science fair

For the fifth year, the Promethean Society has presented the Fair of Mad Science at TeslaCon VI, where builders display all manner of working gadgets and non-working props.

And for the fifth year, I continue to be amazed by the entries. People submit all manner of props: rocket packs, weapons, detectors, time machines, breathing apparatus, scientific kits, gauntlets, communicators, vehicles and more created from a vast array of materials.
