Red Flares on the Water
« on: 29/08/2006 18:16:27 »
Some days ago, during a firworks exhibition, they shooted fires to a river, that then kept burning on the water's surface with very brilliant and long-lasting red light.

What are they made of?

(I'm not wondering about the flame's colour: it could be Ca, Li, Sr).

I think they make them using phosphorous which burns extreemly brightly and will burn in and with water.

Red fireworks can be created by adding Strontium or Lithium salts.
