Kimberly Santleben-Stiteler tells ABC13 she used 20 pounds of the explosive target material Tannerite for the blast, which could be heard for miles Saturday night in Medina County on her family's farm, west of San Antonio.
Santleben-Stiteler's divorce was finalized the day before. She says she had originally just wanted to burn the dress. Her dad had the idea to blow it up.
It took her just one shot from a rifle to set the explosives off 200 yards away.
About 40 friends and family were there to cheer Santleben-Stiteler on.
