These are mesmerizing!
I keep seeing this pop up on my dash, and I have to correct something relatively dire.
I don’t know what that cesium + H20 reaction is actually showing, but the real deal doesn’t give you pretty colors….unless you think the colors of blood, fire, and the bright white light of impending death are pretty.
Cesium and water react INCREDIBLY exothermically and explosively. The result is an explosion. And it happens immediately after the cesium touches the water.
Cesium, and other alkali metals, are stored, carefully, in oil, simply because they react so strongly with water, even the water vapor in the air.
DO NOT. EVER. ADD CESIUM TO WATER. WITHOUT EXTREME PROTECTIVE MEASURES. PAIN WILL COME SWIFTLY AND WITHOUT MERCY.
