The most famous experiment of Benjamin Franklin is the “flying a kite in storm to see if lighting is elecricity” one (that is not confirmed to has been done by him or with an actual kite; the discussion is still going on). He is also known for naming the positive and negative electricity, finding if conduction is changing due to temperature and so on. He was also experimenting with evaporation. Not only that, Franklin managed to chart the Gulf Stream, noticed storms could travel in directions other than that of the prevailing wind and came up with many other ideas how to help sailors.
I won’t tell you what type is Froakle supposed to be, because no one knows it yet, but I really hope it’s Water/Electric.
