You can dilute the lye/water solution with more water
and very precisely control the rate at which it dissolves
aluminum.
I used the lye/aluminum reaction a lot as a boy to make
hydrogen to fill balloons.
The hydrogen gas comes off very hot and must be ran through
a coil of tubing submersed in icewater.
But, if diluted enough, you can control it to react
at any speed or heat that you choose.
