A great looking graphic diagram of a Viper head is featured on this double wall 20 oz stainless steel thermal tumbler that holds hot or cold beverages. The copper vacuum insulation helps retain idea beverage temperature and freshness. It has a clear acrylic push-on swivel lid that creates a tight seal to prevent leaks and spills. Museum logo at base of design.
Your body is glowing right now. But it's glowing in a color you can't see - infrared. Warm objects radiate infrared light. Snakes that can see infrared light have an advantage when hunting warm-blooded prey: seeing infrared lets them spot birds and small mammals in the dark or in hiding. They "see" prey by the heat they generate. From the Museum's newest exhibition Our Senses: An Immersive Experience.
