The human body is a fascinating, mysterious — and sometimes even stinky — piece of machinery! Explore the extraordinary inner workings of your body with this innovative anatomical model. Its see-through exterior holds a number of fun, interactive models that mechanically demonstrate how major body systems work.
Assemble a simple squeeze-bulb pump to circulate red dye through clear tubes, modeling the heart and circulatory system. Expand and contract a balloon with a rubber diaphragm to mimic how air is pulled in and out of the lungs. Discover how the esophagus, stomach, and intestines are connected as you guide a “food” ball through a maze shaped like the digestive tract. Stretch and contract a rubber band to show how the bones and muscles move in the arm. Blow the fart whistle, squeeze the squishy brain, and see the skeleton glow in the dark!
An eight-page, full-color experiment guide takes you through your exploration with fun facts, scientific explanations, and hilarious illustrations. Scan the QR codes to listen to exclusive content from Wow in the World’s Guy Raz and Mindy Thomas. This kit also includes a special toy syringe to add to your collection of classic STEM tools.
