So I've read a couple different places where couples will pour two different chemical compounds into a glass vase or large beaker or something for the unity ritual. In one example, both poured two clear liquids -- that I'm sure the ceremony witnesses thought was water -- and a reaction took place where it immediately turned pink. There was delighted gasping. I love this idea, in part because it is more interesting that watching people light a candle. You can also get geeky with the symbolism. The two compounds that were once separate are gone, and now have formed a new compound. You could also go at it from the angle that some molecules that come into contact don't interact, and other's do. (I don't take credit for any of this, I found it on the internets).
Does anyone happen to know what these two compounds are? Both clear liquid that look like water, turns pink when combined...
Another version was a couple who did the good old "baking soda volcano." But they did it with two small beakers, one colored blue, the other red, and poured it into a large beaker so nothing overflowed. The resulting color, once the foam settled, was purple, which was their wedding color.
Anyway, just thought this was really interesting, especially for a couple of sciency geeks like my FH and I. Anyone else heard of this, or know of other examples?
A chemistry unity ritual is neck-and-neck with a tree-planting (which we would donate to a local arboretum that is very sentimental to us) right now, so we'll see...
