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 gave us the Sun! The students took plain concrete. They added to the sand and water mixture. Now the concrete can soak up sunlight all day. It glows at night. Thank God for His many free gifts! God made the Sun “to give light on the Earth.” (Genesis 1:17)
