Experiments

This morning I wondered what would happen if I watered my plants with coffee, to “wake them up,” and then I wondered if anyone still conducts experiments like that at home anymore. Old-school, science project-style experiments (plant with coffee vs. plant with just water). Like: Which ___ is better at ____? Or something like that. Do you? Or has Google solved those little problems?

And it looks like you definitely can water plants with coffee. Some of them, at least.
