Also I can't believe I spaced on this, but we are trained by movies to ignore the fact that we are in orbit around the Sun, and you can't just 'drop' things into the Sun.
From the numbers I can find, the delta-v to achieve escape velocity from the Earth is just over half the delta-v needed to crash into the Sun. To "get rid" of something you need a big rocket. To get rid of it forever, the rocket equation means you need a rocket many times bigger to go 90% faster.
