- positive and negative ions are produced from the heat energy of candle flame.
- Then,the positive ions will be pulled towards the negative plate while negative ions will be pulled towards positive plate
-The positive ions is heavier than negative ions
-Hence,a large force is required to pull the heavy positive ions to the negative plate

-the heat energy from candle flame produces positive and negative ions.
-The positive ions which is pulled towards negative plate and the negative ions which is pulled towards positive plate
-The positive ions heavier than the negative ions.
-A large force is required to pull the heavy positive ions to the negative plate.

-when the polystyrene ball touches the negative plate, it receives negative charges.
-So the polystyrene ball is attracted by the positive plate.
-When the polystyrene ball touches the positive plate ,its charges is neutralised and immediately receives positive charges.
-Hence the polystyrene ball is attracted by the negative plate.
-The process is repeated caused the polystyrene ball oscillates continously.

-heat energy from the candle flame produce positive and negative ions
-negative ion is pulled towards the positive plate while positive ion is pulled towards the negative plates
-positive ions have larger mass than negative ions
-more force is needed to pull the positive ions towards the negative plate.

- when the metallic ping pong ball touches the negative charged plate, it receives negative charges and becomes negatively charged

- the negatively charged ping pong ball is attracted to the positive charged plate due to different charges

- when the ping pong ball touches the positively charged plate, the negative charges is transferred to the plate

- the positively charged ping pong ball is attracted to the negative plate

- the process is repeated causing the ball to oscillate.

-When the polystyrene ball touches the negative plate, it will be charged with negative charges.
- so, the polystyrene ball will be attracted to the positive plate.
- when the ball touches with positive plate, its charge will be neutralised and immediately receives positive charge.
Hence, the ball will then attracted to negative plate.
- This process is done repeatedly caused the polystyrene oscillates continuously.
