son. Rescue Randy has also been referred to as "Ted" (for Bus-Ted, Annihila-Ted, Humilia-Ted, and so on). These were added partly because Buster (even after his redesign) was becoming increasingly difficult to repair, and also because not all myths can be accurately tested with Buster due to his size, weight, and other factors. For instance, Suzy (a child dummy) was used to test the myth that a child could go 360 degrees around a swing set. Being representative of an adult man, Buster would not have properly fit the criteria for the myth. The Simulaids were first introduced in the Killer Brace Position myth, primarily because multiple dummies were needed for testing. At least one Simulaid has been destroyed in the course of subsequent experiments (In the "Point Break" trilogy the Simulaid was destroyed when it hit the ground from 4000 feet). Ted Ted is an extra crash-test dummy used in the show. In addition to this, any full-size human made from ballistics gelatin is usually named Ted, from the last syllable of bus-ted, annihila-ted, exploi-ted. One instance of Ted's use was in the "Train Suction" myth, in which he played the unsuspecting commuter. Deadblow Deadblow, Grant Imahara's battlebot, has been used to aid the MythBusters in various ways, such as measuring vibrations in the ground (for the "Chinese Invasion Alarm" myth) to being a cat decoy (in the "Beat the Guard Dog" myth). Grant temporarily renamed the robot "Blinky" and fitted it with a set of headlights to simulate an oncoming vehicle for the "Driving in the Dark" myth. Sparky Sparky was a robot used multiple times on the show. In the "Gunpowder Keg" myth, Jamie took the motor and wheels from an electric wheelchair and fitted it with a metal hood for protection, a remote control, and a stand for a keg of gunpowder. The MythBusters drilled a hole in the keg and lit the ensuing trail of gunpowder on fire to see if the fire would travel up the falling stream of gunpowder and explode the keg. After many trials, the myth was called plausible, and Sparky survived. Sparky was used again in both the "Hot Bullets" and the "Campfire Chaos" myths to drop bullets of various caliber as well as aerosol cans into a campfire to see if they could cause serious injury or death. Sparky was not damaged, but it was determined that both bullets
