Dictyophorus spumans, the koppie foam grasshopper, is a species of grasshopper in the family Pyrgomorphidae, indigenous to southern Africa. The name "foam grasshopper" derives from the insect's ability to produce a toxic foam from its thoracic glands, using a combination of hemolymph with air from the grasshopper's spiracles. Adult males are typically 4.5 to 5 centimetres (1.8 to 2.0 inches) long, and females typically 5 to 7 centimetres (2.0 to 2.8 inches), but individual grasshoppers can grow up to a length of 8 centimetres (3.1 inches). This grasshopper of the subspecies D. s. spumans was photographed in the Walter Sisulu National Botanical Garden in Roodepoort, South Africa. Photograph credit: Charles J. Sharp

Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist. He is known for his contributions to the design of the modern alternating-current electricity supply system. This photograph, taken in Tesla's laboratory in Colorado Springs in December 1899, supposedly shows him reading in a chair next to his giant "magnifying transmitter" high-voltage generator while the machine produces huge bolts of electricity. The image was created through a double exposure as part of a promotional stunt by the photographer Dickenson V. Alley. The machine's huge sparks were first photographed in the darkened room, then the photographic plate was exposed again with the machine off and Tesla sitting in the chair. In his notes, compiled in Colorado Springs Notes, 1899–1900, Tesla admitted that the photo is false. Photograph credit: Dickenson V. Alley; restored by Bammesk
