Hooray!!! Today is Friday, friends! Best d – Diy Craft Projects









Hooray!!! Today is Friday, friends! Best day of the week)) Good morning to you !!! ☕️ Please us with your ❤️ likes, and we will share another idea of ​​the experience for children.

Today we will chemize. ⚗️ And our experience is called: "How to see oxygen?"
🌀 You will need:
🔹 Glass jar with lid
🔹 Hydrogen peroxide 3%
🔹 Potassium permanganate
🔹Paper
🔹 Matches
🕹 What are we doing?
🔺 Pour peroxide into the jar so that the bottom is closed
🔺 Add potassium permanganate (pinch)
🔺 Immediately close the lid
🔺 Burn paper flagellum
🔺 Stew it
🔺Open the cover and lower the extinct harness
❓ What happens:
✅ At the interaction of peroxide and potassium permanganate, pure oxygen is released (white smoke on the video). Oxygen sustains combustion, so when we smolder smoldering paper to oxygen, it helps the fire to flare up again.
‼ ️ The experience is conducted only by an adult, children are watching‼ ️
