The video is a series of science experiments and demonstrations. Here's a concise summary:
1. **Visible Doll Experiment**: The host demonstrates how to make a doll invisible using a glass and a fish tank. The doll is submerged in the water and the glass acts as an invisibility machine. The doll disappears under the water.
2. **Water Experiment**: The host shows how to create a water experiment that doesn't fall. The experiment uses a glass jar, elastic bands or hair ties, a stocking, and water. The stocking is placed in the mouth of the jar, water is added, and the jar is turned upside down.
3. **Homemade Game**: The host introduces a homemade game that involves leaves, water, an airtight bag, and a sharp pencil. The game involves sticking the pencils in the bag in turns.
4. **Ultra-Resistant Witches**: The host demonstrates how to make ultra-resistant witches using water-concentrated soap, glycerin, a glass, and a spoon. The host also reveals a secret formula for making super-resistant bubbles.
5. **Fingerprint Technique**: The host teaches a small foot technique for identifying a culprit. The technique involves using a sheet of paper, a pencil, a small container, a glossy with a soft tip, and stamp ink.
6. **Non-Newtonian Balloon**: The host shows how to make a non-Newtonian balloon using an empty plastic bottle, water, a funnel, a balloon, and fine cornstarch. The balloon is inflated and placed in the bottle.
7. **Eskimo Liquid Experiment**: The host demonstrates the Eskimo liquid experiment using water and sanitary alcohol. The experiment involves freezing the liquids at very low temperatures.
8. **Glowing Egg**: The host demonstrates how to make an egg glow using vinegar, an egg, and ultraviolet light. The egg is frozen and then placed under ultraviolet light.
9. **Homemade Telephone**: The host shows how to make a homemade telephone using cardboard or plastic cups, toothpicks, scissors, and wool. The telephone is made by cutting holes in the bottom of the cups, threading the toothpicks through the holes, and tying the threads together.
10. **Ice Race Experiment**: The host demonstrates the ice race experiment using three containers, normal salt, white sugar, and water. The experiment involves adding the ingredients to the containers and observing which ice melts the fastest.
11. **Crazy Straw Game**: The host introduces a game that involves a pin, a bottle cork, and some scissors. The game involves making a hole in a straw and placing a cork in the hole.
12. **Stick Game**: The host shows a game that involves forming a ladder with 11 sticks. The game involves marking different fractions on a ruler and placing the sticks on the ruler according to the marks.
13. **Homemade Ribbon**: The host demonstrates how to make a homemade ribbon using water, oil, salt, and flour. The ribbon is made by pouring the ingredients into a large bowl and mixing them together.
14. **Drawing a Sphere in 3-D**: The host shows how to draw a sphere in 3-D using a hard pencil or 2H for the outline and a soft pencil or 2B for the review. The sphere is drawn by drawing straight lines for each mark and drawing a series of curves to make it look like the sphere is on a cloth.
