Another way to fight depression

When I was a student (first time) and spent time in a lab at lab works of achieving the complex soils or kinda (it was formulas something like N₂[K₂SOH])- to create N₂0 - the laughing gas. I don't remember the formulas and the reagents, but there were some redox reactions with issues of light gases. And the most laughable situation was that creating that gas was more laughable, than the gas itself =)
