This is a demonstration of the ideal gas law. Balloons placed in liquid nitrogen shrink because the decreasing temperature of the gas inside the balloons causes the volume to decrease.

This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.
