What should I do?

On August 20th, Hunter S Thompson's ashes where blasted out of a cannon as fireworks. How cool, I thought to myself. I want to do something like that when I die. But what will I do? Here are my options so far.:

1. Have may ashes turned in to a concrete block and dropped in the ocean to become part of a coral reef
2. Have my ashes turned in to a gem stone and put in to a ring for my loved ones.
   
3. Have a small amount of my remains blasted in to space as part of a satellite.
   
4. Or I could just be buried normally and have one of these on my grave stone

Ahh the decisions. Well I think I will have plenty of time to decided what I want to do. Although the ring thing is kinda freaky. I may avoid that. That last option I may have too much fun with.
