The Color-Changing Martini
Intro: The Color-Changing Martini
(For the non-alcoholic, dry ice-free version, see the color-changing sports drink)
STEP 1: Ingredients
Gin (or vodka, for a vodka martini) ~ Vermouth ~ Dry Ice ~ Baking Soda ~ Red Cabbage
STEP 2: Red #$@%! Cabbage?
To get the indicator, chop up a cabbage leaf, put it in a bowl with some water, and microwave until it's boiling (or just add boiling water and allow to steep). A purple pigment will stain the water.
STEP 3: Build
STEP 4: Present
Give the recipient the drink. Tell them to watch closely, then add a chunk of dry ice. It will sink to the bottom of the drink, and bubble away happily, slowly cooling the drink. It will also neutralise the baking soda and change the colour of the martini. See it in action in the video above.
(that's not me saying "wow, that's wicked" by the way. This drink was mostly made as a way of keeping three small children entertained while their mother was out Christmas shopping. They liked the look of the cocktail, but thought the mocktail version was "really disgusting". I did warn them that it was just salty, cabbage-flavoured water...)
It should go without saying, but wait for the dry ice to disappear before trying to drink the cocktail. You do NOT want to swallow any dry ice!
STEP 5: Taste
I didn't initially regard this drink as spooky in any way, so was surprised to see it appear on various "Creepy Halloween Foods" lists (dabbled, neatorama, mentalfloss, etc). The lists were great and well worth checking out (they included some really effective eyeball recipes - see here for my version).

Very fun, thanks, sorry I am late to join the question party but I will try none the less;
Could I make ice cubes out of carbonated water and use this to replace the dry ice?
It appears all you need is the indicator liquid-mixed with soda, then co2 to change the acidity,..right?....or replace the co2 cubes with frozen acidic liquid,...maybe pineapple juice?

I think it is unlikely that you will preserve much CO2 in the ice cube. But yes, adding acid of pretty much any source will make it change color, see https://www.instructables.com/id/The-Color-Changing...
I haven't tried it but you might even be able to just blow through a straw and do it with the CO2 in your breath.

This is a great drink idea but was wondering if you had any ideas of changing the drink color to the color blue? Is this even possible considering blue is a primary color.
I'm having a gender reveal party and would love to have a drink that the end color turns blue...any suggestions?
makendo 8 years ago
Yes, absolutely. Just start it off purple (you probably won't have to do anything to it - it's naturally purple - but if it is blue, add a *tiny* amount of acid). Add base (a weak baking soda solution) to make it go blue (add citric acid if you decide you want red, see https://www.instructables.com/id/The-Color-Changing-Sports-Drink-Mocktail/ for more details). Just make sure you experiment ahead of time, the quantities and strengths of what you add are crucial. Have fun!
