Knowing more about the amount and type of fat in foods can help a person make healthier eating choices. Vending Machine Foods Test Tubes graphically demonstrate how much fat is found in certain foods. These unique tubes contain "liquifat" - simulated fat that oozes from one end of the test tube to the other - and clearly reminds viewers that too much fat in the diet can lead to health problems. Labels on the tubes enable viewers to compare the fat, calorie, and cholesterol content of the different foods. Each set comes with ten test tubes, display rack, tent card, nylon carrying case, informative, reproducible handout.
