It has a charged track inside it, charged with lithium-ion batteries fitted in gun.
Bullet is made up of aluminium and small button batteries are fitted and connected to body of bullet. Capacitors are used to create high voltage and high current fitted in gun charged with batteries..
When trigger is pressed, tracks inside the gun are heavily charged with high voltage and high current, bullet travels with high speed by principal of electromagnetic induction (as happen in black holes)
Guns batteries, whose supply is DC is changed with the help of electronic circuit to AC with variable voltage and variable frequency..
Frequency and voltage of supply is varied in such a way that the induced emf in bullet will launch the bullet with speed of 10000 RPM..
