The bubble table provides hours of scientific explorational fun. A bubble table should hold liquid bubble solution in and not leak on the floor. This acrylic box manufactured as a cover for MOMA art displays, does exactly that. It holds a gallon of water as a thin layer of water. A Hula hoop with twill wrapped around it is hoisted by a single pulley that hangs from the ceiling.
The goal is to pull up on the hoop slowly so that either a large bubble forms on the table or a film forms across the hoop.
Observe the the image of the sun in the reflection of the bubble.
With a thin film on the hoop, reflections can be cast onto the ceiling.
Here the Film is about to separate from the bubble below.
