In chemical terms it is the reaction between Aluminum foil & Sodium hydroxide ( solution).
Sometimes the reaction is written like this:
2NaOH+ Al= Na2AlO2 + H2
But in reality there is not an oxide formed but an hydroxide complex named : hydrated Sodium Aluminate .
2Al + 2Na+ + 2OH- + 6H2O ==> 3H2 ( gas) + 2(NaAl(OH)4
