Like an airstone? You must have overloaded on sugar or yeast...

Try this method:

Fill sugar to about 1cm from the bottom of the bottle.
Fill with water to 3/4 of the bottle.
Pour just enough yeast so that the surface of the water top is just thinly covered by a layer of yeast.

control co2 generation rate by controlling the amount of yeast.
usually 1/4 teaspoon for 1.5l coke bottle will do.
you can try using a valve to 'regulate' the co2 flow rate. but there are people who had burst coke bottle. do this at your own risk.
