Lembrei-me de trazer para aqui uma ideia amplamente discutida nos fóruns geocaching:
- Qual a cache NÃO APROVÁVEL que gostariam de poder colocar?

aqui vão alguns exemplos:
- How about a night cache in an ammo can, rigged to set off a flashbulb or strobe when you open it?
You´d find the cache and have to wait 20 minutes to be able to see well enough to sign the logbook!
- What about a fake tombstone in a cemetery?
- a micro diguised as sand hidden in the sahara.
- Tennis Ball Canon Cache
To complete this cache you must bring a can of hair spray and a lighter.
Coord´s will take you to a vertically mounted pipe, capped on the bottom. Small cache sits inside the pipe, near the bottom, on top of a spacer raising the cache above the bottom (area henceforth to be known as the combustion chamber). Note small hole drilled in the side of the combustion chamber.
To obtain the cache, spray a 2-3 second burst of hair spray into the hole in the combustion chamber. Immediately hold lighter to the hole.
After retreiving the cache:
Clean out your shorts
Sign the log
Place cache back in the pipe
!!!CAUTION!!! Do not place any body part in front of the large opening on the top or the small opening in the combustion chamber during the ignition process. !!!CAUTION!!!
