Grape juice?

Chem lab involving Potassium Permanganate, tomorrow. 5S1 Chemistry Class 2007, remembered.

I don't remember the exact dates, nor the exact conversations, but I do remember the highlights. Correct me if I'm wrong!

Basically, Potassium Permanganate (apparently poisonous) is of the same colour as grape juice.

Procedure:
1.Clean test tube. Fill with grape juice.
2.Ask the teacher of the consequences of consumption of this chemical.
3.Do not give her enough time to answer.
4.Swallow the contents of test tube of purple liquid.
5.Laugh.

Observation:
Her jaw dropped. We laughed.
