Chemistry, ground powder on the table:
-
Umbrella opening
-
Knocking, The noise of the elevator
-
Air bubble film, popping bubbles
-
Hammering on construction debris
-
Robot heartbeat
-
Item thrown in the mud
-
Bagging in the bag
-
Digital beep
-
Soldiers pass by
-
The receptionist trolley passes by
-
Flag flaps in the wind on a ship
-
The metal gates of the grill open, close
