Chemical magic

If you need to run an open evening and showcase your department it´s good to have a selection of experiments and demos that will leave the audience speechless. I have already discussed the classic ammonium dichromate volcano (click here) and today I would like to share some chemical magic. This simple to set up experiment when paired up with a bit of acting can easily surprise your audience as you turn water into wine:

Then wine into water:

and lastly water into milk:

I tested it in beakers but for your "official" demo I suggest following the instructions and use wine glasses and a glass milk bottle.

If not used as a demo, you could use it in your lessons to discuss phenolphthalein as a narrow range indicator. Furthermore, it could be used in precipitation reactions lesson.

I wish you great lessons!
