VEGGIE MAGIC Wall Panel, Made in USA

Liquid crystals within the panel are sensitive to heat, and change to bright colors with warm hands, then fade back to black. AGES: 1 - 99 yr. 15"w x 22"h x 1"d / 8 lbs Optimal performance temperature is between 72 - 77 The Heat Sensitive Panel is directly related to room temperature. Mount out of direct sunlight or on an inside wall where temperature variation won't affect its performance. Avoid mounting locations near heating or air conditioning ducts. The Wall Toy Panel contains a temperature sensitive material behind a tough, abrasion-resistant film. When this surface is touched, it responds to the person's body heat by changing temperature. If the surface seems to respond sluggishly, the ambient temperature may be too cold. If the surface is red, green or blue when not in use, ambient temperature is too warm. It is designed and manufactured for use in healthcare facilities, where issues of infection control are most stringent. They are made with commercial-grade materials and should be included in the same cleaning protocols as furniture and other high-contact surfaces. Frequent cleaning with most commercial disinfectant solutions will not damage or diminish the product finishes; but the use of ammonia on acrylic may cause cloudiness on mirror or heat sensitive surfaces. Two year manufacturer's warranty, made in the USA!
