Experiment involving changing silk rose from white to red?

My mom told me about an experiment a teacher at her school uses. He dips a white silk rose in something and it changes to red. Then he turns it back to white.
I would love to try this, but I do not have any indicator dyes. Is that what he used? Has anyone heard of this?

Ps- I actually was hoping to try this today…

Phenolphthalein was probably used. It is red/violet at a pH of 9.8 or above and colorless at a pH of 8.2 or below.

Take a look at the list of indicators at the site below to see other possibilities.
