In this video, the presenter demonstrates a series of fun and educational science experiments and DIY projects. Some of the experiments include:
1. **Milk Galaxy:** The presenter pours milk onto a plate, adds food coloring, and then uses dish soap to create a mesmerizing and colorful galaxy effect. This is explained by the dish soap breaking down fat molecules in the milk, causing the food coloring to move and mix.
2. **Banana Messages:** The presenter shows how to write messages or draw on a banana peel using a toothpick. The banana peel turns brown due to an oxidation reaction involving polyphenol oxidase.
3. **Lava Lamp:** A DIY lava lamp is created using a glass filled with oil, water, food coloring, and a fizz tablet. The tablet reacts with the water to produce carbon dioxide bubbles, creating a mesmerizing effect.
4. **Edible Glass:** The presenter demonstrates how to make edible glass that looks like real glass but tastes like candy. It involves boiling a mixture of sugar, corn syrup, and water until it reaches a high temperature.
5. **Fizzing Color Reaction:** Baking soda and vinegar are combined in various glasses, each containing different colors of food coloring. When vinegar is added, it reacts with the baking soda to produce carbon dioxide bubbles, creating colorful fizzing reactions.
6. **Skittles Rainbow:** Skittles are arranged in a circle on a plate, and warm water is poured onto them. The colors from the Skittles travel towards the center of the plate, creating a colorful wheel.
7. **Rainbow Spaghetti:** Spaghetti is cooked, and then it is soaked in colored water to create vibrant and colorful pasta. The longer the spaghetti soaks, the brighter the colors become.
8. **Density Tower:** Different liquids and objects are layered in a glass container based on their density, creating a visually appealing density tower. The presenter explains that density is the ratio of an object's mass to its volume.
9. **Fizz Tablet in Density Column:** A fizz tablet is added to the density column, causing it to jump up and down due to the release of carbon dioxide gas bubbles.
10. **Glow-in-the-Dark Popsicles:** Popsicles are made using tonic water and gummy candy. The tonic water contains quinine, which fluoresces under UV light, giving the popsicles a glow-in-the-dark effect.
11. **Rainbow Rice:** White rice is colored using food coloring and vinegar, then dried to create vibrant and colorful rice for sensory play or decoration.
12. **Lemon Volcano:** A lemon is used as a volcano, with baking soda, food coloring, and dish soap added. When lemon juice is poured in, it creates a fizzy eruption due to the reaction between citric acid and baking soda.
These experiments are not only fun and visually appealing but also provide insights into various scientific principles.
