    1. This video describes a double displacement (or metathesis) reaction, which is a type of precipitation reaction. Sodium hydroxide and cobalt sulfate are put on opposite side of the drop. The cobalt ions and hydroxide ions are brought together in water via salts that dissolves in water well, forming cobalt hydroxide precipitate to meet in the middle causing the blue precipitate line to form.

    2. The end result looks like a sky full of stars (left side) and a mountain where a meteorite impacted the ground (right side) that looks so dope. Fuck yeah! science!

    3. Can someone let me know what style music this is? I’d love to have it one while working. Very calming
