We have never had much luck doing the Diet coke and Menthos. Do you use the menthos straight from the pack or do you crush them a little to get more surface area. I read somewhere that the Australian menthos had a smoother surface so didn't work as well.

Using my little contraption I made last week I got the fountain as high as a house roof in my trial before doing it for the kids. But when I did it for the kids the mentos got stuck in the tube and blocked it meaning a fine spray came out instead :( most disappointing for me but still exciting for the kids (they didn't know what was supposed to happen). I am going to do it again tomorrow without my contraption (which I made intending to get a higher fountain than you'd get just through the opening of the bottle) and also do the elephant's toothpaste. Hopefully I'll get some photos and post them here for you :)

Another tip for the heated up diet coke is to open the lid VERY SLOWLY!
