Breath Hold Challenge - Mandy-Rae Cruikshank and Jessica Wilson will face off in this Ripley's Challenge to see who can hold her breath underwater the longest.

Caffeinated Soap - Shower shock soap provides one cup of coffee per shower.

To achieve this ""conehead"" effect, heads are bound with a soft bandage and woven basket for approximately six months.
