This also works quite well using the Wilton Doll Cake pan...Less carving..... I use the dry ice and pour jello water over it. The Jello first smokes and then as it sets it turns into bubbles that slide down the cake . No harm to the fondant. .http://www.cakecentral.com/gallery/i/3266578/fantasy-island-volcano-cake-really-works
Thank you for the recommendation. It is a very creative and fresh idea. I hope to do something like this but because of my new gaming project at https://wageringadvisors.co.uk/best-low-wagering-casinos/ I feel like I don't have time for hobbies. But gladly I love my job! Anyway, I am grateful for sharing!
