Author description: The tapioca tactile illusion is a variant of the velvet hand illusion that can produce a smooth tactile perception between two hands. This variant is made with a 8-10 mm hole on a piece of cardboard paper or a plastic sheet of 0.3 mm thickness. When an observer sandwiches the slit with two fingers and then moves the fingers back and forth parallel to the slit direction, he/she perceives a smooth tactile texture with a plump feeling like a tapioca pearl.
