Speaking in Tongues
For an idea of speaking in tongues, we purchased a card game called Bible Mad Gab very inexpensively at our local Christian book store. It consists of words on a card which when read doesn't seem to make sense but actually lists a bible sentence or phrase when the kids figure it out. It sounds like they are speaking in tongues but they are actually saying something of importance. It was a lot of fun and brought the point across really well.
