@snopes. “Cell Phone Recharging Electrocution.” Snopes. Snopes, 2014. Web. 15 Nov. 2016.
This article discusses the possibility of cell phones causing electric shock. The article cites several occasions of explosions occurring but only with poorly made foreign batteries. It also explains that electric shock is extremely unlikely and the battery will most likely just melt or explode.
This is another straightforward article that will not be winning any creativity awards. It does prove its point quite thoroughly by displaying the claim followed by a extensive counterargument.
This source will be useful in showing how public fears and suspicions can be used to manipulate fact into fiction. There is a large difference between explosion and electrocution and a even larger difference in foreign batteries and regulated batteries. Displaying this should be beneficial to the idea that urban legends are only legends.
