Try adding ice in your vase to make the smoke a little lighter. They also sale special ice adapters as seen here http://www.socialsmoke.com/item--Ice-Bowl-...s--ICEBOWL.html for the same effect. I think its better because it wont melt in your vase and just add more water, plus it doesn't melt as fast. It taste a little cleaner to me, enhances the flavor, and it may last longer..but thats just my opinion. Try it!! :)
