Crystal growing has two benefits! The first is sweetness for children, and the second is the study of chemistry, children will remember a funny, tasty, sweet, colorful chemical reaction for the rest of their lives.
It is necessary
- - jars with a wide neck (or glasses);
- - wooden skewers;
- - clothespins;
- - food colorings;
- - flavors;
- - a lot of sugar.
Instructions
Step 1
You will need a proportion - 10 glasses of sugar for 4 glasses of water. Pour 4 cups of water into a saucepan and add 4 glasses of sugar, put on fire (note that our solution will increase in volume, take a larger pan), bring to a boil over medium heat and add the rest of the sugar, stirring regularly. When the sugar is all dissolved, set the pot away from the heat for 15 minutes.
Step 2
While our solution cools down, prepare the sticks. Soak them in water, then put in sugar to start the formation of crystals, sticks are wet - sugar will stick. After that, be sure to let the sticks with adhered sugar dry completely, if the sticks are even slightly damp - you will not succeed when you put them in a hot sugar solution, all the sugar will crumble and new crystals will have nothing to grow on.
Step 3
Pour sugar syrup into glass jars or glasses, add food coloring. Slowly dip the sticks into the solution and secure with clothespins. Please note that the sticks do not touch either the bottom of the jar or each other, there should be a distance between them for crystal fouling. Place the jars in a warm or sunny place. The crystals will be ready in a week.
