Erector Set
In the late 1980s, with an Erector Set, various old toys, and bits of jewelry, Dr. Kevorkian jury-rigged a machine he called the Thanatron (later renamed to the Mercitron.) Three bottles were suspended from a rickety beam, one filled with a saline solution to open a patient's veins, another with barbiturates for sedation, and a third with potassium chloride to stop the heart. After the Doctor connected the patient to an IV, he or she would pull a chain on the device to start the lethal medications flowing. He called it his "Rube Goldberg suicide device."
