I also implore you to research everything on that list and its origin or credit for widespread use, starting with the one you critiqued: "The ice cream float was invented by Robert M. Green in Philadelphia, Pennsylvania, in 1874 during the Franklin Institute's semicentennial celebration. The traditional story is that, on a particularly hot day, Green ran out of ice for the flavored drinks he was selling and instead used vanilla ice cream from a neighboring vendor, inventing a new drink.[3]" Best of luck to you!
