Why is the LC Oscillator Circuit Called a TANK Circuit?

Why the LC oscillator ckt. is also known as a TANK ckt.?

I just found this on Wikipedia:

The charge flows back and forth between the plates of the capacitor, through the inductor. The energy oscillates back and forth between the capacitor and the inductor until (if not replenished by power from an external circuit) internal resistance makes the oscillations die out. Its action, known mathematically as a harmonic oscillator, is similar to a pendulum swinging back and forth, or water sloshing back and forth in a tank. For this reason the circuit is also called a tank circuit.

I also knew this but i was looking for different answer .
