How wonderful is this?

This balloon tank was part of a 2007 exhibition put on by Inges Idee, a group of 4 German artists who create various public art projects. [via]

The balloon tank is made by German artist Hans Hemmert. At the end of the exhibition, the balloons were popped and the balloon tank was reduced to a pile of stretchy, colorful goodness.
