Experiments with Static Electricity 

 from Belts 



SOME interesting and very amusing 

 experiments can be made with static 

 obtained from overhead belts in a machine- 

 shop, the phenomena being due to friction. 



Sending the signal of distress to friends in a distant boat with the use of dots and dashes of the

 to our rescue and helped us back to the 

 shore. — R. H. M., Jr. 



Hold a metal rod to within a few inches 

 of the belt with one hand, while with the

 distinct shock will be felt by both parties. 

 A finger held near the machine will cause a 

 spark, its size depending on the strength of
