Take light from the Sun. Make concrete glow!
Four students made the concrete. People can build roads and paths that glow. No other lights would be needed to light the way at night.
Pray people will think of more ways to use the Sun’s light. Concrete that glows is a great idea.

God made the Sun “to give light on the Earth.” (Genesis 1:17)
