I would like to know if there is a safer model to demonstrate a volcanic eruption other than the ammonium dichromate reaction which although fabulously exciting is deemed carcinogenic. Is there another safer chemical that can be substituted? I DO NOT want the baking soda and vinegar model!!

The demo will have to involve some sort of violent explosion -- and that means significant hazard potential from uncontrolled fire to the generation of respirable dust. I would suggest that you consider video tapes and/or DVD's of actual eruptions. Many are available on the Internet at a reasonable price. Some suggestions for where to start are:'s
