How did Spider-Man get his power?

He gained his powers at the science museum, Peter was bitten by a radioactive spider. The spider bite gave Peter spider like powers. Spider-Man has spider like abilities including superhuman strength and the ability to cling to most surfaces. He is also extremely agile and has amazing reflexes. Spider-Man also has a, "spider sense," that warns him of impending danger.

Spider-Man has supplemented his powers with technology. Being a brilliant chemist and scientist, Peter has made web-slingers, bracelets that shoot out a sticky webbing, allowing him to swing from building to building and ensnare opponents. He has also developed stingers that shoot powerful energy blasts that can stun foes.
