Go to Sweetopia's website and search for "Getting Rid of Air Bubbles". She has the link for the dental vibrator I bought from Amazon. Make sure you keep the packing foam that is used to pack the vibrator in the box. I use it to hold my bowls or bottles with icing. Otherwise they fall off from the vibrations. I also dry my cookies with a fan as Sweet Sugarbelle suggests in her Blog site. I have read many blogs about air bubbles, the one tip everyone talks about is consistency, consistency. I am also going to try Julia's tip of drying cookies with a heat gun for problems with craters. Just saw her YouTube on how to ice a cookie and that tip was in there.
