Power from a capacitor
The most important issues that you will face regarding the capacitor with trying to discharge so quickly are probably the equivalent series resistance and the inductance of the leads.  Both of these can be mitigated by using more capacitors in parallel instead of a single large capacitor.  Both resistance and inductance in parallel reduce in this configuration.

There are other non-capacitor related issues such as the switch and other inductances in the system as well as how to control the current.  In any case, take care with your experiments.
