Standing about 20 inches tall and 10 inches wide, this life-like Human brain is secured in a two gallon heavy duty glass laboratory vessel. The lid is heavy glass and stainless steel. The pump is located inside the steel base for protection where an ample supply of fresh oxygen is sent cascading to the life-sized brain. A 25 watt lamp in the base offers a great visual punch. The brain is of thick latex rubber and suspended via a clear monofilament tether.
