Experimentation

A website entitled the T.W.I.N.K.I.E.S. Project[6] was launched in 2000 by Christopher Scott Gouge and Todd William Stadler.[7] This site chronicles a series of regimented scientific experiments testing, amongst others, the insulative, electrically resistive, radioactive, and gravitational properties of the "Standard Twinkie".
