Are you using 30% hydrogen peroxide from a chemical supply (like Flinn)? A long narrow container, like a graduated cylinder also helps. I use potassium iodide and typically get a nice fountain followed by oozing.

Hi Chris, Sounds like an interesting project! A few years ago I took one of the edX MOOC courses called " HarvardX: SPU27.1x Science & Cooking: From Haute Cuisine to Soft Matter Science " and it had a fair amount of chemistry included.

4 Great Source for Ideas
This book just looked like so much fun that I had to purchase it and I wasn't disappointed. It includes over 50 different gadgets and gizmos, as they call them, organized around 7 physical concepts. Each one comes with questions that students should think about and each set includes the Next Generation Science Standards that that activity deals with. All the of the gadgets are readily available from a scientific supply catalog or Amazon at a reasonable cost. This book will motivate you to expand and use your science toy collection!

The authors give a good argument for the importance of preassessment in the identification of misconceptions among students. Their examples of effective preassessment questions are good ones. Good read.
