A small amount of sand or rice, bowls, chopsticks, an egg, preferably with a white shell, because a white background can better outline a painting, a colored pen, an awl (or pin), a roll of double-sided tape and a piece of colored paper.

Second, the practice of egg cones

1, choose an egg, preferably with a white shell, because the white background can better set off the pattern. Punch a small hole in the top of the smaller end of the egg with an awl (or a pin or chopsticks). Pay attention to the fragile eggshell, and don't poke the hole too hard.

2. Put down the hole, pour the egg white and yolk into the bowl, then pour water into the egg and wash it clean.

3. Carefully put sand (or rice) into the egg until the big head of the egg can stand on the table. Or light the candle with a lighter prepared in advance to let the dissolved wax flow in, which takes about 15 minutes;

4. Cut a fan with colored paper. Stick the fan on the clown's hat with double-sided tape. Of course, it can also be made into hats or headdresses of other shapes. You can also use wool to make the hair of eggs. If the tumbler is a girl, you can also use red and pink wool as a headdress.

5. Put the clown hat and hair on the small head of the egg (the one with the hole) and stick it tightly. The hat should completely cover the hole.

6. Draw beautiful big eyes and small nose on the eggshell with a colored pen, and then draw a small mouth for the tumbler with a red pen. In this way, a beautiful and lovely tumbler will be done.

Third, the introduction of the tumbler principle.

Objects that are light on the top and heavy on the bottom are relatively stable, that is, the lower the center of gravity, the more stable it is. When the tumbler is in equilibrium in an upright state, the distance between the center of gravity and the contact point is the smallest, that is, the center of gravity is the lowest. After deviating from the equilibrium position, the center of gravity always rises. So the balance of this state is stable.

Balance. Therefore, no matter how the tumbler swings, it will not fall. In order to increase the stability of objects in life, we often increase the weight below, such as fan base, microphone bracket, bus stop sign and so on.

It's fun to teach babies to make tumbler toys with eggs. No matter how you shake it, it can stand up again. Let's have a try!

Eggs are the food that every family eats almost every day. Eggs are nutritious, and eggshells are also useful. You can use it as a toy if you like.
