Demonstration with Iodine and a product of paraffin on programme

On BBC Breakfast TV this week there was an experiment that I didn't see but was reported to me by a non-scientist involving the reaction of a powder with a what I presume was an alkene that produced Iodine as a vapour. I am a technician in a secondary school and would like to try this as it was apparently quite impressive. Can you tell me what it was?

The item may have been a promo for the BBC TV science series "bang goes the theory" ...

Rather more likely to have been the reaction of iodine with turpentine.

It was probably iodine and turpentine. You pile iodine crystals or iodine powder, if you prefer, onto a lab table and smother it with liquid turpentine, which causes an impressive purple smoke cloud to billow into the classroom. The smoke stings a little so it is best done under a fume hood.
