Who knew that a ping pong ball would be worth so much

Basically on Friday 10, 2010 we got in to group of fours and experimented with $600 ping pong balls or so Mr.Chung says.
Question and Answers

1. Can you make the energy ball work?
    A: Yes
    What did think makes the ball hum and flash.
    A: When placing two fingers on the metal strips the ball will hum and flash?

2. Why do you have to touch both metal strip for the ball to work?
    A: you need to connect the strips of medal to getter for the charge to pass through your fingers.

3. Will the ball light up if you connect it with any other materials
    A: Only if you use materials that can conduct electricity.

4. What material can be used?
    A: -copper
         -lead
         -skin tissues
         - Basically any conductible materials.

5. Why does this not work on certain individuals?
    A: If the person was wear a insulator like material such as rubber or leather glove.

6. Can you make the energy ball work with 5-6 individuals in your group? Will it work with the entire class?
    Yes and yes, as long as all individuals are connected.

7. What kind of a circuit can you form with one energy ball?

   A: Series circuit

8. Given two balls (combine two groups): can you create a circuit where both balls light up?

   A:Yes, by forming a parallel circuit. 

9. What do you think will happen if one person lets go of the other person’s hand and why?

    A: The energy will stop working because there will be a gap in the connector. Thus there won't be a current of charge passing through the load ( red light bulb and the speakers)

10. Does it matter who lets go?

      A: no it does not matter who let go as long as the a missing link the energy ball(s) will not work.

11. Can you create a circuit where only one ball lights (both balls must be included in the circuit)?

      A: Yes, if we use a parallel circuit and have a switch like the image to  the right

12. What is the minimum number of people required to complete this?

      A: 3 people.

Parallel or Series

A circuit made of connections in sequence is known as a series circuit where as parallel circuits are connected completely parallel to one another.
