We finally know why weird silver balls have been appearing on beaches in Queensland,Australia,experts have told Metro.

Six metal spheres washed up on Friday,Saturday and Sunday near Forrest Beach,a seaside community 10 miles southeast of Ingham.

Firefighters in hazmat suits,space experts and national emergency officials have been scratching their heads as to what these objects are.

Five of the chrome balls were placed in drums,with the police enforcing a 160ft exclusion zone over fears they’re ‘toxic’.

Local Trevor Kyle told the Australian Broadcasting Corporation that the first orb was found by a crab fisherman,who was told to ditch his pot by cops.

Kyle initially shrugged it off as a buoy but began to worry when he saw officers flood the beach.
