The glue dribbles out after you stop squeezing because of an air bubble inside the tube. You compress the air slightly when you squeeze... then when you release your hand pressure, the compressed air inside expands and pushes the glue out. This " bubble is normally pretty large - occupying 1/2 the tube sometimes on the little tiny tubes. To stop the glue from running out, take the tube of glue in your hand with the tip pointing up your arm and give it a couple of good swings while keeping your arm straight - this will cause the glue to go to the bottom of the tube and the air to rise to the top. Uncap the tube, purge the air, roll up the extra foil and you' re ready to go.
