Yes. Another technique was to use alcohol rather than water since it has lower surface tension, but that was only workable for smaller models (which were usually enclosed).

I think a model this size full of alcohol would also be quite hazardous for several reasons.

Even if it wasn't a large size, it likely wouldn't be great. During my PhD on sprays, I did some (unpublished) experiments using isopropyl alcohol to reduce the surface tension. The nozzles I used were around 1 mm in diameter as I recall. I did not anticipate that the room would fill up with isopropyl alcohol vapor and (probably) tiny droplets. I wore a mask and maybe left the room while each trial was running. Breathing that likely wasn't great for my lungs.

		You just get drunk from the vapour way faster than it can have a measurable impact on the lungs. (you can actually drink it if it's reasonably pure. it's even less toxic than ethanol, but the hangover is terrible)
