I'm glad to hear someone else doesn't like that analogy ! It falls apart so
fast ...
"If electricity in a wire is like water in a pipe, then why do pipes get
cold but wires get hot ?"
"Is there hot and cold electricity ?"
"Why can't I pour out the electricity from a wire like I can water from a
pipe ?"
Or my favorite, "How do I hook a bucket to my electrical outlet ?"
In my (very limited) experience, it's better to describe electricity as
"magic" and let the students tell you why it's not magic.
