These are awesome! I've done some of these. Another one that's pretty cool to do is float some oil on top of some water and then drop an ice cube in the oil. It will float! Yes, water expands so much when it freezes into ice that it becomes less dense than oil.
All experiments are amazing. Like other viewers, I also like Diffusion & Elephant toothpaste experiments. Thank you for sharing this wonderful informative video. Take care 🙏🙂
The technical term for the Elephant's Toothpaste experiment is the catalytic decomposition of hydrogen peroxide. Yeast works as the catalyst, but an even better catalyst is Potassium Iodide. you still put the hydrogen peroxide and the dish soap, and you put the potassium iodide when he put the yeast. When hydrogen peroxide decomposes, it releases gas. The dish soap catches the gas and makes it bubble. The catalyst just speeds all of that up. But the foam that comes out is really hot!
All the experiments are amazing..........WOWWW........... can we touch that elephant tooth after it comes out.. I have done all the experiments today it was wonderful........ Tq for this video sir..
As a high school science teacher who has access to 30% hydrogen peroxide and 1000 ml graduated cylinders, with manganese compounds for a macro size experiment with exothermic energy, I like the simplicity and low cost of this microscale experiment. Thanks, L. T.
7th (3:40) is not the ideal gas law... It shows oxygen occupies about 20% of the air. Ideal gas law relates pressure, temperature, and density of an ideal gas.
Hermoso video!! Me encantó, el encuadre, la luz, ritmo, música y la progresión de simple a complejo. Aplausos!!! Me gustaría saber qué principios físicos se ven en cada experimento.. bueno tal vez esa es la idea.. dejarme con la curiosidad.. pero.. el nombre como ayudita vendría bien. Gracias!!! (soy novata en la materia, y gracias a tu video me está gustando más). Saludos de Argentina!
