- Project Question: Pop Goes The Geyser. When the flask at the bottom is full and the water in the glass tube comes down , I cant keep it from leaking unless I hold the rubber stopper with my hands. There is too much pressure. Even though I use plumbers putty, I still have leaks onto the burner. Any suggestions, like some sort of clamp?

Pop Goes The Geyser
Should the waterlevel in the flask below be full or have some air space left in the flask, for an eruption

Re: Pop Goes The Geyser

Re: Pop Goes The Geyser
Hi:
Please remember that these forums are staffed by volunteers, and we do not have access to any more information about the experiment than you do. I'm going to make some guesses here that may help with your questions.
You need a good seal on your stopper. Was the plumber's putty soft when you put it on the stopper? If it's dried out, it won't seal well. If the putty is not working, try redoing it. If the stopper is pushing out of the flask anyway, instead of using your hands, can you use duct tape to hold it in?
The water level in the flask should not be full. There needs to be an air gap. Also, did you only push the glass rod in to the bottom of the stopper? If you're pushed the rod in farther, you will have problems. That's what I suspect when I see your comment:

. Also, heat the water up slowly until you get results, and try to maintain an even temperature.I get small gurgles with the water hot ,but a continuous eruption with the water boiling
