Last night I experimented with glycerin, putting it in water to get the 'heat wave' look that results from a difference in refractive indexes. I forgot that glycerin is miscible in water, and after a little bit of agitation it all mixed into solution and the effect couldn't be seen anymore.
So I tried putting it in 95% ethyl alcohol. It worked for a time, possibly taking more agitation to mix into solution, but it too completely disappeared.
Is there anyway to prevent the mixing? What can I put the glycerin in that will still result in the look I'm looking for? I tried mineral oil, but the glycerin formed into globules.
I'm doing the video shoot tomorrow, so if there's an answer to my question, I really need it by then.
Thank you.
