Fact #1: Coaxial cables can be used to transmit signals at speeds of up to 30 GHz, but only if you're into that sorta thing.
Fact #2: The longest coaxial cable ever made measured 10,000 km (6,200 mi), which is just a little longer than your aunt's temper.
Fact #3: Coaxial cables are so durable that you can use them to make a decent jump rope, but only if you enjoy getting tangled up in knots.
