Frost the Science Guy Organizer
Isaac is the second scientist Frost gathers. He is conducting a drop test with an Apple iPhone when Frost barges in, causing him to drop the phone prematurely. When Pierre Curie opens the pickle jar he celebrates.

Trivia

 * Isaac's drop test with an Apple product is a reference how Isaac first thought about gravity after seeing an apple fall from a tree.
