Topic of investigation

:  "Bending" water with  static electricity

A	Observations made
	The stream of water will 'bend' towards the balloon when the balloon charged with static electricity is brought near the stream of water.
B	Research Question
	Does the distance between the stream of water and the balloon affect the degree of ”bend” of the water?
C	Hypothesis statement
	The closer the balloon is to the stream of water, the larger the degree of ‘bend’ of the water.
D	A short summary of research done on the area of investigation
	Short summary of research done on the area of investigation: - Static electricity is developed and accumulated when two objects are rubbed against one another - When they are rubbed together, electrons jump from one object to the other. - Object that loses electrons become positively charged - Object that gains electrons become negatively charged - The balloon and your hair would both acquire opposite charges when rubbed together, causing the charge of the balloon to attract the molecules of water in stream. -  This can be done because the molecules in the stream can be moved easily, allowing the stream to bend towards the balloon - Static electricity works better at a place with low humidity as at places with high humidity, the surface of objects are coated with a thin layer of water, which prevents electrons from jumping between the objects
