Most expensive thing (for consumption) you've spent money on?

^ obviously a nana point of view

I just bought a $12k USD modular synthesizer. ^^

Blake just messed his new jeans.

Some guy did it from space. 30k feet is a piece of cake. IF you are worried about accuracy then just tape a large magnet at the top of Mt Everest and sky dive in a metal suit. Sounds pretty simple to me.
