a mass-market scale, Oh says. Spiber has publicly stated that its commercial-scale silk will cost $20–$30 per kg.

The spider’s central nervous system is made up of two relatively simple ganglia, or nerve cell clusters, connected to nerves leading to the spider’s various muscles and sensory systems.
