The forerunner of the aerosol can was invented by Erik Rotheim of Norway. On November 23, 1927, Rotheim patented a can with a valve and propellant systems - it could hold and dispense liquids. The first aerosol can (a can than contains a propellant [a liquefied gas like flurocarbon] and has a spray nozzle) was invented in 1944 by Lyle David Goodloe and W.N. Sullivan. They were working for the U.S. Department of Agriculture and were trying to find a way to spray and kill malaria carrying mosquitos during World War II for the soldiers overseas. The "clog-free" spray valve was invented by Robert H. Abplanal in 1953. The first spray paint was invented by Edward H. Seymour in 1949. Seymour's wife Bonnie had given him the idea of an aerosol applicator for paint. The first spray paint he developed was aluminum colored. Seymour formed the company, Seymour of Sycamore, Inc. of Chicago, USA, which is still in operation. Hundreds of articles that support animal classification, behavior, and habitat lessons!

The CW recently released another sneak peak of this season's first episode, "Out of Time" which features the team trying to make a difficult decision - either save New York City from being destroyed during World War II or go back in time to save the world from being taken over by Nazi forces. In the clip Nazi Germany has won World War II, but because the Waverider is in the temporal zone the team hasn't been affected by the changes in the timeline yet.
It's pretty clear how Mick feels about the situation when he says, "I'd rather die than speak German." Professor Stien chimes in with his usual voice of reason explaning that they are "history's last line of defense," now that the time lords are gone. The second season of DC's Legends of Tomorrow sees the crew of the Waverider facing off against Damien Darhk, The Reverse-Flash, Malcolm Merlyn, and Captain Cold -- The Legion of Doom -- while teaming up with the Justice Society in the form of Obsidian, Stargirl, Doctor Mid-Nite, Citizen Steel, Vixen, and Hourman. Check out the official synopsis for the season premiere of DC's Legend of Tomorrow below: LOST AND FOUND — GUEST STARRING STEPHEN AMELL — After the defeat of the immortal villain Vandal Savage and the exposure of the corrupt Time Masters, a new threat emerges. Dr. Nate Heywood (Nick Zano), an unconventional and charming historian, is thrust into the action. After making a shocking discovery, Nate seeks out Oliver Queen (guest star Stephen Amell) for help in finding the scattered Legends.
Once reunited, the Legends continue their new mission to protect the timeline from temporal aberrations - unusual changes to history that spawn potentially catastrophic consequences. Their first stop is 1942, to protect Albert Einstein from being kidnapped before the Nazis destroy New York City with a nuclear bomb. Meanwhile, Ray (Brandon Routh) notices that Sara (Caity Lotz) has a mission of her own, which leads them both to face her nemesis, Damien Darhk (guest star Neal McDonough). Victor Garber, Arthur Darvill, Dominic Purcell and Franz Drameh also star.
