354. Bright Idea: the Shockball June 20, 2007Posted by Matt Fleming, PsyD in Plaything, Product.
Play catch (or more specifically, Hot Potato) with the Shockball, which emits a shock at random intervals. Rubber-lined to protect it from the inevitable drops to the floor, this plaything sounds like a scream.
