Marshmallow in Vacuum with top 5 Science Experiments for kids! - Summary

Summary

In the video, various experiments are conducted to demonstrate scientific principles. The experiments include:

- **Marshmallow in a Vacuum**: Marshmallows expand in a vacuum due to the air inside them pushing out, and return to normal size when air is reintroduced.
- **Dancing Popcorn**: Baking soda and vinegar create carbon dioxide bubbles that lift popcorn kernels in water, making them appear to dance.
- **Raisins in Soda**: Raisins rise and fall in carbonated soda as bubbles form around them and then pop.
- **Milk and Soap**: Soap breaks down fat in milk, causing food coloring to spread rapidly across the surface.
- **Balloon Race**: Balloons attached to a string track race against each other when released, demonstrating propulsion.

The video is educational and showcases fun ways to learn about science through simple home experiments.

Facts

Here are the key facts from the text:

1. The experiment involves putting a marshmallow in a vacuum container and observing what happens.
2. The marshmallow expands when the air is sucked out of the container.
3. The marshmallow returns to its original size when the air is let back into the container.
4. The experiment is repeated with different types of marshmallows, including giant marshmallows and bunny-shaped marshmallows.
5. The expansion of the marshmallow is due to the air bubbles inside the marshmallow pushing out when the outside air pressure is removed.
6. The air bubbles inside the marshmallow are surrounded by carbon dioxide gas, which is released when the air is sucked out.
7. The experiment demonstrates the concept of air pressure and how it affects objects.
8. The raisins in soda experiment involves dropping raisins into a carbonated drink and observing how they react.
9. The raisins initially sink to the bottom of the container but then rise up to the surface due to the carbon dioxide bubbles attaching to them.
10. The experiment demonstrates the concept of density and buoyancy.
11. The milk and soap experiment involves adding a few drops of food coloring to a container of milk and then adding a small amount of soap.
12. The soap breaks the surface tension of the milk, causing the food coloring to spread and mix with the milk.
13. The experiment demonstrates the concept of surface tension and how it can be broken by adding a surfactant like soap.
14. The DIY balloon rake experiment involves creating a homemade toy using a balloon, straw, and string.
15. The balloon is inflated and then attached to the end of the straw, which is then used to propel the balloon along a string.
16. The experiment demonstrates the concept of air pressure and how it can be used to create motion.
