A display representing a tree, such as a Christmas tree, has a trunk made of a hollow tube and held by a base in substantially vertical position. A liquid, such as water, is placed in the tube and an air supply in or near the bottom of the tube generates bubbles that rise through the tube. The tube and bubbles therein are preferably illuminated to add to the effectiveness of the display. Branches are secured to the trunk tube and extend outwardly therefrom to provide tree foliage and give the display the appearance of a tree or support foliage, such as in the form of a garland, which provides the tree foliage and gives the display the appearance of a tree.
