Meanwhile, BLS take on the Glamour Girls in Ninja Nan's Denture Adventure. This challenge takes place on one of the famous Blast Lab obstacle courses. This time, however, it's known as an 'a salt' course aimed at revealing the incredible power of salt. At the end of the course are two large cylinders filled with water; sitting at the bottom of each are Ninja Nan's dentures. The teams have to use salt to get the dentures to rise - the quickest team to retrieve the teeth wins.
