A toy launch apparatus for discharging soft foam darts, the launch apparatus having a cylinder, a piston, a launch spring and a dart tube. An air chamber with variable volume is formed between the cylinder and the piston and is divided into two or more sections, a first section where there is little or no resistance to relative movement between the cylinder and the piston so that there is a momentum gain, and a second section where there is rapid compression and increasing pressure to cause a loaded dart to be discharged.
