We can use milk to make all kinds of things. Here's how to make plastic:
You will need |
Teaspoon Vinegar(醋) Measuring cup Whole vitamin D milk (nonfat or low-fat) Sauce pan Adult helper Stove |
Do this |
⒈Pour 2 cups (500 ml) of milk into the sauce pan. ⒉Ask the adult to heat the pan slowly on the stove. ⒊Just before the milk boils, bubbles will start to appear on its surface. ⒋When that happens, slowly put in two teaspoons of vinegar. ⒌Keep stirring(搅拌) until the milk becomes rubbery(橡胶状) and hard to move. ⒍Remove the pan from the heat and let it cool. ⒎When the milk is completely cool, remove the solid from the pan, squeeze it into a ball and wash it under cool running water. |
What happened? |
A chemical reaction takes place between a chemical(化学物质) in the warm milk and acid(酸) in the vinegar, and the result is a rubbery solid that does not dissolve in water. The milk has to be heated for this experiment to work. The white glue that comes in a squeeze bottle is one of the many useful things. That can be made from the chemicals in milk. |
