Na, Sodium metal, 500 grams, for highschool science classroom demonstrations

Sodium metal, 500 grams. This is for science experiments for high school classrooms. It can be used to show the properties of sodium metal by cutting off tiny pieces and throwing them in water. KNOW WHAT YOU ARE BUYING BEFORE YOU PURCHASE IT!!! Look up videos of sodium metal on YouTube beforehand. I personally have a YouTube channel that shows exactly how it behaves and how to handle it properly. The channel is called "Backyard Science 2000". You can find many many videos on sodium metal on my channel. Always test and see what you're doing with before moving up to larger amounts as well. This would make a great present for any science teacher or science oriented person. Especially somebody who is into chemistry, physics, or just science in general or somebody who has an element collection. Message me to look for other materials as well. I have nearly every element on the periodic table available for sale. This is a LOT of sodium! Be safe and know what this is before buying! Dangerous!
