Drain opener (foaming). This is sodium hydroxide-based drain opener with a twist. See the little shavings? Those are probably either magnesium or aluminum, which will generate hydrogen gas when the sodium hydroxide is dissolved in water, creating a foaming action. At least, I think that's the idea.
