MATERIAL

McVeigh and Nichols purchased or stole the materials they needed to manufacture the bomb, which they stored in rented sheds. In August 1994, McVeigh obtained nine Kinestiks from gun collector Roger E. Moore, and ignited the devices with Nichols outside Nichols' home in Herington, Kansas.[34][35] On September 30, 1994, Nichols bought forty 50-pound (23 kg) bags of ammonium nitrate from Mid-Kansas Coop in McPherson, Kansas, this would be enough to fertilize 4.25 acres of farmland at a rate of 160 pounds of nitrogen per acre; an amount commonly used for corn {2000 pounds of AN divided by (160 lb/acre divided by 0.34 lb N/lb AN) equals 4.25 acres}. Nichols bought an additional 50-pound (23 kg) bag on October 18, 1994.[23] McVeigh approached Fortier and asked him to assist with the bombing project, but he refused.
