I wonder what would happen if you got a small polyethylene (Nalgene) 
bottle, poked holes in it, filled it with marble chips or crushed coral, 
and dropped it into a larger container with a dilute hydrochloric acid 
solution? The number and size of the holes along with the strength of 
the solution would dictate the rate of the reaction. I would wear some 
good lab gloves when working with the setup though.
