Thats simple to fix 
You could go to a glass shop to brake the glass where the metal cover is then join a new tube onto it and have the join part where the cover is
you could also just buy some plastic tubing if the bubbles don't work as the bubbles are actually liquid which is heated and forms bubbles inside the tub it's not actually air (kinda like a lavalamp but it forms air inside the oil not wax)
you should think about using plastic or other types of material to cover the light tubes.
