A three-minute minutephysics video on the orbital mechanics of why crashing into the Sun takes far more energy than leaving the solar system.

Scott Manley uses a realistically scaled Kerbal Space Program setup to show why dropping something into the Sun is far harder than it sounds. It demonstrates the need to cancel orbital velocity.
