Create a simple black hole and experiment with gravitational pull.
A black hole is an invisible entity in space with a gravity pull so strong that light cannot escape. we will create a simple black hole and try out different rolling objects to see if they differ with the holes gravitational pull.
you will need: piece of paper, scissors, tape, a cup and different small round objects. i.e. ping pong, ball bearing, small bouncy ball, beads or marble.
