top surface of the Trinitite layer was

still heated somewhat by the fireball and thus developed a smooth surface." "We calculated an average fireball temperature of 8,430 Kelvin," they reported. That's 14,710 degrees Fahrenheit. The new theory explains the tiny spheres of glas and beneficial experience for the students. Specific programs include:

s found onsite as

• drops that cooled and hardened enough to keep their shape when they hit the ground. It also explains why there was Trinitite found
• on top of the outer edges of the asphalt used around the 100-foot tower and on some objects left in the ground zero area. Soldie
