Brigid Burton from Edmonton, Canada wanted to keep her daughter's boyfriend, Daniel Gray, busy during the winter months so she asked him to create an igloo. But she didn't want just any igloo, she wanted a rainbow igloo. The year before, Burton filled milk cartons with colored water and froze them to create colorful icy bricks for the job. Gray didn't mind the task too much because he happens to be an engineering student. He also had help from friends and family who spent nearly 150 hours putting together the 500 blocks of the structure. Hopefully other moms will not follow Burton's example.
