Dancing sodium.
The sodium metal is reacting with a secondary alcohol in mineral oil.
This reaction produces hydrogen gas, which stick to the small balls of molton sodium, causing them to float.

This was odd how the syringe pauses and restarts well over twenty times, the ping pong ball reactivating the motion. It's just a 1 ml syringe press fit to a 1 ml test test via a piece of pink silicone tubing. I've run it many times and it's extremely resistant to stopping completely, one run over 5 minutes when I finally stopped it.
I bought the syringe for one dollar on eBay from China several years ago and never used it for anything.

That blue is intense! I read about it, is the color in the picture representative for the color in real life?

I recently worked with a Chlorine compressor (takes gaseous chlorine from a big electrolysis cell and turns it liquid) and the liquid Chlorine looked absolutely stunning when shining a flashlight through the watchglass.
