Plasma BallPlasma Ball

Why does the glass turn pink when the charge strikes it?

What happens if you place your hand on it? Why?

Page 3: Static Electricity

Try two people touching it.

Page 4: Static Electricity

Predict what will happen if you bring the

Page 5: Static Electricity

Why does this happen?What if you hold the bulb in the

middle?

Page 6: Static Electricity

Why does this happen?Try holding it in different positions.

Page 7: Static Electricity

Take a neon bulb and hold it towards the plasma ball. What happens and

why?

Page 8: Static Electricity

How far away from it can you hold it and get it to light up?

Page 9: Static Electricity

Place the hair/place your hands on top of the Van de Graaff and charge
