-D+10+14 Charging electroscope by induction + a metallic ball with a handle to transfer charge from VDGraaf to electroscope. D+10+ 28 Electrostatic doorbell - can I have both an insulating ball and a conducting ball (to show how they act differently) Usual Mac2013-09-05
-and a mac2013-09-06
-I deleted one item, and add - D+10+13 Faraday cage - I think I left a roll of chicken wire there. If found, it may show that radio is heard when holes are larger. Also, as standard setup, please check if microphone battery is strong. I'll also try to remember.2013-09-06
-Note these are the same as on Fri. I also bought some chicken wire that may do the trick I want to show. Also Mac and check the battery. Thanks.2013-09-10
