 Soucek prepared for his 1984 Niagara Falls stunt by researching previous attempts, by sending unmanned barrels over the falls to test the currents, and by dropping his barrel off the Niagara Escarpment in Hamilton to test its shock absorbence.Soucek's custom-made barrel was nine feet long and five feet in diameter.It was bright red and bore the words, "Last of the Niagara Daredevils - 1984" and "It's not whether you fail or triumph, it's that you keep your word... and at least try!"
