Fill a syringe that is made for glue with wallpaper adhesive.
Cut a small slit into the wallpaper bubble using a razor blade. The slit should only be big enough to fit the tip of the syringe in it.
Squirt a small amount of adhesive into the slit. For larger air bubbles, you will need to use more adhesive.
Flatten the bubble by rolling a seam roller over it.
Wipe off any adhesive that leaks out of the slit with a damp paper towel.
