I guess if you mean "money is a small amount of liquid" then the analogy is fair? Otherwise the terms are very different -- handouts are not called "trickle down" in the US. The principle is not the same, it is literally the opposite.
"Trickle down" in the US is a term used to disparage the idea that a strong economy benefits the poor even in the absence of explicit redistribution.
