Let Vader help you turn appliances on and off with the ThinkGeek Star Wars Darth Vader Clapper. Unlike using the force, this device controls appliances in response to clapping. To use the Star Wars Darth Vader Clapper, start by plugging it into an electrical outlet. Then plug the appliance you want to control into the base of Darth Vader’s helmet. If you clap twice, the outlet will turn whatever’s plugged in on or off. In addition, Vader has two sayings to accompany the actions, including “You underestimate the power of the Dark Side and “The Force is strong with this one”. The officially licensed Stars Wars merchandise uses the retro-futuristic technology of the 80s with the added bonus of Vader. Made from flame retardant plastic, the Star Wars Darth Vader Clapper works with appliances that don’t have a heating element.
