What Happens When Thermite Pyrotechnic Powder Is Ignited Atop a Block of Dry Ice

YouTube science experiment channel Carsandwater (see previously) wanted to see what would happen when a pile of thermite was ignited atop a block of dry ice. The results are initially spectacular, with the pyrotechnic powder creating a bright light show, before combining into a glowing mass with the sub-zero carbon dioxide block.
