In this photo provided by Positivedialogue Communications on Tuesday, April 2, 2013, Matt Silver-Vallance poses with balloons against a backdrop of Table Mountain, in Cape Town, South Africa, Sunday, March 31, 2013. Wind speed and direction permitting, Silver-Vallance will strap himself to 200 big balloons filled with helium, float off the island beneath a bulging latex column of color, and drift to the shores of Cape Town for a charitable cause.
